A Survey on Virtual Machine Migration Techniques in Cloud Computing Infrastructure

Cloud computing has been considered as a new fashion of providing Information Technology services such as computational and storage resources to individual users and organizations. To achieve this purpose, it uses internet in order to give service to users. In fact, cloud is a new technology of distributed computing which is based on virtualization technology. With respect to benefits of virtualization, today, most of data centers use this technology for improvement of task efficiency and increase of their own clients. This technology transforms a physical server to several virtual machines (VMs), and the VMs shares a logical file format. With regard to this property, we can transfer the VMs from one place to another place that is called migration. The computational environments that use this technology are data centers which their load scales dynamically. Migration is used to satisfy the goals such as load balancing, fault tolerance, power management, reducing response time, increasing quality of service, and repairing and maintaining servers. In this paper, new methods of VMs migration techniques are studied and compared from efficiency point of view.
