Cloud computing is an internet computing model where data is stored on servers that are on the Internet and temporarily cached on the clients' computing devices such as: desktop computers, laptops, hand-held mobile devices, etc. In a cloud computing architecture, all the applications are not stored in a company's hard disk; rather it resides in a third party computer. Cloud computing involves the supply of on-demand IT computing functions and utilities that are delivered from third party platforms as a service. On demand services and components include: software-as-a-service, platform-as-a-service, and storage-as-a-service. Cloud computing is scaling investment value with growing population and provides security for the stored information.
