Abstract:
Working groups have proposed building a layered set of protocols to solve Cloud Computing interoperability challenges. This is not the problem of application portability which calls for standardized programmer interfaces. This is the problem of generalized, transparent, back-end cloud-to-cloud federation. Current Intercloud designs do not envision each cloud provider establishing connectivity with another cloud provider in a Point-to-Point manner, as this will result into the n2 complexity problem. Instead, Intercloud Directories, Exchanges, and Gateways will help facilitate as mediators for enabling connectivity and collaboration among disparate cloud providers in a manner analogous to the Internet itself. These Intercloud elements would implement a profile of protocols becoming known as Intercloud protocols. Researchers and working groups have proposed a layered set of such protocols using Extensible Messaging and Presence Protocol for transport, and Semantic Web with Resource Description Framework for resource matching. This paper builds on that work and discusses the next layer up, where a specific use case of federation is explored. We find that the back-end implementation of cloud-distributed, unstructured storage can be extended to generalized cloud-to-cloud federation using a Simple Storage Replication Protocol (SSRP), which is built on top of the base Intercloud protocol set. This paper details SSRP.
