Abstract:

This paper describes cloud computing, a computing platform for the next

generation of the internet. The paper defines clouds, explains the business benefits of cloud

computing, and outlines cloud architecture and its major components. It will discover how

a business can use cloud computing to foster innovation and reduce IT costs.

INTRODUCTION:

With traditional desktop

computing, we run copies of

software programs on our own

computer. The documents we

create are stored on our own pc.

Although documents can be

accessed from other computers onthe network, they can t be accessed

by computers outside the network.

This is PC-centric.

With cloud computing, the

software programs one use are not

run from ones personal computer,

but are rather stored on servers

accessed via the Internet

If a computer crashes, the software

is still available for others to use.

Same goes for the documents one

create; they are stored on a

collection of servers accessed via

the Internet.

Anyone with permission can not

only access the documents, but can

also edit and collaborate on those

documents in real time.

Unlike traditional computing, this cloud

computing model is not PC-centric, it is

document-centric.

What Is Cloud

Computing?

Key to the definition of cloud

computing is the cloud itself.

Here, the cloud is a large group of

interconnected computers.

These computers can be personal

computers or network servers;they can be public or private.

This cloud of computers extends

beyond a single company or

enterprise. The applications and

data served by the cloud are

available to broad group of users,

cross-enterprise and cross-

platform.

Access is via the Internet. Anyauthorized user can access these docs

and apps from any computer over

any Internet connection.

Advanced clouds typically

include other computing resources

such as storage area networks (SANs),

network equipment, firewall and

other security devices.

These cloud applications use large datacenters and powerful servers that host

Web applications and Web services.

Anyone with a suitable Internet

connection and a standard

browser can access a cloud application.

VENDORS OF CLOUD COMPUTING:

Key properties of cloud computing:

Cloud Computing Is User Centric :

Once the users are connected to the

cloud, whatever is stored there

documents, messages, images,

applications, whatever becomes

authorized to the user access them. In

addition, not only is the data, but one

can also share it with others. In

effect, any device that accesses your

data in the cloud also becomes yours.

Cloud Computing Is

Task-Centric

Instead of focusing on the application

and what it can do, the focus is on

what one need done and how the

application can do it for us.

Traditional applications word

processing, spreadsheets, email, and

so on are becoming less important

than the documents they create.

Cloud Computing IsPowerful:

Connecting hundreds or

thousands of computers together in a

cloud creates a wealth of computing

power impossible with a single

desktop PC.

Cloud Computing Is

Accessible:Because data is stored in

the cloud, users can instantly retrieve

more information from multiple

repositories. We are not limited to a

single source of data, as we do with a

desktop PC.

Cloud Computing Is

Intelligent:

With all the various data

stored on the computers in a cloud,

data mining and analysis are

necessary to access that information

in an intelligent manner.

Cloud Computing Is

Programmable:Many of the tasks

necessary with cloud computing must

be automated. For example, to

protect the integrity of the data,

information stored on a single

computer in the cloud must be


4/7

replicated on other computers in the

cloud. If that one computer goes

offline, the clouds programming

automatically redistributes that

computers data to a new computer in

the cloud.

ECONOMIC CLOUD

COMPUTING

Diagram showing economics of cloud

computing versus traditional IT,

including capital expenditure (capex)

and operational expenditure (Opex)

Cloud computing users can avoid

capital expenditure (CapEx) on

hardware, software, and serviceswhen they pay a provider only for

what they use. Consumption is

usually billed on a utility (e.g.

resources consumed, like electricity)

or subscription (e.g. time based, like

a newspaper) basis with little or no

upfront cost. A few cloud providers

are now beginning to offer the service

for a flat monthly fee as opposed to

on a utility billing basis. Other

benefits of this time sharing styleapproach are low barriers to entry,

shared infrastructure and costs, low

management overhead, and

immediate access to a broad range of

applications. Users can generally

terminate the contract at any time

(thereby avoiding return on

investment risk and uncertainty) and

the services are often covered by

service level agreements (SLAs) with

financial penalties

How Cloud Computing

Works?

Sun Microsystems slogan is The

network is the computer, and that as good

as any to describe how cloud computingworks. In essence, a network of

computers functions as a single computer

to serve data and applications to users

over the Internet. The network exists in

the cloud of IP addresses that we know as

the Internet, offers massive computing

power and storage

Components of cloud

computing :

Understanding Cloud

Architecture:

Individual users connect

to the cloud from their own personal

computers or portable devices, overthe Internet. To these individual

users, the cloud is seen as a single

application, device, or document. The

hardware in the cloud (and the

operating system that manages the

hardware connections) is invisible.

It all starts with the front-end

interface seen by individual users.

This is how users select a task or

service (either starting an applicationor opening a document). The user

request then gets passed to the system

management, which finds the correct

resources and then calls the system

appropriate provisioning services.

Architecture

These services carve out thenecessary resources in the cloud,

launch the appropriate web

application, and either creates or

opens the requested document. After

the web application is launched, the

system monitoring and metering

functions track the usage of the cloud

so that resources are apportioned

and attributed to the proper user(s).

Understanding CloudStorage:

One of the primary uses

of cloud computing is for data

storage. With cloud storage, data is

stored on multiple third-party

servers, rather than on the dedicated

servers used in traditional networked

data storage. When storing data, the

user sees a virtual server that is, it

appears as if the data is stored in aparticular place with a specific name.

But that place does not

exist in reality. It is just a pseudonym

used to reference virtual space

carved out of the cloud. In reality, the

users data could be stored on any one


6/7

or more of the computers used to

create the cloud.

Understanding Cloud

Services:

Any web-based application

or service offered via cloud

computing is called a cloud service.

Cloud services can include anything

from calendar and contact

applications to word processing and

presentations.

With a cloud service, the

application itself is hosted in the

cloud. An individual user runs theapplication over the Internet,

typically within a web browser.

The browser accesses the

cloud service and an instance of the

application is opened within the

browser window. Once launched, the

web-based application operates and

behaves like a standard desktop

application.

Cloud computinginfrastructure allows

enterprises to achieve more

efficient use of their IT

Hardware and software

investments:Cloud computing increases

profitability by improving resource

utilization. Pooling resources into largeclouds drives down costs and increases

utilization by delivering resources only

for as long as those resources are needed.

Cloud computing allows individuals,

teams, and organizations to streamline

procurement processes and eliminate the

need to duplicate certain computer

administrative skills related to setup,

configuration, and support.

Benefits from cloudcomputing

Collaborators: The ability toshare and edit documents in real

time between multiple users is one

of the primary benefits of web-

based applications; it makes

collaborating easy and even fun.

Road Warriors: you can access

a single version of your documentfrom any location.

Cost- Conscious users:Another group of users who

should gravitate to cloud

computing are those who are cost

conscious. With cloud computing

you can save money on both your

hardware and software.

e-business:

In e-business, scalability can be

achieved by making new servers

available as needed. For example,

during a peak shopping season,

more virtual servers can be made

available that can cater to high

shopper demand. In another

example a company mayexperience high workloads on

weekends or evenings as opposed

to early mornings and weekdays.

If a company has a significantly

large cloud, they could schedule

computer resources to be

provisioned each evening,


7/7

weekend, or during a peak season.

There are more opportunities to

achieve efficiencies as the cloud

grows. Another aspect of this

scenario involves employing

business policies to decide whatapplications receive higher

priorities and thus more

computing resources. Revenue

generating applications may be

rated higher than research and

development or innovation pilots.

Piloting innovations on a

cloud:By combining cloud computing

and Innovation Factory, or any other

innovation platform already in use, a

company can benefit from a complete

solution that provides both physical

computer resources and an innovation

process combined with collaboration

tools. Adding cloud computing to a

companys existing innovation process

reduces the time needed to developand deliver a product, reduces the

barrier to entry, and reduces costs

associated with procurement, setup,

management, and reuse of physical

assets. Cloud computing should be

part of every innovation process when

physical or virtual computer resources

are needed for innovation pilots.

Conclusion:

Thus cloud computing provide a

super-computing power .This cloud

of computers extends beyond a single

company or enterprise. The

applications and data served by the

cloud are available to broad group ofusers, cross-enterprise and cross-

platform. It comprises an automatedframework that can deliver standardized

services quickly and cheaply.
