In simple words, Cloud computing is a service that lets you use any computing
service such as a server, storage, networking, databases, and intelligence, 
right through your browser without owning anything. You can do anything you 
can think of unless it doesn’t require you to stay close to your hardware to 
use it like you can’t do document scanning or printing because it requires you
