World of Cloud Computing & Security

Abstract

Cloud computing promises to increase the velocity with which application are deployed, increase innovation and lower costs, all while increasing business agility and hence envisioned as the next generation architecture of IT Enterprise. Nature of cloud computing builds an established trend for driving cost out of the delivery of services while increasing the speed and agility with which services are deployed. Cloud Computing incorporates virtualization, on demand deployment, Internet delivery of services and open source software .From another perspective, everything is new because cloud computing changes how we invent, develop, deploy, scale, update, maintain and pay for application and the infrastructure on which they run. Because of these benefits of Cloud Computing, it requires an effective and flexible dynamic security scheme to ensure the correctness of users‟ data in the cloud. Quality of service is an important aspect and hence, extensive cloud data security and performance is required.
