A Survey Paper on Improving Performance and Enhancing Security by Using Division and Replication of Data in Cloud

Abstract

Abstract:Cloud computing is an information technology paradigm model which offers clients access to shared pool of resources. Replication and division of data takes into consideration the performance and security issues. A given file is divided into fragments and then replicated. They are placed over the nodes (servers) and every node stores a single fragment of data in order to improve security. The nodes that store the replicas and fragments are not adjacent to each other by applying T-coloring method hence preventing the attacker from gaining access to useful information. The user can download the file from anywhere but has to specify the exact location as well as the time and date in order to get maximum security as compared to other systems. The likelihood of finding andcompromising the nodes that store the fragments of a file is very low.
