Self Improvement of Cloud Operation Using Dynarep Algorithm and Skewness Algorithm

Abstract — A system that uses virtualization technology to allocate data centre resources dynamically based on application demands and support green computing by optimizing the number of servers are already in use. For quantifying the unevenness in the utilization of multiple resources on a server, known as skewness, the server makes the average utilization of resources. Fault tolerance is also a major concern to guarantee availability and reliability of critical services as well as application execution. To formalize the resource allocation problem as that of dynamically maximizing the cloud utility under CPU and memory constraints, an algorithm called Dynarep is proposed to automatically determine optimal fault tolerance strategy for these significant components
