CLOUD COMPUTING - OVERVIEW, APPLICATIONS, ISSUES AND CHALLENGES

摘要

A Cloud is an Internet based computing environment where we pay only for the resources that we use just like we pay the electricity and water supply bill. Cloud computing is a marketing term for technologies that provide computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. A parallel to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand the component devices or infrastructure required to provide the service.
