Cloud ComputingCloud Computing
Cloud computing is a marketing term for technologies that provide computation, software, data access, and storage services.
It does not require end-user knowledge of the physical location and configuration of the system that delivers the services.

Cloud computing also is not traditional outsourcing, where a company forms out (subcontracts) its computing services to an outside firm.
While an outsourcing firm might host a company’s data or applications, those documents and programs are only accessible to the company’s employees via the company’s network, not to the entire world via the internet.
