Cloud is a platform providing dynamic resource pools, virtualization & high availability. It‟s the concept implemented to overcome our regular computing problem like hardware software resource availability and related aspects. Cloud computing makes it easy to have high performance computing. Cloud computing is a service which is easily available on market when you want it you can start the service and when you don't want you stop the service and you pay it for what you use, you need a computer or a laptop to access the Cloud Services.Cloud services are becoming popular in terms of distributed technology because they allow cloud users to rent well-specified resources of computing, network, and storage infrastructure.
