Information technology is turning into a global �cloud� accessiblefrom anywhere, says Ludwig Siegele. What does that mean for the waypeople conduct business?

ing�became more distributed.Now, this special report will argue,

computing is taking on yet another newshape. It is becoming more centralisedagain as some of the activity moves intodata centres. But more importantly, it isturning into what has come to be called a�cloud�, or collections of clouds. Comput­ing power will become more and more dis­embodied and will be consumed whereand when it is needed.

The rise of the cloud is more than justanother platform shift that gets geeks excit­ed. It will undoubtedly transform the in­formation technology (IT) industry, but itwill also profoundly change the way peo­ple work and companies operate. It will al­low digital technology to penetrate everynook and cranny of the economy and ofsociety, creating some tricky political pro­blems along the way.

Promise of heavenHere we go again, you may think. In orderto generate new demand, the maturing ITindustry keeps creating new buzzwords,often with celestial connotations (�cyber­space�, �blogosphere�), which suggestsome kind of technological nirvana. Thereality is much more down to earth.

Hype is indeed rampant in �cloud com­

Let it rise

IN THE beginning computers were hu­man. Then they took the shape of metal

boxes, �lling entire rooms before becom­ing ever smaller and more widespread.Now they are evaporating altogether andbecoming accessible from anywhere.

That is about as brief a history of com­puters as anyone can make it. The point isthat they are much more than devices in abox or in a data centre. Computing hasconstantly changed shape and location�mainly as a result of new technology, butoften also because of shifts in demand.

The �rst �computers� were indeed peo­ple. The word originally meant an individ­ual who solved equations, often using amechanical calculator. Hundreds of themwere employed by big companies thatneeded to do a lot of number­crunching,such as aeroplane manufacturers. It wasonly around 1945 that the word came to de­scribe machinery.

But even after that, computing kept un­dergoing mutations�or, in the jargon, plat­form shifts. The mainframe, the originalcomputing platform, was dethroned byminicomputers, which in turn gave way topersonal computers, which are now beingpushed aside by hand­held devices andsmartphones. With each step the architec­ture�the underlying structure of comput­

2 puting�. The term entered into IT­speakonly a year ago and has spread vora­ciously. Cloud conferences and cloud blogsare multiplying almost as quickly as cloudstart­ups. Established IT �rms are slappingthe new label on old gear.

In fact, the cloud craze may havepeaked already, if the number of Googlesearches is any guide (see chart 1). Cloudcomputing is bound to go through a�trough of disillusionment�, as Gartner, aresearch �rm, calls the phase in the hypecycle when technologies fail to meet ex­pectations and quickly cease to be fashion­able. Much still needs to be invented forthe computing sky to become truly cloudy.

Yet even if the term is already passé, thecloud itself is here to stay and to grow. It fol­lows naturally from the combination ofever cheaper and more powerful proces­sors with ever faster and more ubiquitousnetworks. As a result, data centres are be­coming factories for computing serviceson an industrial scale; software is increas­ingly being delivered as an online service;and wireless networks connect more andmore devices to such o�erings.

All this allows computing to be disag­gregated into components�or �services�,in IT parlance. This is why European tech­nologists such as Lutz Heuser, head of re­search at SAP, a German software giant,like to refer to it as the �internet of ser­vices�. The cloud metaphor seems moreapt. The internet is used mainly by peoplewith personal computers and a physicalnetwork connection. Cloud applications,on the other hand, will be used by billionsof devices of all kinds, many of them un­tethered, but will be connected to the �in­ternet of things�.

In some ways the cloud is already hang­ing in the sky, especially for consumers. Ac­cording to a recent study, 69% of Ameri­cans connected to the web use some kind

of �cloud service�, including web­basede­mail or online data storage (see chart 2).The best example is Google, the biggest on­line search company by far, which now of­fers a plethora of web­based applicationssuch as word­processing or online spread­sheets.

Learning to �oatCompanies, too, have been moving intothe cloud, albeit much more cautiously. Fi­nancial institutions in particular have forsome time been building �computinggrids�. Firms that provide enterprise soft­ware as a service (SaaS) over the internet,such as Salesforce.com and NetSuite, havebeen growing steadily.

In the years to come companies are like­ly to venture much farther. For one, opera­tors of computing clouds such as Amazonand Google have shown that this is a farmore e�cient way of running IT systems.Secondly, many �rms will �nd they haveno choice. The way in which their IT infra­structure has grown is proving unsustain­able. Most corporate data centres today arecomplex warrens of underused hardwarethat require more and more people, spaceand power to keep them going. The currenteconomic malaise will increase the pres­sure on companies to become more e�­cient. More has to be done with less, whichis cloud computing’s main promise.

This special report will chronicle therise of the cloud and try to predict where itis heading. It will start by looking at thetechnology. Computing clouds are im­mensely complex, but can be roughly di­vided into three layers: infrastructure, ap­plications and the periphery where theymeet the real world. These will be discuss­ed in turn. The report will go on to considerthe impact the cloud will have on the IT in­dustry and the economy as a whole. Theconclusion will look at what might stopthe cloud from growing ever thicker: regu­

lation and worries about the safety of bothpersonal and corporate data.

Irving Wladawsky­Berger, a technol­ogy visionary at IBM, compares cloudcomputing to the Cambrian explosionsome 500m years ago when the rate ofevolution speeded up, in part because thecell had been perfected and standardised,allowing evolution to build more complexorganisms. Similarly, argues Mr Wladaw­sky­Berger, the IT industry spent much ofits �rst few decades developing the basiccomponents of computing. Now thatthese are essentially standardised, biggerand more diverse systems can emerge.�For computing to reach a higher level�, hesays, �its cells had to be commoditised.� 7

IT IS almost as easy as plugging in a laserprinter. Up to 2,500 servers�in essence,

souped­up personal computers�arecrammed into a 40­foot (13­metre) shippingcontainer. A truck places the container in­side a bare steel­and­concrete building.Workers quickly connect it to the electricgrid, the computer network and a watersupply for cooling. The necessary softwareis downloaded automatically. Within fourdays all the servers are ready to dish upvideos, send e­mails or crunch a �rm’s cus­tomer data.

This is Microsoft’s new data centre inNorthlake, a suburb of Chicago, one of theworld’s most modern, biggest and most ex­pensive, covering 500,000 square feet(46,000 square metres) and costing$500m. One day it will hold 400,000 serv­ers. The entire �rst �oor will be �lled with200 containers like this one. Michael Ma­nos, the head of Microsoft’s data centres, isreally excited about these containers. Theysolve many of the problems that tend tocrop up when putting up huge data cen­tres: how to package and transport serverscheaply, how to limit their appetite for en­ergy and how to install them only whenthey are needed to avoid leaving expen­sive assets idle.

But containers are not the only innova­tion of which Mr Manos is proud. Micro­soft’s data centres in Chicago and acrossthe world are equipped with software thattells him exactly how much power eachapplication consumes and how much car­bon it emits. �We’re building a global infor­mation utility,� he says.

Engineers must have spoken with simi­lar passion when the �rst moving assem­bly lines were installed in car factories al­most a century ago, and Microsoft’s datacentre in Northlake, just like Henry Ford’s�rst large factory in Highland Park, Michi­gan, may one day be seen as a symbol of anew industrial era.

Before Ford revolutionised carmaking,automobiles were put together by teams ofhighly skilled craftsmen in custom­builtworkshops. Similarly, most corporate datacentres today house armies of �systemsadministrators�, the craftsmen of the infor­mation age. There are an estimated 7,000such data centres in America alone, most

of them one­o� designs that have grownover the years, re�ecting the history ofboth technology and the particular use towhich it is being put. It is no surprise thatthey are egregiously ine�cient. On aver­age only 6% of server capacity is used, ac­cording to a study by McKinsey, a consul­tancy, and the Uptime Institute, athink­tank. Nearly 30% are no longer in useat all, but no one has bothered to removethem. Often nobody knows which appli­cation is running on which server. A wide­ly used method to �nd out is: �Let’s pull theplug and see who calls.�

Limited technology and misplaced in­centives are to blame. Windows, the mostpervasive operating system used in datacentres, allows only one application to runon any one server because otherwise itmight crash. So IT departments just keptadding machines when new applicationswere needed, leading to a conditionknown as �server sprawl� (see chart 3).This made sense at the time: servers werecheap, and ever­rising electricity bills weregenerally charged to a company’s facilitiesbudget rather than to IT.

To understand the technology neededto industrialise data centres, it helps to lookat the history of electricity. It was only afterthe widespread deployment of the �rotaryconverter�, a device that transforms onekind of current into another, that di�erentpower plants and generators could be as­sembled into a universal grid. Similarly, atechnology called �virtualisation� now al­lows physically separate computer sys­tems to act as one.

Virtually newThe origins of virtualisation go back to the1960s, when IBM developed the technol­ogy so that its customers could make betteruse of their mainframes. Yet it lingered inobscurity until VMware, now one of theworld’s biggest software �rms, applied it tothe commodity computers in today’s datacentres. It did that by developing a smallprogram called hypervisor, a sort of elec­tronic tra�c cop that controls access to acomputer’s processor and memory. It al­lows servers to be split into several �virtualmachines�, each of which can run its ownoperating system and application.

�In a way, we’re cleaning up Microsoft’ssins,� says Paul Maritz, VMware’s boss anda Microsoft veteran, �and in doing so we’reseparating the computing workload fromthe hardware.� Once computers have be­come more or less disembodied, all sortsof possibilities open up. Virtual machinescan be �red up in minutes. They can bemoved around while running, perhaps toconcentrate them on one server to save en­ergy. They can have an identical twinwhich takes over should the original fail.And they can be sold prepackaged as �vir­tual appliances�.

VMware and its competitors, whichnow include Microsoft, hope eventually toturn a data centre�or even several ofthem�into a single pool of computing,storage and networking resources that canbe allocated as needed. Such a �real­timeinfrastructure�, as Thomas Bittman ofGartner calls it, is still years o�. But the nec­essary software is starting to become avail­able. In September, for instance, VMwarelaunched a new �virtual data­centre oper­ating system�.

Perhaps surprisingly, it is Amazon, a bigonline retailer, that shows where things areheading. In 2006 it started o�ering a com­puting utility called Amazon Web Services(AWS). Anybody with a credit card canstart, say, a virtual machine on Amazon’svast computer system to run an applica­tion, such as a web­based service. Devel­opers can quickly add extra machines

2 when needed and shut them down if thereis no demand (which is why the utility iscalled Elastic Computing Cloud, or EC2).And the service is cheap: a virtual mach­ine, for instance, starts at 10 cents per hour.

If Amazon has become a cloud­com­puting pioneer, it is because it sees itself asa technology company. As it branched outinto more and more retail categories, it hadto develop a sophisticated computing plat­form which it is now o�ering as a servicefor a fee. �Of course this has nothing to dowith selling books,� says Adam Selipsky, incharge of product management at AWS,�but it has a lot to do with the same tech­nology we are using to sell books.�

Yet Amazon is not the only big onlinecompany to o�er the use of industrial­scale data centres. Google is said to be op­erating a global network of about threedozen data centres loaded with more than2m servers (although it will not con�rmthis). Microsoft is investing billions andadding up to 35,000 servers a month. Oth­er internet giants, such as Yahoo!, are alsobusy building huge server farms.

In some places this has led to a veritabledata­centre construction boom. Half a doz­en are being built in Quincy, a hamlet inthe middle of America’s Washington state,close to the Columbia River. The attractionis that its dams produce plenty of low­costpower, which apart from IT gear is themain input for these computing farms. Onaverage, cooling takes as much power ascomputing. Microsoft’s new data centrenear Chicago, for instance, has three sub­stations with a total capacity of 198MW, asmuch as a small aluminium smelter.

But cheap electricity is only one, albeitimportant, criterion for choosing the site ofa data centre. Microsoft currently feeds 35sets of data into an electronic map of theworld, including internet connectivity, theavailability of IT workers, even the airquality (dry air makes a good coolant), tosee where conditions are favourable andwhich places should be avoided. Appar­ently Siberia comes out well.

Google, for its part, seems to be think­ing of moving o�shore. In August it ap­plied for a patent for water­based data cen­tres. �Computing centres are located on aship or ships, anchored in a water bodyfrom which energy from natural motion ofthe water may be captured, and turnedinto electricity and/or pumping power forcooling pumps to carry heat away,� saysthe patent application.

Many chief information o�cers wouldlove to take their IT infrastructure out tosea and perhaps drown it there. Even as de­

mand for corporate computing continuesto increase, IT budgets are being cut. At thesame time many �rms’ existing IT infra­structure is bursting at the seams. Accord­ing to IDC, a market­research �rm, a quar­ter of corporate data centres in Americahave run out of space for more servers. Forothers cooling has become a big constraint.And often utilities cannot provide the extrapower needed for an expansion.

Fewer, bigger, betterSo IDC thinks that many data centres willbe consolidated and given a big makeover.The industry itself is taking the lead. For ex­ample, Hewlett­Packard (HP) used to have85 data centres with 19,000 IT workersworldwide, but expects to cut this down tosix facilities in America with just 8,000employees by the end of this year, reduc­ing its IT budget from 4% to 2% of revenue.

Other large organisations are followingsuit. Using VMware’s software, BT, a tele­coms �rm, has cut the number of servers in

its 57 data centres across the world from16,000 to 10,000 yet increased their work­load. The US Marine Corps is reducing thenumber of its IT sites from 175 to about 100.Both organisations are also starting tobuild internal clouds so they can move ap­plications around. Ever more �rms are ex­pected to start building similar in­house, or�private�, clouds. The current economicmalaise may speed up this trend as compa­nies strive to become more e�cient.

But to what extent will companies out­source their computing to �public� clouds,such as Amazon’s? James Staten of Forres­ter Research, a market­research �rm, saysthe economics are compelling, particularlyfor smaller �rms. Cloud providers, he says,have more expertise in running data cen­tres and bene�t from a larger infrastruc­ture. Yet many �rms will not let companydata �oat around in a public cloud wherethey could end up in the wrong hands. Theconclusion of this report will consider thequestion of security in more detail.

It does not help that Amazon and Goo­gle recently made headlines with serviceinterruptions. Few cloud providers todayo�er any assurances on things like con­tinuity of service or security (called �ser­vice­level agreements�, or SLAs) or take onliability to back them up.

As a result, says Mr Staten, cloud com­puting has not yet moved much beyondthe early­adopter phase, meaning thatonly a few of the bigger companies are us­ing it, and then only for projects that do notcritically a�ect their business. The Wash­ington Post, for instance, used Amazon’sAWS to turn Hillary Clinton’s WhiteHouse schedule during her husband’stime in o�ce, with more than 17,000 pages,into a searchable database within 24hours. NASDAQ uses it to power its serviceproviding historical stockmarket informa­tion, called Market Replay.

Stefan van Overtveldt, the man incharge of transforming BT’s IT infrastruc­ture, thinks that to attract more customers,service providers will have to o�er �virtualprivate clouds�, fenced o� within a publiccloud. BT plans to o�er these as a servicefor �rms that quickly need extra capacity.

So there will be not just one cloud but anumber of di�erent sorts: private ones andpublic ones, which themselves will divideinto general­purpose and specialised ones.Cisco, a leading maker of networking gear,is already talking of an �intercloud�, a fed­eration of all kinds of clouds, in the sameway that the internet is a network of net­works. And all of those clouds will be fullof applications and services. 7

WANT to become a programmer in 20minutes? With the program from Ice­

berg, a start­up, you can. Just open the �get­ting started wizard� and pick the type ofapplication, say �project management�.Type in its �business objects��things like�client�, �team� and �members��and tellthe tool how they relate to each other.Then design some input forms and de�nethe process for getting a project done. An­other click and you are ready to go.

In reality, of course, things are not thatsimple. And many professional program­mers will sco� at the development tool asa mere toy. Yet Iceberg and similar out�tsdemonstrate that geeks are losing their mo­nopoly on programming. Now, with a bitof patience, anybody can create a simpleapplication, for instance, to collaboratewith colleagues or to draw an online map.

This democratisation of programming,however, is only a small part of somethingmuch deeper: a fundamental change in thenature of software. It is not just that moreand more software will become a servicedelivered online. More importantly, appli­cations, web­based or not, will no longercome as a big chunk of software, but willbe made up of a combination of electronicservices�a shift that has picked up a lot ofspeed since computing began moving intothe cloud.

To understand this new way of build­ing applications, known as �service­ori­ented architecture� (SOA), think of a culi­nary analogy. Whereas the old chunk ofsoftware resembles a precooked meal thatjust has to be popped into the oven, thenew architecture is more like a restaurant.It is a service in itself but also a combina­tion of sub­services. There is the waiter

who takes the order and conveys it to thekitchen. There is the cook who preparesthe food. And there are the cleaners whokeep the place tidy. Together they create the�application�: a restaurant.

An attack of the vapoursThe importance of this shift from a mono­lithic product to services is hard to over­state. In a sense, it has seeded the cloud, al­lowing the droplets�the services thatmake up the electronic vapour�to form. Itwill allow computing to expand in all di­rections and serve ever more users. Thenew architecture also helps the less techni­cally minded to shape their own clouds,using such tools as Iceberg’s.

Just as for the industrialisation of datacentres, there is a historic precedent for thisshift in architecture: the invention of mov­able type in the 15th century. At the time,printing itself was not a new idea. But itwas Gutenberg and his collaborators whothought up the technologies needed tomake printing available on a mass scale,creating letters made of metal that could bequickly assembled and re­used.

Similarly, the concept of modularityhas been around since the early days ofcomputing. �Everything in computer sci­ence is to just write less code. What is thetechnique for writing less code? It’s calledsubroutines,� said Bill Gates, Microsoft’sfounder, in a recent interview. A subrou­tine is a part of a program that can be re­used, just like movable type. The idea, saysMr Gates, has always been to apply thisprinciple of a subroutine more broadly.

Yet this did not happen, mainly be­cause the cost of computing fell much fast­er than that of communications. Ever

cheaper and more powerful chips made itpossible to move from mainframes tominicomputers to personal computers(PCs) and now to hand­held devices. Butconnecting all these pieces remained di�­cult and expensive, which meant that suchdevices all had to come with their owndata and chunky programs. Now, thanks toplenty of cheap bandwidth and more andmore wireless connectivity, computing isable to regroup into specialised services, orMr Gates’s subroutines: �We now live in aworld whereð[a] subroutine can exist onanother computer across the internet.�

Part of Gutenberg’s genius was to recog­nise the need for all the letters to be identi­cal in height so they could be easily com­bined. Similarly, for computing services towork there had to be robust technical stan­dards. Only a few years ago this seemed farbeyond the IT industry’s reach. Most �rmsinsisted on their proprietary technology,mostly to lock in their customers. Again,cheaper communications helped to bringabout change. The success of the internetdemonstrated the huge bene�ts of openstandards and forced vendors to agree oncommon ways for their wares to work to­gether. One result is a stack of somethingcalled �web­services� standards.

Service­oriented architecture �rstshowed up in open­source software butwas quickly adopted by big enterprise­software vendors because they had apressing need for it, says Jim Shepherd ofAMR Research, a consultancy. Big softwarevendors, for instance, had to �nd a way tountangle the hairball of code that their pro­ducts had become, or else they themselveswould choke on it. Customers wantedmore �exible and extensible programs.

2 Think back to the gastronomic exam­ple. A precooked meal is hard to change,and so are traditional software applica­tions. By contrast, a restaurant can easilychange its menu and its style of operation.Similarly, SOA­based software allowscompanies to alter their business process­es, such as the way they handle orders tocollect cash.

SAP, a German software �rm, was oneof the �rst companies to put this service­oriented architecture front and centre.Starting in 2003, it developed, among oth­er things, a new corporate­software pack­age that did away with monolithic applica­tions, such as programs to keep track of acompany’s �nances or manage its relation­ship with customers. Instead, it introduceda collection of re­usable components thatcould be strung together at will.

IBM, too, is a fan of SOA and web ser­vices. But its approach is somewhat di�er­ent, given that it does not sell business ap­plications but makes most of its moneyfrom IT services and software to managethe underlying computing infrastructure.IBM uses SOA mainly to help �rms inte­grate their increasingly complex and dispa­rate IT systems. Its software turns theminto a collection of services that can bewoven into business processes.

The approaches may be di�erent butthe vision is the same: to create IT systemsthat adapt to the business needs of compa­nies and allow them to connect. �When Iwant to do something new�, explainsSteve Mills, the boss of IBM’s softwaregroup, �I do not need to build a new appli­cation but can use the pieces I alreadyhave.� To Peter Zencke, who led the devel­opment of SAP’s new package, its most ex­citing feature is that �any of the processcomponents can now become a serviceprovided by some other �rm.�

Despite millions of dollars spent onmarketing SOA, it has not really taken o�yet. But many web­based applications forconsumers rely on this concept. The primeexample is Google Maps. When the onlinegiant launched the service, programmersquickly �gured out how to mix the mapswith other sources of information. This ishow, for example, Housingmaps.com wascreated, a combination of a Google mapwith the rental and sales listings fromCraigslist, a website for classi�ed ads. Itwas one of the �rst �mash­ups�, as suchcombinations have come to be called.

Since then the number of such mash­ups has exploded, thanks mainly to ser­vices like Microsoft’s Pop�y and Yahoo!Pipes. In essence these are graphical pro­

gramming tools. Users drag and drop�modules��data feeds providing such in­formation as pictures, headlines andsearch results�and weave them together.

Most of these mash­ups are still toys,but �rms o�ering software as a servicehave started o�ering similar combina­tions. In April Salesforce.com and Googleannounced that they would integrate theironline services. Users of Salesforce, whichhelps �rms manage their customer rela­tionships, can now quickly switch to Goo­gle’s web­based applications.

Smaller �rms have already started toweave a network of services. OpSource, aSilicon Valley start­up, for instance, pro­vides basic services for other SaaS �rmsand web companies. TriCipher, anotherCalifornian newcomer, authenticates us­ers of web applications. Ribbit, for its part,allows these services to add voice commu­nications to their o�erings.

Yet it is unlikely that the software cloudwill end up as a vast nebula of thousandsof specialised services. Even creating a ser­vice­oriented architecture is �no silver bul­let� against complexity, in a famous phraseby Frederick Brooks, an elder of computerscience. Although web services allow on­line o�erings to connect, for instance, it iscostly to synchronise their data. And itwould not make sense for any �rm to betits business on simple mash­ups.

As software markets mature, they tendto form two kinds of clumps: integratedsuites of applications, and platforms ontop of which others can build programs.Both forms are already emerging. On theapplications side there is Google Apps and

Zoho, which is even more comprehensive.It encompasses a total of 18 applications,including word processing, project man­agement and customer­relationship man­agement (CRM).

As for platforms, there are already plen­ty, in di�erent shapes and sizes. For enter­prise applications, SAP has built one calledNetweaver. Oracle o�ers something simi­lar called Fusion. Last year, Salesforcelaunched a �platform as a service�, allow­ing other �rms to use the plumbing thatsupports its own CRM o�ering.

More recently platforms for consumerservices have been proliferating. Face­book, a social network, was the �rst to be­come one in 2007. Other big online �rmshave followed suit or will do so soon: Goo­gle with App Engine, Yahoo! with Y!OSand Microsoft with a �cloud operating sys­tem� thought to be called Windows Strata.Some predict a platform war to rival theepic �ghts between Microsoft’s Windowsand Apple’s Macintosh.

Never say dieWhat shape will the software cloud take,other than being a vast collection of ser­vices? In one way it will look much like theold software world. There will be a few bigplatforms, akin to today’s operating sys­tems, and most applications will be writ­ten to one of these platforms.

What is less clear is just how much ofbusiness and consumer software will mi­grate into the cloud, and how fast. The an­swer depends on whom you ask. Unsur­prisingly, Marc Benio�, Salesforce’sfounder and chief executive, argues thatweb applications will spell the �death ofsoftware�. But people are not about tothrow out their powerful PCs or other �cli­ent� devices, if only because many ofthem still work o�ine at times. Similarly,companies will always want to keep someapplications in­house, for reasons of secu­rity, regulation or simply to maintain con­trol. Ray Ozzie, Microsoft’s chief softwarearchitect, promotes something called�software plus services�, meaning thatcustomers will settle on �the right mix ofold and new stu��.

If history is any guide, Mr Ozzie is moreon the mark. Even the biggest changes in IThave never spelt the death of anything,notes Josh Greenbaum of Enterprise Ap­plications Consulting. IBM, for instance, isstill making money with mainframes.

So the software cloud, just like its hard­ware underpinnings, will be very diverse.But how will people make use of this kindof computing? 7

IT WILL take something with a lot morebang to replace a medium that is thou­

sands of years old. That was the prevailingreaction when Amazon last November an­nounced the launch of Kindle, an electron­ic book reader the size of a paperback thatcan store more than 200 volumes. Yet bythe end of this year Amazon will have soldnearly 380,000 Kindles, says Mark Maha­ney, an analyst with Citigroup, a bank.�Turns out the Kindle is becoming the iPodof the book world,� he recently wrote in anote to clients, in a reference to Apple’siconic music player.

It is certainly not the Kindle’s looks thatexplain its success. Compared with theiPod, its design looks very last century.Software and battery life, too, leave a lot tobe desired. The chief attraction of the de­vice is the ease with which it can be used tobuy books and other content. Equippedwith a mobile­phone modem, the Kindlecan simply pull new reading material outof the air. Users do not even have to have awireless service contract. �Our vision is tohave every book that has ever been inprint available in less than 60 seconds,� ex­plains Je� Bezos, Amazon’s boss.

It remains to be seen whether the Kin­dle will become a cultural phenomenonlike the iPod, of which around 160m havebeen sold so far. Amazon, for its part, isdownplaying the Kindle’s success and willnot con�rm any sales estimates. But it issafe to say that, once the next generation ofwireless networks is up and running, hun­dreds of millions of devices will come, likethe Kindle, with built­in radio connectivity(see chart 5). Digital cameras will automati­cally upload pictures. Smart meters willsend readings of how much electricity ahouse consumes. All kinds of sensors willbe able to send messages, even things likedipsticks when tanks of liquid are low.

The relationship of these devices tocloud computing may not be obvious. Butif huge data centres and applications makeup the cloud itself, then all the hardwareand software through which it connectsand communicates with the real world areits periphery. In IT speak, this is known asthe �front end� or �client side�.

As the Kindle and other examplesshow, this layer does not have much to do

with the user interface or client device ofold. It will do a lot of computing itself. Itwill come in all shapes and sizes, depend­ing on what the user wants to do. And itwill not just distribute information, as theweb does, but collect it as well. The analo­gy that springs to mind here is a theatreperformance with audience participation:the electronic cloud will adapt to whateverit engulfs.

As you like itJust like computing itself, the dominantuser interface has evolved continually. Inthe days of the mainframe, when comput­ers and their peripherals �lled entirerooms, people communicated with thesemachines �rst via punch cards and thenvia green­glowing monitors, which weresimply dumb terminals. Only with the riseof personal computers did the user inter­face become more intelligent, responsiveand graphical.

The �rst version of the web was thus abrief step backward. To be sure, browsersbrought colour and graphics to the hither­to text­based internet, but they were asdumb as the mainframe terminal. This haschanged only in recent years. A bundle ofweb­development techniques dubbedAJAX and multimedia software such asAdobe’s Flash and Microsoft’s Silverlightnow allow programmers to write what arecalled �rich internet applications� (RIA).

Whatever the buzzword, the principleis much the same. Servers no longer dishup simple hypertext markup language(HTML), the web’s early lingua franca. In­creasingly, web pages are bona �de piecesof software that are executed in the brows­er. Users of Web 2.0 sites who venture intomenu items such as �view source� in theirbrowsers can sometimes see thousands oflines of code.

In recent months the browser has be­come even more of a platform for otherprograms, akin to an operating systemsuch as Windows. The main driver of thistrend is Google, with its huge strength indistribution that can only gain from moreand more software being o�ered as a ser­vice. In May 2007 the Silicon Valley �rmlaunched Gears, a program that allowsweb applications to be used o�ine, and inSeptember this year it released a newbrowser called Chrome. Its most impor­tant feature is that it can execute several so­phisticated web applications at once.

Although for now the internet browserwill remain the main vehicle for people tointeract with the cloud, other forms arecoming to the fore. One is the �widget�, asnippet of code that often lives on a PC’sdesktop and allows the user to get a quickpersonalised view of a set of data. The ideais that a salesperson, for instance, shouldnot have to �re up an entire application forcustomer­relationship management to�nd out which leads to follow up.

More importantly, there is now a great­er variety of hardware through which toaccess the cloud. Already, desktop and lap­top computers are starting to lose their mo­nopoly for sur�ng the web as smaller de­vices such as smart mobile phones andvarious forms of portable computers startto compete with them.

Asus, a Taiwanese computer­maker,started the trend when it launched a small,cheap laptop called �Eee� a year ago. Nowthere are dozens of these devices. Gartnerreckons that 5.2m of these �mini­note­books� will be sold this year, 8m next andas many as 50m in 2012.

Perhaps the best indicator of things tocome is Intel, a huge chipmaker. It made afortune selling processors for servers, per­sonal computers and laptops. In June the

2 �rm launched a new line of chips calledAtom, designed to power what it calls �net­books� and �mobile internet devices�(MIDs), mainly intended for sur�ng theweb. Intel is also the driving force behindWiMAX, a technology for wireless broad­band access to the internet. It wants to puta WiMAX radio chip into as many devicesas possible, from portable computers tospecialised gadgets such as the Kindle.

Apple’s iPhone and its App Store,which allows iPhone and iPod owners todownload applications, also provide aforetaste of how important wireless de­vices will be for the cloud. Apple launchedApp Store only in July. Two months later ithad already tallied 100m downloads,meaning that it took o� much faster thanApple’s highly successful iTunes musicstore. Many of the programs on o�er con­nect to the cloud, including news feeds,multi­player games and a service thatkeeps track of the latest polls for America’spresidential election.

You can take it with youThe plethora of devices wirelessly con­nected to the internet will speed up a shiftthat is already under way: from a �device­centric� to an �information­centric� world,in the words of VMware’s Paul Maritz. Upin the cloud there will be a body of data foreach individual that will accompany themthrough life, he explains, and it will not betied to any particular device, as it is today.

Again, what will make this possible is

virtualisation�this time of client devices,not servers. With the help of software fromVMware and others, some �rms have al­ready virtualised their employees’ desktopcomputers, which allows them to be man­aged centrally. Operating systems and ap­plications will no longer run only on theemployee’s PC but on a virtual machine ina data centre that can be accessed remotely,theoretically from any PC in the world.Sooner or later mobile devices will also be­come virtualised. Users will be able to usetheir applications and data on whichevergadget they have at hand.

Yet the cloud’s interface is designed notmerely to provide information but to gath­er it as well. The future belongs to servicesthat respond in real time to informationprovided either by their users or by non­human sensors, predicts Tim O’Reilly, thefounder of O’Reilly Media, a publisher oftechnology books who coined the term�Web 2.0�. Such �live applications�, hesays, will get better the more data they areable to collect�and there will be plenty asthe cloud expands.

One of the �rst examples of such a ser­vice was Google. What originally put thesearch service ahead of the competitionwhen it was launched a decade ago was itsway of harvesting the information provid­ed by web users in linking to other sites:the more links point to a page, the moreuseful it must be. These days most links aregenerated by computers, so the originalform of this �page rank� algorithm has

long since been scrapped. But Google’s ap­proach is still the same: mining informa­tion provided by web users, such as theirsearch histories, to provide more relevantsearch results and more e�ective and tar­geted advertising.

The direct link to users also allows �rmssuch as Google continuously to improvetheir interface, something traditional soft­ware­makers were not able to do. At anygiven time Google is running dozens oftests to optimise the look and feel of its of­ferings. This makes web applications farless technology­driven and much moreuser­oriented, says IBM’s Mr Wladawsky­Berger. �They are much more inspired bywhat goes on in the real world.�

A raft of start­ups is also trying to builda business by observing its users, in e�ectturning them into human sensors. One isWesabe (in which Mr O’Reilly has invest­ed). At �rst sight it looks much like any per­sonal­�nance site that allows users to seetheir bank account and credit­card infor­mation in one place. But behind the scenesthe service is also sifting through its mem­bers’ anonymised data to �nd patterns andto o�er recommendations for future trans­actions based, for instance, on how much aparticular customer regularly spends in asupermarket. Wireless devices, too, will in­creasingly become sensors that feed intothe cloud and adapt to new information.

Nokia, for its part, is planning to buildall kinds of sensors into mobile phones tomonitor things like movement, barometricpressure or even the owner’s health,which many experts expect to become abig new trend. Sensors could also be usedto record people’s activities, creating whatsome already term a �lifelog��raising allkinds of privacy concerns.

As wireless technology gets better andcheaper, more and more di�erent kinds ofobjects will connect directly to the cloud.SAP, the German software­maker, haslaunched a research project called �The In­ternet of Things� to see what can be donewith the resulting information. As part ofthat project, an initiative called the �FutureFactory� is now under way to investigatehow intelligent tags can make manufactur­ing more adaptive and e�cient.

More and more data get you only so far,however. In the end, Google’s search re­sults and its text­based online advertise­ments are relevant to users only becausethe �rm has devised clever ways to siftthrough them, says Hal Varian, the �rm’schief economist. The big challenge of thecloud will be to connect the myriad data init and make them pro�table. 7

EVEN elephants can die. In 1993 extinc­tion came close for IBM, then the

world’s largest computer­maker (it hassince been overtaken by HP). Its main­frame business was collapsing and pro�tswere plummeting. At that point LouisGerstner took over as chief executive andmanaged to turn the company around.�Only a handful of people understandhow precariously close IBM came to run­ning out of cash in 1993,� he writes in hismemoir, �Who Says Elephants Can’tDance?� �Whether we would have had to�le for bankruptcy, I can’t say.�

There are many reasons why IBM near­ly went belly­up, not least the fact that BigBlue had become a bureaucratic monster.But most critically, it had failed to adapt tothe industry’s �rst big platform shift,which only really made itself felt in the ear­ly 1990s: the move from mainframes tosmaller machines, �rst so­called minicom­puters, then personal computers. �IBMwas slow, very slow, in delivering distri­buted computing, and many small compa­nies moved in to �ll the gap,� Mr Gerstnerwrites.

It is unlikely that the move into thecloud will produce a similar near­death ex­perience or even a real casualty�if only be­cause IBM still stands as a warning. Butthat does not mean that the structure of theIT industry will remain unchanged, northat the economics will stay the same.Once the IT sky really clouds over, individ­

ual �rms’ share of the global IT budget (seechart 6) will shift.

The move to distributed computing,which started in the mid­1980s, led to a bigchange in the IT industry. In the era of themainframe computing came in a verticallyintegrated package, mainly from IBM. Withdistributed computing the industry be­came a stack of horizontal layers. In cor­porate IT these were mainly hardware, thenetwork, infrastructure software (such asoperating systems and databases), enter­prise applications and IT services.

Not all of these layers were createdequal. Computer­makers commanded athicker one, for instance, but software com­panies were more pro�table. The key pro­gram was the operating system, both onservers and on personal computers (�cli­ents�). It was the standard to which othercomponents of IT systems had to conform.Usually this was a version of Windows,which made Microsoft the IBM of this newera of computing.

Cloud computing is unlikely to bringabout quite such a dramatic shift. In es­sence, what it does is take the idea of distri­buted computing a step farther. Still, it willadd a couple of layers to the IT stack. One ismade up of the cloud providers, such asAmazon and Google. The other is softwarethat helps �rms to turn their IT infrastruc­ture into their own cloud, known as a �vir­tual operating system for data centres�.

Drawing a neat diagram of the IT stack

will also become increasingly di�cult be­cause the layers are becoming less distinct.In a world of services it often does notmake sense to think of hardware and soft­ware separately, argues Padmasree War­rior, the chief technology o�cer of Cisco.Both need to be blended to o�er new ser­vices, she says.

Mix and matchEven though the IT stack may not changeall that much, the perceived value of thedi�erent layers will shift, and with it theamount of pro�t IT �rms can make fromeach of them. Who will lose and who willwin depends on how much of computing

eventually moves into the cloud. In the �rst round almost everybody in

the IT industry will do well as the cloudsare being built. The biggest winners arelikely to be hardware­makers, says MarkStahlman of Gartner: �Hardware alwayswins when new demand for computing isuncovered. And we haven’t had such asweeping global demand since the 1990s.�

But in the longer term there will be rela­tive winners and losers. The hardwarebusiness could actually �nd itself in thelosing group. Its margins could getsqueezed as cloud computing matures be­cause there will be fewer customers withmore buying power, says James Staten ofForrester Research. Large cloud providerscan dictate how to build servers and atwhat price, he notes.

All that may explain why hardware­makers were among the �rst to jump onthe cloud­computing bandwagon. So far,they have done only what Mr Staten calls�cloud­washing�: relabelling existing pro­ducts that help customers build a more�exible IT infrastructure. But they are alsopreparing for a time when more moneycan be made building clouds than buildingcomputers. IBM and HP, for instance, haveteamed up with other �rms and universi­ties to design new cloud architectures.

Which side of the fence?In the long run, says Mr Staten, hardware­makers may be torn between supplyingcloud providers or becoming providersthemselves. Being both will not be easy,because the �rms would be competingwith their biggest customers. Dell seems tohave decided to be a cloud supplier. SunMicrosystems is a candidate to become aprovider; it is o�ering a cloud­like servicecalled Network.com, albeit not very suc­cessfully. HP and IBM, already used to thebalancing act of selling hardware and pro­viding IT services, will try to do both.

Makers of traditional software will �ndthe going even tougher. With the advent ofopen­source software, in particular Linux,selling operating systems had already be­come less pro�table. In a virtual worldthey will become even more commodi­tised, which is bad news for Microsoft.Many business applications no longerneed a big, general­purpose server operat­ing system but can use a specialised one,which should put pressure on prices. Onclient computers, more and more applica­tions are written to run in browsers, not onany particular operating system.

Makers of business applications arealso on the defensive. Traditionally they

have made billions by selling their pro­grams, often demanding hefty sums to in­stall them and then charging an annualmaintenance fee for upgrades and techni­cal support. But this highly lucrative busi­ness model has come under increasingpressure, says Michael Cusumano, a pro­fessor at the Massachusetts Institute ofTechnology (MIT).

For one, he says, software vendors willhave to �nd new ways to charge for theirwares: in the cloud, tying licensing fees tothe number of users, for instance, will bedi�cult, since services will mostly be con­sumed by other machines. More impor­tantly, the corporate world has becomeless and less willing to buy software forlarge sums of money, so software �rms list­ed on America’s stockmarkets now makemost of their pro�ts from maintenanceand other services (see chart 7). SAP will in­crease its annual maintenance fees to atleast 22% of a program’s value over thenext few years, in line with those of Oracle,its main rival.

Yet the biggest challenge for software�rms is to become providers of online ser­vices themselves, says Brent Thill of Citi In­vestment Research. So far they havemoved slowly, o�ering SaaS only on theside, if at all. This was partly because theircustomers were not that keen. But moreimportantly, notes Mr Thill, the softwarehouses are still wedded to their old busi­ness model. With SaaS they do not get a bigupfront payment, only subscription fees.

Once Salesforce and NetSuite hadshown that the SaaS model works, the in­cumbents began to move faster. In Septem­ber last year, for instance, SAP presented�Business ByDesign�, a package of web­based enterprise applications for smallerbusinesses. But success will not come easi­ly. SAP has slowed down the introductionof the new service because it still needs towork out how to run it cheaply enough tomake a reasonable pro�t.

Pure SaaS providers also have a lot ontheir minds. Some experts, such as JoshuaGreenbaum of Enterprise ApplicationsConsulting, reckon that few will ever be aspro�table as traditional software �rms. Al­though it is almost a decade old, Salesforcestarted making money only in 2006, main­ly because it �rst had to spend heavily onmarketing to attract customers. But nowthat the service has 1m users and revenuesof more than $1 billion, these costs willcome down, says the �rm.

The companies that have the bestchance of making money from the cloudare those that get things to connect and

work together and help customers movetheir computing around. This is music tothe ears of big IT �rms, not least IBM. Near­ly 80% of its revenues come from infra­structure software and IT services, which itcan o�er globally. HP is catching up, havingtaken over EDS, another big IT­services�rm. Both Microsoft and SAP, for their part,believe that �rms will want to have achoice in where to do their computing, aswell as the �exibility to move thingsaround over time.

Two potentially important contestantsare rarely mentioned: Cisco and EMC, theleading makers of networking and storagegear respectively. Having invested a lot insoftware and services, Cisco has becomemore than just the source of most of theworld’s routers, the tra�c cops of the inter­net. It is betting that in the cloud the net­work layer will become more important,for instance to ensure that computingworkloads are able to move around se­curely. EMC, for its part, has made two doz­en cloud­related investments andlaunched a cloud­infrastructure division.

Whoever manages to own the domi­nant operating system for the data centrecould become a big winner. VMware isbound to have a shot at this. As well as be­ing the market leader in virtualisation, ithas the support of EMC, which holds 86%of the �rm. But the competition is likely tobe intense.

Will this prospective platform war pro­duce a dominant company in the mould ofIBM or Microsoft that is able to extractmore than its fair share of the pro�ts? Prob­ably not, because it will be relatively easyto switch between vendors, says GeorgeGilbert of Tech Strategy Partners, a consul­tancy. Nor is it likely that one �rm willmanage to build a global cloud monopoly.Although there are important economiesof scale in building a network of data cen­

�BUSINESSES, as well as most organi­sations outside the business world,

begin to shift from hierarchical processesto networked ones. Nearly every facet ofhuman activity is transformed in someway by the emergent fabric of interconnec­tion. This reorganisation leads to dramaticimprovements in e�ciency and produc­tivity.� So said Wired magazine, the centralorgan of Web 1.0, in July 1997 in an essay en­titled �The Long Boom�, arguing that theworld was in for �25 years of prosperity,freedom and a better environment�. Backthen, the article re�ected the general opti­

mism that led up to the internet bubble.Now, after two busts, several wars andgrowing fears of global warming, it makesfor somewhat surreal reading.

The cloud lends itself to similar hyper­bole. Yet so far there has not been much de­bate about its economic fallout�probablybecause the �new economy� ended badlyand the newest one is currently doing evenworse. There will be many ways in whichthe cloud will change businesses and theeconomy, most of them hard to predict, butone theme is already emerging. Businessesare becoming more like the technology it­

self: more adaptable, more interwovenand more specialised. These develop­ments may not be new, but cloud comput­ing will speed them up.

Corporate IT has always promised tomake companies more agile. In the 1990smany companies re­engineered their busi­ness processes when they started using aform of software called enterprise­re­source planning (ERP), which does thingssuch as managing a �rm’s �nances andemployees. But once these massive soft­ware packages were in place, it was exceed­ingly di�cult to change them. Implement­

The long nimbus

The cloud will make businesses more adaptable, interconnected and specialised�and often smaller

tres, the computing needs of companiesand consumers vary too widely for onesize to �t all.

Even if the cloud is likely to transformthe IT industry, some things will stay thesame. One is the importance of lock­in. Ifanything, companies and developers willbe even more dependent on cloud plat­forms and applications than they are onthe old kind. SaaS promotes the �hollow­ing out� of IT: a �rm that needs to migrateto another system will no longer have therequired expertise. When Facebook, say,makes a change to its platform, developershave no choice but to go along with it.Some are already calling for a �CloudComputing Consortium�, in the mould ofthe World Wide Web Consortium (W3C),to set standards that allow applications tomigrate easily from one platform to anoth­er. One standard initiative, called �Open­Social�, already allows the same web­based application to run in several socialnetworks, which are also clouds of sorts.

But standards go only so far. Some fearthat one company could try to monopoliseother key parts of the cloud; ironically, Mi­crosoft worries that Google is doing exact­ly that with the online advertising market.To Steve Ballmer, Microsoft’s boss, Goo­gle’s advertising platform is like a �ywheelthat picks up speed as more websites at­tract more advertisers, and vice versa.

Eric Schmidt, Google’s chief executive,denies any evil intent to achieve worlddomination. He argues, with some justice,that it would be hard for Google to controlthe cloud, if only for technical reasons:much of it is already based on open stan­

dards, and its loose structure does not lenditself to locking customers in.

Mr Schmidt promises that Google willnot lock its users in either. �Our competi­tive advantage is not from lock­in�, he says,�but from having specialised knowledgeof how to build data centres and how tobuild new software that is not reproduc­ible, such as our search algorithm. This ishow we make our money.�

Yet Google is more like Microsoft than itlikes to admit, says Nicholas Carr, a tech­nology writer and blogger. Microsoft, heargues, achieved its dominant position inthe PC world not least by commoditising

products, such as the browser, that arecomplementary to its cash cows, such asWindows: as their cost came down, de­mand for Microsoft’s products went up.

Similarly, Google’s natural instinct is todo its utmost to encourage people to spendmore time online, because that will givethe company more opportunities to selladvertisements and collect data aboutthem. According to Mr Carr, almost every­thing the company does�building hugedata centres, �ghting copyright restrictions,digitising the world’s libraries, developinga new browser and, most recently, evenhelping to launch satellites�is aimed at in­creasing the use of the internet. �Googlewants information to be free�, he recentlywrote in his blog, �because as the cost of in­formation falls it makes more money.�

But Google may never become as pow­erful as Microsoft because regulators areunlikely to let it. Microsoft was eventuallyput in the dock for abusing its monopolybecause it got too greedy, pushing most ofthe rest of the industry to complain. Giventhat the world has already lived throughthe Microsoft drama and that Google willa�ect many more industries, the searchcompany is likely to be restrained muchearlier. The �rm is currently in negotiationswith the US Justice Department about acontroversial advertising partnership be­tween itself and one of its competitors, Ya­hoo!, which would further strengthenGoogle’s position in online advertising.

Even if the economics of the cloud arestill in �ux, though, it is already clear that itwill have far­reaching implications forbusinesses and for society as a whole. 7

ing SAP, the market leader in ERP, is likepouring concrete into your company, goesan old joke among IT types.

This helps to explain why in many�rms IT departments and business unitshave traditionally been at loggerheads. Inrecent years tensions have worsened.Companies must grapple with ever­chang­ing markets and regulations, yet IT budgetsare being cut. Many �rms now have a hugebacklog of IT projects.

Hence the interest in cloud computing.It turns capital expenditure into operation­al expenditure, which makes things mucheasier and cheaper. Instead of having toshell out a lot of money for, say, a server totest an application and, even with luck,wait a few weeks for it to be up and run­ning, managers just have to whip out acredit card, open an account at AmazonWeb Services (AWS) and �re up a virtualmachine for a few dollars.

In many �rms senior managers proba­bly do not even know that business unitsare using AWS or similar services. In someorganisations, however, it has already be­come a much­appreciated R&D tool. Phar­maceutical companies, for instance, areregularly tapping into AWS to calculatesimulations. Sogeti, a European consultan­cy, has used a cloud built by IBM to allow itto test new ideas and quickly put togetheran IT system for a company­wide brain­storming event.

Cloud services have also been hugelysuccessful with start­ups, which can nowenjoy infrastructure of the same quality aslarge companies. In fact, AWS is probablythe main reason why there are now somany �rms o�ering all kinds of �Web 2.0�services. Their usefulness may sometimesbe hard to gauge, but that is a good thing. Itis a sign of lively �combinatorial innova­tion�, made possible because entrepre­neurs can cheaply try new combinationsof technology, says Google’s Mr Varian.

Many start­ups would probably noteven exist without the cloud. Take Ani­moto, a service that lets users turn photosinto artsy music videos using arti�cial in­telligence. When it launched on Facebook,a social network, demand was such that ithad to increase the number of its virtualmachines on AWS from 50 to 3,500 withinthree days. �You could give me unlimitedfunding,� says Adam Selipsky of AWS,�and I wouldn’t know how to deploy thatmany servers in 72 hours.�

Combinatorial innovation should alsobe made easier by the fact that the cloudwill be a huge collection of electronic ser­vices based on standards. But this service­

oriented architecture will be even moreimportant for existing �rms because itshould free their inner workings�their�business processes��from the straitjacketof their ERP systems and allow these pro­cesses to be more easily adapted, for in­stance to launch a new product.

Again, the software industry has beenpromising this for some years under thebanner of service­oriented architecture,discussed in an earlier chapter. Yet theadoption of SOA has been slow and manyprojects have failed, says Chris Howard ofthe Burton Group, a consultancy. The rea­sons are not just technical but cultural; forexample, some business units are not usedto sharing data. Cloud computing will helpresolve some of these problems. Manyweb­based services are built to be integrat­ed into existing business processes.

Don’t do it yourselfWhat e�ect will all this have on the natureof the �rm? If IT systems really allow com­panies to become more modular and �ex­ible, this should foster further specialisa­tion. It will become even easier tooutsource business processes, or at leastthose parts of them where �rms do not en­joy a competitive advantage. Companieswill increasingly focus on their �core� andshed the �context�, in the words of Geof­frey Moore, managing director of TCG Ad­

visors, a consultancy.This also means that companies will

rely more on services provided by others.They will increasingly form �process net­works�, a term for loosely connectedgroupings of specialised �rms coined byJohn Hagel, a business strategist at Deloitte& Touche, an auditing �rm. His prime ex­ample is Li & Fung, a company based inHong Kong that has assembled a globalprocess network of nearly 10,000 businesspartners in the clothing industry fromwhich it puts together customised supplychains for clothes designers.

Both trends could mean that in futurehuge clouds�which might be called �in­dustry operating systems��will providebasic services for a particular sector, for in­stance �nance or logistics. On top of thesesystems will sit many specialised and in­terconnected �rms, just like applicationson a computing platform. Yet this is onlyhalf the story. The cloud changes not onlythe plumbing and structure of �rms andindustries, known as the �transactionallayer�, but also their �interactional layer�,a term coined by Andy Mulholland, chieftechnologist of Capgemini, a consultancy.He de�nes this as the environment whereall the interactions between people takeplace, both within an organisation andwith its business partners.

READERS may be excused if they havenever heard of Kinakuta. It is a tiny is­

land dreamed up by Neal Stephenson inhis novel �Cryptonomicon�. In the sci­ence­�ction classic, libertarian technolo­gists and entrepreneurs try to turn it into adata haven for such things as anonymousonline banking and electronic money.

Reality has indeed caught up with fan­tasy. Iceland is about to become a Kinakuta

of sorts. Data Islandia, a local company, istrying to establish the island as a vault for agrowing pile of data that �rms must retainin order to comply with all kinds of regula­tions. It has a compelling pitch. With itscool climate, abundant geothermal energyand secure remoteness, Iceland appears tobe a prime location for data archives.

As often, however, truth is strangerthan �ction. In a way, Data Islandia is erect­

ing borders in the cloud: it intends to storeEuropean data according to European reg­ulation and American bits according toAmerican rules. What is more, to keep thedata safe during transport, they are pickedup with a �data scooter� (in essence a con­tainer �lled with disk drives) and taken toIceland by aeroplane�as though �bre­op­tic links had never been invented.

This illustrates the political tensions

Computers without borders

The cloud may be the ultimate form of globalisation

tered the workplace in recent years, so farthis layer has not really changed. PCs cer­tainly made people more productive, butmost of their programs were not designedfor collaboration. The enterprise applica­tions they worked with were still central­ised systems. And e­mail has in some waysmade things worse as the �ood of mes­sages takes up lots of time and attention.

The dominant model is still that people�rst labour individually and then mergetheir respective e�orts, says Mr Mulhol­land. �It’s not much di�erent from the ageof paper,� he writes in his book �Mesh Col­laboration�. �Collaboration often meanspulling up your chair next to your col­league so you can look at the same screen.�

Consumers have pulled ahead of com­panies in using cloud­based services thatallow for better collaboration, such asblogs, wikis and social networks. The �rstgeneration of people that has grown up us­ing all these tools is now entering theworkforce. Being used to a culture of shar­ing information freely, these �digital na­tives� will be impatient with the rules oftraditional corporate IT.

So it is helpful that �rms have at last be­gun to embrace Web 2.0 technologies inearnest, a trend predictably called Enter­prise 2.0. By 2013 companies around theglobe will spend $4.6 billion on such tools,according to Forrester Research. What no­body knows is how �rms will trade o� theadvantages of letting employees collabo­rate with the outside world against the as­sociated risks, for instance that con�den­tial information is leaked. Because of suchsecurity concerns (see chart 8), many �rmsblock access to such sites as Facebook oncompany computers.

Companies may not have much choicebut to open up, says Mr Mulholland. Em­

ployees will increasingly resist constraintson their use of technology, and they willhave a growing need to reach beyond thecorporate �rewall. Twenty years ago, he ar­gues, 80% of the knowledge that workersrequired to do their jobs resided withintheir company. Now it is only 20% becausethe world is changing ever faster. �We needto be open to new and unknown connec­tions with people and content,� he says.

Exploiting the �mesh�, in the words ofMr Mulholland, will also mean that em­ployees may build simple applications oftheir own that allow them quickly to auto­mate repeat tasks, using internal and exter­nal IT services. A new product by SerenaSoftware called Mashup Composer gives aforetaste of things to come. Using a visualinterface, even the not so technically mind­ed can quickly put together a service todeal, say, with travel requests or approvedocuments.

Yet the impact of the cloud will also befelt on a macroeconomic level. Just as itmakes small �rms more competitive, itwill help developing economies to move

ahead. �The biggest promise is that it willmake computing cheaper and easier touse�and thus allow it to penetrate newmarkets,� says Russ Daniels, chief technol­ogy o�cer for HP’s cloud­services strategy.

Hop, skip and jumpThe mobile phone has already enabled de­veloping countries to skip �xed­line net­works. Cloud computing could prove to bea similar �leapfrog� technology because itdispenses with the need to build a cumber­some IT infrastructure. �Software develop­ers from a developing country can buildjust as great an application on our platformas somebody who lives in Palo Alto,� saysMr Benio� of Salesforce.

Indeed, countries such as India will cer­tainly take a big chunk of the global marketfor cloud services. Zoho, a popular suite ofweb­based applications, is operated by anIndian company, AdventNet. Indian hospi­tals are already o�ering specialised health­care services this way. The insurance armof ICICI, an Indian bank, has used thetechnology to come up with innovativeservices such as a personalised insurancefor diabetes. Premiums are adjusted de­pending on how well policyholders stickto a �tness plan. All this suggests that theeconomic impact of the cloud may be feltnot only in the IT industry itself but in oth­er sectors too. The internet disrupted themusic business; Google disrupted the me­dia; cloud­based companies could becomedisrupters in other ine�cient industries.Buzzwords such as �Health Care 2.0�,�Banking 2.0� or even �Education 2.0�could soon acquire real meaning.

But given that the cloud is global by na­ture, how might it be regulated? The con­clusion of this special report will o�ersome answers. 7

that will arise with the cloud. In one way itis the ultimate form of globalisation: vastvirtualised computer systems and elec­tronic services know no borders. Yet gov­ernments are likely to go to great lengths toavoid losing even more control.

When the internet went mainstream inthe late 1990s, libertarian thinkers arguedthat cyberspace was a distinct place callingfor laws and legal institutions of its own.After all, they said, it was built in such away �that it interprets censorship as dam­age and routes around it�. But many gov­ernments quickly found ways to blockcontent they deemed o�ensive. Just look atChina and its �great �rewall�.

Controlling where data are stored andhow they are treated is harder, though, be­cause information can �oat freely in thecloud. And it is not just undemocratic gov­ernments that want to control their citi­zens’ and companies’ data: indeed thereare nearly as many sets of data regulationas there are countries. �If we wanted to beon the safe side in terms of regulation, weprobably would need 95 individual datacentres,� says Chuck Hollis, a technologistat EMC, the leading maker of storage gear,which owns Mozy, a cloud service that al­lows users to back up their data.

There are technological �xes to this pro­blem, too. Customers of Amazon’s storageservice, for instance, can have their datakept either in an American or a Europeandata centre. In future, cloud providers willo�er many more options for where dataare kept and how they are protected. Itseems possible that data as well as content

will eventually travel with security, loca­tion and expiry policies attached.

It is when computers become virtualmachines that things get really tricky.These days IT systems are at the core ofmany companies�and just like data, thesesystems can now live in a variety of places.What happens if they start to migrate toanother country where power is cheaperor regulation laxer? Similarly, if servicesare a combination of elements provided indi�erent jurisdictions, who is liable ifsomething goes wrong?

The cloud’s potential political and so­cial e�ect is only now entering the publicdebate. IT �rms are putting it on the agendaon both sides of the Atlantic. In mid­Sep­tember, for instance, Google organised adiscussion on the subject in Washington,DC. A few days later SAP presented a whitepaper in Brussels pointing out that policy­makers are not aware of the dramatic eco­nomic impact of the �Future Internet�, asthe paper calls the cloud.

IT industry leaders note that o�cialsfrom many countries have begun to takean interest in the cloud. Some just wantdata centres to be built in their country tocreate jobs; others are concerned about is­sues of law enforcement and jurisdiction.The danger, they say, is that cloud provid­ers might be obliged to build more datacentres than are needed and have to com­ply with many di�erent regulatory re­gimes. Some of them have been �oatingthe idea of �free­trade zones� for data cen­tres where common rules would apply.

Yet such ideas appear at odds with an­other big question that could keep thecloud from growing: how to protect pri­vacy. �Consumers expect their informa­

tion will be treated the same way on thecloud as if it were stored at home on theirown computers,� says Ari Schwartz of theCenter for Democracy and Technology, anadvocacy group. Many of the devices thatfeed into it, such as sensors and cameras,will be intrusive. For example, Google’svans go round taking street­by­street pic­tures of cities for the company’s onlinemap service called �Streetview�. The pic­tures are meant to help people �nd theirway around, but also often show pass­ers­by in embarrassing situations. To pro­tect their identity, Google now blurs theirfaces and licence plates.

Hands o� my dataBut it is not only personal information thatcould get out into the open. Privacy is aworry for companies too�and not just be­cause criminals or spies might intercepttheir data. Once they are in the cloud, gov­ernments can also get their hands on themmore easily. SWIFT, the organisation thatmanages international bank transfers, isplanning to build a data centre in neutralSwitzerland. That will allow it to keep dataabout European transfers on the old conti­nent, where it cannot be subpoenaed bythe American government. Web­based e­mail is not safe either. Thanks to the StoredCommunications Act, American law en­forcers can read people’s messages�anddo not even have to tell the recipient.

Just as too much regulation may keepthe cloud from rising high, so could lack ofprivacy. If consumers and companies can­not be sure that their information is safe,they will err on the side of caution. But de­spite all the caveats, the precipitation fromthe cloud will be huge. 7
