A Study on Service Performance Evaluation of Openstack

Virtual network is an important part of the cloud computing, Its management is achieved by the Quantum component of Open stack, which is one of the most popular cloud management platform. Currently, Quantum component has two deployment plans that is the single-host plan and the multi-host plan. Others' lab previously about the comparison of two deployment plans is incomplete and unsatisfactory. In this paper, we introduce the single-host and the multi-host deployment plan after analyzing the work mechanism of the Quantum component. Then, we deploy Hadoop on the Open stack to compare the network performance of single-host plan and the multi-host plan through the service performance of Hadoop. Experiment results show that virtual network performance of the multi-host plan has been greatly improved to compare the single-host plan.
