The Performance Evaluation of Virtual Machine Placement Algorithm Based on WebCloudSim

摘要

Effective virtual machine placement algorithms can improve network resource utilization in cloud data centers. In order to design a more effective VM placement algorithm, we usually rely on a large-scale experimental platform to evaluate and verify its performance. However, large-scale experiment may have a huge impact on data center network, which makes it very unlikely to happen. Therefore, researchers need an experiment platform that can support large-scale environment to meet the above requirements. In order to evaluate the performance of virtual machine deployment algorithm, this paper first designs and implements a cloud data center network experiment system, WebCloudSim, which can support the joint experimental verification of real environment and simulation environment. Then, based on WebCloudSim, the paper implements three classic algorithms for virtual machine deployment, and verifies and analyzes the results. The experimental results show that WebCloudSim can effectively support the performance evaluation of virtual machine placement algorithm.
