In practice Cloud Computing is the use of a network of remote servers hosted on the Internet to store, manage,
and process data, rather than a local server or a personal computer.
In other words, cloud computing means storing and accessing data and programs over the Internet
instead of your computer's hard drive. The cloud is just a metaphor for the Internet.
All of us, either as an individual or as a company are already using the Cloud. For example, your
mobile phone service, your emails, eBay, Amazon and may other applications are already running in internet.
And when you want to access them, you have to connect to the internet using one of your gadgets.
