According to abstract we are working on multiple cloud system for storing more data in the cloud or sharing of huge information from one place to another place with minimum cost. According to that we are trying to this project reduce same data to did not store in the cloud that why we are using multiple cloud application or websites to store more data because every cloud is providing minimum space in the cloud & over data is time to time increases. So that we are using MapReduce technology to get same to store different-different data or marge the as a same file of data or Map scale back also identify for checked is their same data or what because we are using of multiple cloud storage to take more space. if data is similar so we are trying to use & identify which gateway server or LBA (Logical Block area) are store as same data of files. This method mainly from uses of multiple big organization, government, Telecom Industry and much more. A hash capability created use of session middle of the topology among minimizes the task all the same is not movement valued in this topology. Why we are working on network topology because multiple customer is working or uses of internet in the same time to reduce the network error or control the network traffic without taking extra time or reduce the network traffic values.
