What is cloud computing?
The "cloud" is another word for the internet.
It is the process of taking the services and
tasks performed by our computers and bringing
them to the web.
The most common analogy to explain cloud
computing is that of public utilities such as
electricity, gas, and water. Just as standardized
utilities free individuals from the difficulties
of generating electricity or pumping water, cloud
computing frees users from certain hardware and
software installation and maintenance tasks

How Cloud Computing Works...
4
What does this mean to us?
With the "cloud" doing most of the work, this
frees us up to access the "cloud" however we
choose. It could be a super-charged desktop PC
designed for high-end gaming, or a "thin client"
laptop running the Linux operating system with an
8 gig flash drive instead of a conventional hard
drive, or even an iPhone or a Blackberry.
5
You can work or play anywhere.....
We can also get at the same information and
perform the same tasks whether we are at work, at
home, or even a friend's house. Not that you
would want to take a break between rounds of
Texas Hold'em to do some work for the office --
but the prospect of being able to do it is pretty
cool.

  The two most significant components of cloud
computing architecture are known as the front end
and the back end. The front end is the part seen
by the client, i.e. the computer user. This
includes the clients network (or computer) and
the applications used to access the cloud via a
user interface such as a web browser. The back
end of the cloud computing architecture is the
cloud itself, comprising various computers,
servers and data storage devices.

A simple example of cloud computing is Yahoo
email or Gmail etc. You dont need a software or a
server to use them. All a consumer would need is
just an internet connection and you can start
sending emails. The server and email management
software is all on the cloud ( internet) and is
totally managed by the cloud service provider
Yahoo , Google etc. The consumer gets to use the
software alone and enjoy the benefits. The
analogy is , 'If you only need milk , would you
buy a cow ?' All the users or consumers need is
to get the benefits of using the software or
hardware of the computer like sending emails etc.
Just to get this benefit (milk) why should a
consumer buy a (cow) software /hardware ?
