Intercloud Message Exchange Middleware
Cloud Interoperability has been a core issue pertaining Intercloud and Cloud Federation. Several vendor-based proprietary solutions and open-source middleware are present for the resolution; however, these solutions are highly coupled to particular cloud environments. For heterogeneous clouds to exist in an interoperable environment, the need of a vendor-independent, secure and reliable message exchange middleware is critical. In this paper, considering general cloud architecture, the authors are presenting a Publish-Subscribe based middleware for Intercloud Message Exchange. Intercloud Message Exchange is an implementation of Data Distribution Service (DDS).
