Definitions- Cloud Computing • Cloud Comp is a style of computing, where massively scalable IT related capabilities are provided ‘ as a service ’ across the Internet to multiple external customers . ….. Gartner – It means Cloud should deliver a service on a subscription basis, allow access from anywhere and provide economies of scale. – Cloud will go cross vendor and feature shared resources. Q. Is Cloud a metaphor for the Internet? • Cloud computing is an evolution of the Internet computing or usage of the Internet as a computing infrastructure & resource. CC is used to provide services such as Data Storage, Software Applications, and email and file exchanges • CC is Ubiquitous network access • CC promised infinite elastic computing resources. 19 Oct 2013 Trends Cloud Comp- NKN WS 2013 4
