A Survey on Auto Live Migration Mechanism in Cloud Environment

Abstract

Cloud Computing has recently emerged as a compelling paradigm for delivering computing services to users as utilities in a pay-as-you-go manner over the internet. Virtualization is a key concept in cloud computing. Virtualization technology refers to the creation of a virtual machine that acts like a real hardware with an operating system. Live migration is the task of moving a virtual machine from one physical hardware environment to another without disconnecting the client. Its facilities for efficient utilization of resources (CPU, memory, Storage) to manage load imbalance problem and also useful for reduction in energy consumption and fault management. For live migration of the virtual machine cloud provider needs to monitor the resources of all hosts continuously. So there are techniques for automation of this live migration when required. This method is called auto live migration techniques. This paper presents a detailed survey on Auto Live Migration of Virtual machines (VM) in cloud computing.
