Abstract

Virtualization is a key concept in empowering the “Infrastructure as- a-Service (IaaS)” of cloud-based services. Live migration of virtual machines is the process of moving virtual machine from one physical host to another without interrupting other VMs. Migration of VMs supports the improved efficiency of resource usage and dynamic resource provision capabilities. The performance metrics of live migration are down time and total migration time. In this paper, a technique to reduce the total migration time of standard memory migration using the mirroring of VMs at destination host is proposed. It mainly concentrates on the total migration time and maximum profit of providers. The proposed technique avoids the iterative transmission of memory pages from the source host to destination host. Performance results depict that the proposed algorithm can reduce 36% of the data transmitted during migration and 26% of the total migration time when compared with pre-copy migration technique.

Summary

Introduction

Cloud computing (Josep et al, 2010) has been envisioned as the current generation architecture of IT enterprise. It provides infrastructure-as-a-Service (IaaS) (Bhardwaj et al, 2010) to the users as pay per usage basis. Virtualization technology is one of the key factors in the area of cloud computing. It separates the operating system from the underlying phyigsical machine using a hypervisor. Virtualization technology provides maximum profit to the cloud providers with less maintenance cost. It allows the creation and migration of virtual machines on a physical host
