Description

This paper focuses 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. Data can easily be recovered from another node in case of one nodes unavailability. Workload division is a method for distributing workloads across all the available nodes by using replication. Data security has consistently been a major issue in information technology. In the cloud computing environment, it becomes particularly serious because the data is located in different places even in all the globe. Data security and privacy protection are the two main factors of user’s concerns about the cloud technology. In this project the system propose a Division and Replication of Data in the Cloud for Optimal Performance and Security (DROPS). The system use the aforesaid architectures because they constitute the modern cloud infrastructures. It focuses on the security of data within the cloud computing domain that is not considered. It fragments the file and makes use of the cloud for replication.
