Dynamic Management of Virtual machines for Server Consilidation in Data Centers

Abstract

Cloud computing technology whichprovides computing resource on demand over the internet as aservice. To meet this requirement virtualized data centers areestablished all around the world. However, data centers utilizelarge amount of electrical power. Thus results in high operatingcosts and emits carbon dioxide to environment. Carbon dioxideemitted from cloud data centers cause global warming.This paper provides a model and techniques for thedynamic management virtual machines in data centers. The mainpurpose is to increase the utilization of computing resources andminimize energy consumption by switching off the idle nodes.Live migration technique, moving virtual machines betweendifferent physical servers, is mainly used to reduce the number ofactive compute nodes in cloud data centers with minimaldowntime. In this paper, we provide an architecture and softwareframework of open stack neat, for dynamic virtual machineconsolidation in open stack cloud deployment. Open stack is anopen source cloud platform which provides infrastructure as aservice solution. Open stack allows users to deploy virtualmachines which manages different workloads.
