Cloud computing provides the capability to use computing and other storage resources which are required by various users on a metered basis and reduce the expenditure in an organization's computing infrastructure. The virtual machines running on physical hardware and being controlled by hypervisors is a cost-efficient and flexible computing technique that is used as a key technology in cloud computing and provides transparency to different cloud users as there is no actual physical allocation of the machine. As cloud computing provides various benefits nowadays, it also brings some of the concerns about the security and privacy of information. In this paper, the authors made a study about different security risks that pose a greatest threat to the cloud computing.
