Secure Load Rebalancing in Cloud Environment

This paper examines the load rebalancing problem in cloud computing. The main objective of the paper is to Enhance distributed load rebalancing algorithm to cope with the load imbalance factor, movement cost, and algorithmic overhead. The load rebalance algorithm is compared against a centralized approach in a production system and the performance of the proposal implemented in the Hadoop distributed file system for cloud computing applications. We investigate to implement security provided for cloud computing and Evaluate the Quality of Service-QOS (Ex. Response Time) of whole system. In cloud computing one server controls number of sub servers, files, it can add, delete, and append dynamically. Any file sharing (uploading or downloading) are stored in sub servers and retrieved from sub servers. Before uploading and downloading that files are stored in encrypted format and retrieve in a decrypted format. In our implementation the key is sent to the user-s email id, user uses that key to view and download the files from sub server. For encryption and decryption schemes we are using RSA algorithm
