Dynamic Service Reconfiguration and Enactment Using an Open Matching Architecture

Abstract

Abstract:An architecture for dynamic reconfiguration of complex services, in which the enactment is automated, and the matching of services is not limited to a pre-determined set of matchers and repositories, is presented. The proposed architecture consists of three, previously developed, components: the CoWS template-based reconfiguration service, the Knoogle MatchMaker service, and the Triana workflow enactment engine. This architecture has the following innovative aspects: 1) automated adaptation of complex services, which is more flexible than existing approaches based on replacing failing instances of services within a workflow, 2) use of heterogeneous components that may be both local and distributed, and 3) dynamic selection of matchers and repositories.
