Cloud Computing

Suppose  in a  software company some ‘XYZ’ employee’s  particular responsibility include, making sure that all of the company’s  employees have the right hardware and software ,which is required to get their job done.

 Buying just computers for everyone isn't enough -- but have to purchase software or software licenses to give employees the tools they need. Whenever there is  a new joinee, company needs to buy more software or make sure current software license allows another user, this becomes a tedious job.

Now here is something which can make change in the scenario.

Rather than installing a suite of software for each computer, just load one application. That application would allow users to log into a Web-based service which hosts all the programs the user would need for his or her job. Remote machines owned by another company would run everything , from e-mail to word processing and complex data analysis programs. This is cloud computing and it could change the entire computer industry.

In a cloud computing system, there's a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Important thing to mention is, hardware and software demands on the user's side decrease. The only thing the user's computer needs to be able to run is the cloud computing system's interface software, which can be as simple as a Web browser, and the cloud's network takes care of the rest.

You've had some experience with cloud computing ,as we generally have an e-mail account on Gmail,Yahoo or Hotmail. So  Instead of running an e-mail program on your computer, we log in to e-mail account. The software and storage for your account doesn't exist on your computer -- it's on the service's computer cloud.

So in Short, the companies don't have to buy a set of software or software licenses for every employee. Instead, the company could pay a metered fee to a cloud computing company. In future ,IT needs will be reduced ,if  companies switch to using streamlined computer systems.
