An Adaptive Fault Reduction Scheme to Provide Reliable Cloud Computing Environment

The Now a days Cloud technologies has become an essential trend in the market of information technology. Virtualization and Internet-based Cloud computing leads to different kinds of failures to arise and hence, leads to the requirement for reliability and availability has become an essential issue. To make ensure for reliability and availability of cloud technologies, a scheme for fault tolerance need to be developed and implemented. As the majority of the early schemes for fault tolerance were focused on the utilization of only one way to tolerate faults. This paper presents an adaptive scheme that deals with the difficulty of fault tolerance in various cloud computing environments. The projected scheme employs adaptive behavior during the selection of replication and fine-grained checkpointing methods for attaining a reliable cloud platform that can handle different client requests. In addition to this the algorithm also determines the best suited fault tolerance method to every designated virtual machine. As the proposed scheme adapts fault tolerance methods it improves the performance of the cloud in terms of availability, throughput, cloud overheads due to huge number of check points and maintenance cost.
