Abstract:
In order to reduce the power consumption and server physical resources astage in IaaS,a resource wastage model is established.By incorporating energy consumption model of servers,a virtual machine placement strategy is proposed for optimizing the consumption of resource and energy.Moreover,this paper designs and implements a multi-objective virtual machine placement algorithm to achieve the energy efficiency and optimization of physical resource.Finally,it is shown from simulation results that the proposed algorithm not only effectively reduces the energy consumption of server cluster but also improves the utilization ratio of server physical resource simultaneously.
