Dynamic service reconfiguration and enactment using an open matching architecture

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.
