Abstract
In this work, we present novel techniques for flexible and reliable execution and deployment of Web services which can be integrated into existing service platforms. The first technique, dynamic service selection, provides a layer of abstraction for service invocation offering Web services the possibility of selecting and invoking Web services at runtime based on a technical specification of the desired service. The selection can be influenced by using different types of constraints. The second technique, a generic dispatcher service capable of automatic service replication, augments Web services with load balancing and high availability features, without having to consider these features at the services’ development. We implemented these techniques within the ServiceGlobe system, an open Web service platform.
This research is done in cooperation with the Advanced Infrastructure Program (AIP) group of SAP.
