Survey on method of encryption in cloud computing

Abstract

Cloud computing is an approach where software, hardware and other resources are provisioned as a Service. In fact Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet [9]. Cloud brings some benefits [10] such as dramatically lowers the cost of entry for smaller firms trying to benefit from compute intensive business analytics, providing an almost immediate access to hardware resources, with no upfront capital investments for users, leading to a faster time to market in many businesses, makes it easier for enterprises to scale their services, providing new classes of applications and delivers services that were not possible before.
