Research of Dynamic Scheduling of Resources Based on Virtual Machine Migration in Cloud Environment

Abstract

Now Cloud data centers exist problems of load imbalance and high energy consumption. The paper studied the resource dynamic scheduling strategy in cloud environment based on the virtual machine live migration and proposed an effective virtual machine target node selection strategy. The algorithm chose the best migration node by calculating the resource demand of the virtual machine for the node to measure the matching degree between the virtual machine and the nodes. Finally, we implemented the scheduling strategy on the cloud simulation platform CloudSim. The experiments results show that the strategy proposed by the paper can improve the load balance of the cluster, reduce the energy consumption of the data center to a certain extent compared with other scheduling algorithms.
