Keyto the definition ofcloud computing is the cloud itself. Here , the

cloud is a large group of interconnected computers.

These computers can be personal computers or networkservers; they

can be public or private.

This cloud ofcomputers extends beyond a single companyorenterprise.

The applications and data served bythe cloud are available to broad

group ofusers, cross-enterprise and cross-platform.

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

apps from anycomputer over anyInternet connection.

keyproperties ofcloud computing:

Cloud Computing Is User Centric :

Once as a user are connected to the cloud, whatever

is stored theredocuments, 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, anydevice 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

itfor us. Traditional applicationsword processing, spreadsheets, email,

and so onare becoming less important than the documents theycreate.

Cloud Computing Is Powerful:

Connecting hundreds or thousands of computers

together in a cloud creates a wealth ofcomputing power impossiblewith a

single desktop PC.

Cloud Computing Is Accessible:

Because data is stored in the cloud, users can instantly

retrieve more information from multiplerepositories. We are not

limited to a single source ofdata, as we do with a desktop C.

Cloud Computing Is Intelligent:

With all thevarious data stored on the computers in a cloud,

data mining and analysis are necessaryto access that information in an

intelligent manner.

Cloud Computing Is rogrammable:

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 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.

How Cloud Computing Works?

Sun Microsystemss slogan is The network is the

computer, and thats as good as any to describe how cloud computing

works. 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 I addresses that w e know as the

Internet, offers massive computing power and storage capability, and

enables wide scale group collaboration.

Understanding Cloud Architecture:

Individual users connect to the cloud from their own personal

computers or portable devices, over the 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.


10/14

Understanding Cloud Storage:

One of the primaryuses ofcloud computing is for data

storage. With cloud storage, data is stored on multiple third-partyservers,

rather than on the dedicated servers used in traditional networked data

storage. When storing data, the user sees avirtual serverthat is, it appears

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

But that place doesntexist in reality. Its just a pseudonym

used to referencevirtual space carved out of the cloud. In reality, the

users data could be stored on anyone or more of the computers used to

create the cloud.

Understanding Cloud Services:

Anyweb-based application or service offered via cloud

computing is called a cloud service. Cloud services can include anythingfrom

calendar and contact applications to word processing and presentations.

With a cloud service, the application itself is hosted in the cloud.An individual userruns the application over the Internet, typicallywithin a

web browser.

The browser accesses the cloud service and an instance ofthe

application is opened within the browser window. Once launched, the web-

based application operates and behaves like a standard desktop application.

Benefits From Cloud Computing:

Collaborators:

The abilityto share and edit documents in real time between multiple users is one ofthe

primarybenefits ofweb-based applications; it makes collaboratingeasyand even fun.

Road Warriors:

you can access a singleversion ofyour documentfrom anylocation.

Cost- Consious users:

Another group ofusers who should gravitate to cloud computing are those who are cost

conscious. With cloud computingyou can save moneyon bothyour hardware and

software.

Thus cloud computing provide a super-computing

power.This cloud ofcomputers extends beyond a single

companyorenterprise.

The applications and data served bythe cloud are

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

platform.
