Fundamental and Comparative Study of Secure Cloud Computing

 To reduce the cost of computing, Cloud computing has now one of the booming researching areas. Currently, the services that the Cloud computing is providing to its users are on demand over the internet, hence it is very persuading technology. As it stores data and the resources are distributed in the environment, so the security of the resources and data has become the major issue that is restricting the deployment of cloud computing environments. Various users are now using the cloud to store their data, such that the security of data storage is needed in this medium of storage. The basic objective of the cloud computing environment is providing security while storing the data on server of cloud. This paper is to review various techniques of security and issues from the aspect of both software and hardware for securing data in the cloud and targeted at improving the security of data and privacy preservation for the reliable environment of cloud. In this paper, it provides an approximate analytical research of the previous researches related to the security of data and techniques of privacy preservation that are used in cloud computing.
