In this paper, the authors focused on the problem of availability of data on the data nodes and replication process. Cloud computing service providers require a system which can handle a large number of requests at a time. For processing the huge cloud of requests for data access, services need to be highly available. System keeps multiple copies of the blocks of data on different nodes by replication. Load on system may increase when there is high demand of a data is present and one or more sites providing that data fails.
