Cloud computing is the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing. Whether you run applications that share photos to millions of mobile users or deliver services that support the critical operations of your business, the cloud provides rapid access to flexible and low-cost IT resources. With cloud computing, you don’t need to make large up-front investments in hardware and spend a lot of time managing that hardware. Instead, you can provision exactly the right type and size of computing resources you need to power your newest bright idea or operate your IT department. With cloud computing, you can access as many resources as you need, almost instantly, and only pay for what you use.
