Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network.
Cloud computing provides computation, software applications, data access,data management and storage resources without requiring cloud users to know the location and other details of the computing infrastructure.
End users access cloud based applications through a web browser or a light weight desktop or mobile app while the business software and data are stored on servers at a remote location.
Cloud application providers strive to give the same or better service and performance than if the software programs were installed locally on end-user computers.
