CLOUD COMPUTING

 

Cloud Computing, often referred to as simply “The cloud,” is the delivery of On-Demand Computing Resources — everything from applications to Data Centers — over the Internet on a pay-for-use basis.

Elastic Resources — Scale up or down quickly and easily to meet demand Metered service so you only pay for what you use Self Service — All the IT resources you need with Self-Service Access.
