IMPROVED MIGRATION STRATEGY USING ENERGY AWARE FAULT TOLERANCE CHECKPOINTING

Abstract

Server co-solidification and fault tolerance is one of the strategies to decrease the general resource utilization in the data centers other than different equipment and programming highlights. All such techniques provide energy efficient mechanism during allocation and reallocation of cloudlets to virtual machines. Virtualization techniques (VT) have made this possible with the assistance of different hypervisors responsible for creating virtual machines (VMs). Combining approaches for energy optimization along with fault tolerance, there are different parameters that should be tossed light into including execution, SLA (Service Level Agreement), CPU-I/O connection and so forth. Live migration of VM is the key to combining the servers without ceasing them in this manner with close to zero downtime for the frameworks. Unreasonable combination causes execution corruption which has extreme effect on the QoS (Quality of Service) of the application that are running in that condition. VM allotment and position are the principle issues in consolidation. Fault tolerance in proposed methodology is achieved through checkpoint with write through approach. The execution and energy consumption tradeoffs have been talked about in view of Greedy heuristics. At last the results are given a throw in terms of temperature, energy consumption, downtime and migration time.
