Abstract

The cloud computing paradigm promises increased flexibility and scalability. However, in private cloud environments this flexibility and scalability is constrained by the limited capacity. On the other hand, organizations are reluctant to migrate to public clouds because they lose control over their applications and data. The concept of a hybrid cloud tries to combine the benefits of private and public clouds, while also decreasing vendor lock-in. This paper presents PaaSHopper, a middleware platform for hybrid cloud applications that enables organizations to keep fine-grained control over the execution of their applications. Driven by policies, the middleware dynamically decides which requests and tasks are executed in a particular part of the hybrid cloud. We validated this work by means of a prototype on top of a hybrid cloud consisting of a local JBoss AS cluster, Google App Engine, and Red Hat OpenShift.
