Cloud computing is the emerging technology that has been used in recent applications. Data has been stored on the cloud servers so that this can be managed from remote locations. In the process of cloud computing various users transmit their requests for access to cloud data that has been processed at different servers. In this process a number of requests have been issued on cloud server. Various job scheduling algorithms have been proposed so that request can be respond in minimum time span. In this paper various approaches of cloud computing has been discussed so that approaches can be used for data management and response by the cloud server.
