This paper focuses on the potential security risk embedded in the model of multi-tenant sharing virtual machine service. Also the characteristics of current Java virtual machine standard model and the typical problems that may be encountered under the multi-tenant circumstances will be further discussed. Additionally, major solutions to the above problems of Java application server, including MVM, I-JVM and improved OSGI model, will be deeply analyzed in this paper. Through introduction to the GAE of commercial multi-tenant PaaS platform, this paper presents a clear and precise discussion and clarification to the solutions of security problems on the platform of multi-tenant PaaS.
