Storage & Transport

Sharing & Backup

I don’t use mine

(Much)

My flash disk “in the cloud”.

Cloud computing

“… lets you use files and applications over the

Internet.”

Cloud computing

“A shift in the geography of computation”

Microsoft grew during PC revolution (1980s)

Google is now doing the same, but on the internet cloud

Google’s operating system(in the cloud)

Google Docs

Google Docs Sharing

Google’s operating system(in the cloud)

Google+

Integration with search

Google is slowly integrating all these services and more…

… using the internet as a platform.

“Cloud computing is a transition, not a thing.”

Simon Wardley

…is a transition, not a thing.

http://aboutfacts.net/Else/E313/GNU/WattSteamEngine.png

A consequence of multiple factors

(Wardley)

http://www.intel.com/content/dam/intel/dm/image/homepage_images/cloud_img_1400x864.jpg

1. The concept of cloud computing

Concept Suitability Technology Attitude

John McCarthy (1960)

“…a future in which computing power and even specific applications could be sold

through the utility business model (like water or electricity).”

2. Are IT activities suitable for this transformation?

Suitability Technology AttitudeConcept

*

From novel, rare and poorly understood…

http://www.lef.csc.com/uploads/images/cloud-paper-image-004-large.png

To commonplace, more well-defined

*

As soon as one company gains some sort of technological advantage…

… then all its competitors will follow suit.

3. Do we have the technology?

Technology AttitudeConcept Suitability

Time-sharing (1960s)

Personal computing (1980s)

http://www.extremetech.com/wp-content/uploads/2011/08/ibm-pc.jpg

Personal computing (1980s)

Total control (PC) comes at a price:

1) Install / configure / update / maintain operating software

2) Same with hardware

Also… how to share information, now?

Client-server model (1980s)

Cloud computing

Why not outsource computing* to the internet?

4. Are people willing to use cloud computing?

AttitudeConcept Suitability Technology

“All organisations need to continuously evolve and adapt.”

http://51hot.net/article/UploadPic/2011-4/201141464633494.jpg

http://www.maclife.com/files/u53/clouds.jpg

Applications delivered as services over the internet

Hardware/software in data centersthat provide these services

One last example

Before I get to the bad stuff.

EbooksIn thecloud

Ebooks in libraries

Overdrive

Management of digital content for publisher, libraries, schools, and retailers. 

More than 500,000 digital titles from more than 1,000 publishers in March 2011.

http://minnesota.publicradio.org/display/web/2012/01/25/3m-ebook-cloud-library/

Ebooks in libraries

3M

Ebook collections will grow and libraries will need help managing them.

A very large opportunity as libraries shift their spend from physical material to digital material

By about 2015, a third of all books sold will be digital in the United States.

http://minnesota.publicradio.org/display/web/2012/01/25/3m-ebook-cloud-library/

Cloud computing(Library-centric)

“The broad concept of using the internet to allow people access to

technology-enabled library services”

Sounds good? Well…

If computing is moving to the internet…

... and we know the internet can be a scary place...

Risks of CC

http://1.bp.blogspot.com/-LzKhJgIscGU/TZW1IuRbKII/AAAAAAAAAj4/AMJgyr1vNcE/s1600/cloudcomputing.jpg

1. Privacy

Questions about control and ownership

Can you take your data with you? Could you lose access?Can you remove data?How does the host monitor your data?

http://cacm.acm.org/magazines/2008/7/5368-cloud-computing/fulltext

2. Security

For both provider and customer

Secure infrastructureClient data and applications protectedLiabilityIntellectual propertyEnd-of-service

3. Reliability

Internet connectivity

Network downtime

To summarise…

Cloud computing

… when computing itself moves online.… when computing becomes a utility.

Not a thing, rather a transition
