An Efficient Live Virtual Machine Migration Technique in Cloud Computing Environment

Abstract

Due to the growing number of computer nodes deployed in cloud enterprise, automatic management of electronic applications is certain. To provide various services, there will be rises in procurement, maintenance, and electricity prices. Virtualization technology is getting common in cloud computing environment, which enables the efficient use of computing resources to decreases the operating cost. Virtualization technology allows to share the same physical resources among different users and helps to reach optimum utilization of the physical resources. Hardware virtualization is the process of partitioning the physical machines into the logical machine using virtualization software called hypervisor and each logical machine is called virtual machine. Migration of a virtual machine is simply transferring the virtual machine running on a source machine to the target machine. Live virtual machine migration is migrating a running virtual machine on the source node to the destination node without interrupting any lively network connections, even after the virtual machine is copied to the target node. It is considered live because the original virtual machine is running, while the migration is in progress. An Enormous benefit of doing the live migration is the very small downtime in the order of milliseconds and small total migration time. Live migration has been expansively used in load balancing, energy reduction and dynamic resizing to increase availability and hardware maintenance. In this paper, we designed and implemented a new enhanced and efficient live virtual machine migration algorithm that reduces the total time migration and the total pages transferred and eliminates service downtime.
