Performance Evaluation of the CloudStack Private Cloud

Abstract

The number of open source cloud platforms is increasing day-by-day. The features of these platforms vary significantly and this creates a difficulty for the cloud consumers to choose the platform based on their requirements. In this paper we build a private cloud using Cloudstack, a popular open source platform used to build Infrastructure as a service (IaaS) cloud. We present its architecture and analyze performance of virtual machines initiated and managed by the CloudStack in terms of CPU usage, memory bandwidth, disk I/O speed and networking performance using suitable benchmarks. Different virtual machine management operations such as add, delete and live migration are also evaluated. The performance evaluation of CloudStack can help to determine its suability to be adopted as on premise cloud solution.
