Cloud Computing :
Cloud computing simply means sharing computing resources over the network. Cloud computing means the ability to run an application over many connected computers at the same time.

means "a type of Internet-based computing," where different services --
such as servers, storage and applications -- are delivered to an
organization's computers and devices through the Internet.
