Redistribution of Load in Cloud Using Improved Distributed Load Balancing Algorithm with Security

R.Rajavadivu, A.Bazila Banu

In cloud computing security plays an important role. The nodes in the cloud simultaneously serve computing and storage functions. To provide security the file is partitioned into a number of chunks and are allocated in distinct. Before partitioning, the data is encrypted to provide more security. The encrypted data is then portioned and are stored in various nodes. The files are splitted dynamically on the basis of number of systems present in the cloud. In a cloud computing environment, nodes may be upgraded, replaced, and added in the system. Files in the node can be dynamically created and deleted. This results in load imbalance in a distributed file system; that is, the file chunks are not distributed as uniformly as possible among the nodes. In order to balance the load in the cloud load balancing algorithm is used. Load balancing is done by moving the chunks of the file from one system to the neighbouring system. If a node is deleted the files in the particular node is moved and stored in a balanced manner among the neighbouring nodes. VM ware offers an cloud environment that implement transferring data’s like as cloud.
