In cloud computing Redistributing data to an outsider managerial control, offers ascend to security concerns. The data bargain may happen because of attacks by different users or nodes inside the cloud. Subsequently, high safety efforts are required to secure data inside the cloud. Be that as it may, the utilized security methodology should likewise consider the improvement of the data recovery time. In this paper, we propose Parting and Replication of Data for Performance and Security optimization in cloud (PRPSO) to handle the performance and security issues. In this approach, we fragment data files which are uploaded by data owner, and replication over the cloud nodes are performed. Every one of the node stores just a solitary piece of a specific data file in encrypted form that guarantees that even in an occurrence of an effective attack on a node, the data can be retrieved.
