Cloud Computing

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...

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.

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.

You can work or play anywhere.....

 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 client’s 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 ?
