The cloud storage systems are becoming more popular and all the organizations are moving towards the direction of cloud for storing the data. Moving all the data in one cloud causes problems like vendor lock-in, increased service costs, and data availability. In this paper, we are introducing the DCStore, a cloud-of-clouds storage services designed for an organization to outsource their data into the clouds. In order to overcome the above mentioned problems we combine three key techniques. First, DCStore will remove all the redundant data at the client-side to save storage using via application-aware chunking method. Second, in order to achieve high availability of data DCStore uses an inner-chunk based erasure coding scheme which distributes unique chunks across multiple clouds. Finally, a Container-based share management strategy is used for optimizing the performance. Load Balancing enables enterprise to manage workload demands or application demands by distributing resources among numerous computers, networks or server. Therefore, our experimental evaluations can improve performance, storage space and can achieve high availability of data.
