Virtual Machine Migration Policies in Clouds

Amritpal Singh, Supriya Kinger

Abstract: The virtual machine (VM) migration brings multiple benefits such as higher performance, improved manageability and fault tolerance. Failures are often common in systems comprising thousands of processors and often we encounter these failures using a well defined Fault Tolerance Mechanism (FTM). This technique is enabled using a Virtual Machine (VM) migration policy. Managing the placement and migration of VMs in a data centre is a significant challenge. This paper presents an overview of Cloud and its Services, then Fault Tolerance is discussed in detail, giving review of VM Migration policies
