Abstract:
Availability and reliability of Web services are important issues for developing many electronic business applications. Unfortunately, it is hard to guarantee the availability of a service given that the number of its requests might be potentially huge. In this paper, we propose a novel approach for robust Web service provisioning based on mobile agent and resource discovery technologies. With our approach, new service instance can be instantiated at appropriate idle computing resources on demand, therefore reducing the risk of service being unavailable. We present a matchmaking algorithm for resources selection, as well as a multi-phase resource planning algorithm for composite Web services.
