CLOUD COMPUTING INTRODUCTION
CLOUD COMPUTING:
Cloud computing means that instead of all the computer hardware and software you're using sitting on your desktop, or wherever inside your company's network, it provided for you as a service by another company and opened over the internet, usually in the entire whole way. Exactly where the hardware and software are located and how it all works doesn't matter to you, the user—it's just somewhere up in the unclear"cloud" that the Internet represents.

Cloud
computing is a catchword that means different things to different people. For
some, it's just another way of describing IT (information technology) "contract
out"; others use it to mean any computing service provided over the
Internet or a related network; and some define it as any bought-in computer
service you use that sits outside your firewall. However, we define cloud
computing, there's no doubt it makes the most sense when we stop talking about
abstract definitions and look at some simple, real examples—so let's do just
that.
