Cloud computing refers to an on-demand, self-service Internet infrastructure that enables the user to access computing resources anytime from anywhere . It is a new model of delivering computing resources, not a new technology. When the cloud server is overloaded, the situation becomes critical, in such case to provide the effective service to the client, the process migration is done. Cloud migration is the process of moving data, applications or other business elements from an organization's onsite computers to the cloud, or moving them from one cloud environment to another and to perform the effective execution of cloud requests.
