A Novel Approach to Improve the SLA and Energy Consumption of Grid Networks

In recent years, the IT infrastructure due to the demand for computing power which used by applications are rapidly growing and modern data centers in grid computing are hosting a variety of advanced applications. One of the most important objectives of the VM placement algorithm is determine the optimal location of virtual machines in physical servers So that the minimum number of physical servers to be turned on for enhancing the overall performance of the grid environment. Efficient placement of VMs in PMs (Physical Machines) in grid environment improves resources utilization and energy consumption. In this paper, we employ TOPSIS method to design a integrated VM placement algorithm, called TOPSIS VM Placement (TVMP) which can reduce the number of running PMs and lower the energy consumption. Extensive simulation results in GridSim environment show that the proposed algorithm outperforms existing algorithms in terms of migration, traffic cost, SLA and energy
