How Does Cloud Computing Work?

Cloud computing is an Internet based computing. In cloud computing, there are hundreds of networks of servers are used to perform data processing task between them. It is somewhat like a massive IT network connecting millions of systems to make data storage and sharing easy and cost effective. In early day, this kind of computing was provided with the use of supercomputers, though it was limited to research and military organizations. The cloud is not about storing data on a home or office network. It is not a hosted service either.
