A Review on Security Concerns in Cloud Computing

The cloud computing is the technique which provides services to various users for data storage on virtual servers. In the architecture of cloud computing, it has cloud server, virtual machines, third party and virtual servers. The user can access cloud services through cloud service provider but before that user have to authenticate with the virtual machine. The user information like user credentials can be stored on the third party. The second major role of virtual machine is to provide data security to the user data. This paper mainly focuses on security concerns of cloud computing like authentication, access control, data confidentiality, integrity and availability.
