Abstract:
Cloud Computing brings an unparalleled shift to utility computing by providing unprecedented scalability and flexibility to IT services. Indeed, the concept of Cloud computing is linked intimately those of IaaS, PaaS, SaaS and collectively *aaS (Everything as a Service or Cloud services). This implies a service-oriented architecture where registries play an important role. Registries, which can be as many as the large number of Cloud services provider, compose the market where Cloud consumers and providers go to search and advertise Web services. With the proliferation of Cloud consumers and providers, finding an adequate Cloud service has become a complex task for a Cloud service consumer. In this paper we propose a functionality-driven clustering approach for Cloud service registries. This clustering will be helpful for selecting an adequate registry for service requesters. Since registries and communities are dynamic by nature, we also propose an approach for managing registries a
nd communities to reconcile conflicts resulting from the dynamic change aspect of service registries. Experimental evaluation shows that our approach is usable in realistic situations.
