Lately, an expression known by the name

CloudComputing started to be familiar

to most of us. But, has anyone of us know

what really that expression is all about,

this is what we are going to know through

this article.

Cloud computing is a type of computing

that relies on sharing computing resources

rather than having local servers or

personal devices to handle applications.

In cloud computing, the word cloud (alsophrased as "the cloud") is used as a

metaphor for "the Internet," so the phrase

cloud computing means "a type of

Internet-based computing," where

different services such as servers, storage

and applications are delivered to

organizational computers and devices

through the Internet.

Cloud computing is comparable to gridcomputing, a type of computing where

unused processing cycles of all computers

in a network are harnesses to solve

problems too intensive for any stand-alone

machine.

The goal of cloud computing is to apply

traditional supercomputing, or high-

performance computing power, normally

used by military and research facilities, to

perform tens of trillions of computations

per second, in consumer-oriented

applications such as financial portfolios, to

deliver personalized information, to

provide data storage or to power large,

immersive computer games.

Traditional business applications have always been very complicated and expensive. The

amount and variety of hardware and software required to run them are daunting. You

need a whole team of experts to install, configure, test, run, secure, and update them.

When you multiply these efforts across dozens or hundreds of apps, its easy to see why

the biggest companies with the best IT departments arent getting the apps they need.

Small and mid-sized businesses dont stand a chance.

How does this work, Cloud computinguses networks of large groups of servers.

Typically, these servers are running low-

cost consumer PC technology with

specialized connections to spread data-

processing chores across them. This

shared IT infrastructure contains large

pools of systems that are linked together.

Often, virtualization techniques are used

to maximize the power of cloud computing.

The standards for connecting the

computer systems and the software

needed to make cloud computing work are

not fully defined at present time, leaving

many companies to define their own cloud

computing technologies. Cloud computing

systems offered by companies, like IBM's

"Blue Cloud" technologies for example, are

based on open standards and open source

software which link together computersthat are used to deliver Web 2.0

capabilities like mash-ups or mobile

commerce.

Cloud computing has started to obtain

mass appeal in corporate data centers as it

enables the data center to operate like the

Internet through the process of enabling

computing resources to be accessed and

shared as virtual resources in a secureand scalable manner.

For a Small& Medium size Businesses

(SMB), the benefits of cloud computing is

currently driving adoption. In the SMB

sector there is often a lack of time and

financial resources to purchase, deploy

and maintain an infrastructure (e.g.

software, server and storage).

In cloud computing, small businesses can

access these resources and expand or

shrink services as business needs change.

The common pay-as-you-go subscription

model is designed to let SMBs easily add

or remove services and you typically will

only pay for what you do use.

Cloud computing requires searching for a

cloud provider whether your cloud is

public, private, or hybrid; youd better

Look for elasticity, scalability,provisioning, standardization, and billed

usage; elasticity and scalability. The cloud

is elastic, meaning that resource allocation

can get bigger or smaller depending on

demand. Elasticity enables scalability,

which means that the cloud can scale

upward for peak demand and downward

for lighter demand. Scalability also means

that an application can scale when addingusers and when application requirements

change; Self-service provisioning. Cloud

customers can provision cloud services

without going through a lengthy process.

You request an amount of computing,

storage, software, process, or more from

the service provider. After you use these

resources, they can be automatically

deprovisioned; Standardized interfaces.

Cloud services should have standardized

APIs, which provide instructions on how

two application or data sources can

communicate with each other. A

standardized interface lets the customer

more easily link cloud services together;

billing and service usage metering. You

can be billed for resources as you use

them. This pay-as-you-go model means

usage is metered and you pay only forwhat you consume. Besides, cloud

computing has offered us a lot of benefits

like: Decreased Costs where the Cloud

you consume. Besides, cloud computing

has offered us a lot of benefits like:

Decreased Costs where the Cloud

eliminates the need for each user to invest

in stand-alone servers or software that is

capital intensive, but under-utilized most

of the time. As technological innovations

take place, these resources become

obsolete and must be replaced with the

latest in order to ensure operational

efficiency requiring more capital

investment and the cycle repeats. The

Cloud eliminates the need for suchreplacement capital expenditure;

Innovation in which enterprises can focus

on innovation, as they do not have to own

or manage resources. Cloud computing

facilitates faster prototype development,

testing and validation; Location

Independence in which service providers

can set up infrastructure in areas with

lower overheads and pass on the benefit;Optimal Resource Utilization where

servers, storage and network resources

are better utilized as the Cloud is shared

by multiple users, thus cutting down on

waste at a global level. Cloud computing is

more environment-friendly and energy

efficient; Flexibility where users can opt

out at will and thus gain a high level of

operational flexibility; Device

Independence in which applications

provided through the Cloud can be

accessed from any device a computer, a

smartphone, an iPad, etc.

So, to summarize, the cloud computing is

a culmination of numerous attempts at

large scale computing with seamless

access to virtually limitless resources,

although its considered as a new

technology that encounters our technicalcommunity, it become an essential part in

our daily lives.
