An Analysis about the Security of the Current Open Source Cloud Platform

Cloud computing is convenience, flexibility, costeffective, making it the rapid development. Cloud computing business have been developed by many famous IT companies such as Microsoft, Google, Amazon, and we call it Cloud Service Provider (CSP). Many small companies also want to deploy their services on the cloud for reducing their costs. However, one issue that can't be ignored is that security needs to be analyzed before the cloud platform deployment. The current consensus is that security of cloud is the biggest obstacle to its development. Current cloud security issues are mainly concentrated in the theoretical stage, manifested in what cloud platform should have to ensure security; each cloud platform has its own implementation, and does not disclose its security implementation mechanisms. Therefore, for companies who want to deploy their own private cloud platform, open source cloud platform is a good choice. This paper focus on the mainstream open source cloud platform (OpenStack, CloudStack, Eucalyptus), and make an analysis of the security to the user as a reference when they choosing the open source cloud platform.
