High Traffic?                Adding “servers” is a click away.                Running in just minutes, not days

Expect your Cloud  Network  is always up
Yes, you can even pick   where your data  and “servers” reside
Business Contraction? Just reduce your computing power, storage
Wait,What is the catch?
Cloud Computing   is relatively new technology

Only a handful of major players           can build this massive infrastructure
