  1. Chapter 23:Service Management Service-Oriented Computing: Semantics, Processes, Agents– Munindar P. Singh and Michael N. Huhns, Wiley, 2005

  2. Highlights of this Chapter • Enterprise Resource Planning • WS Management Framework • WS Distributed Management • Scalability • Robust Services Service-Oriented Computing: Semantics, Processes, Agents - Munindar Singh and Michael Huhns

  3. Advanced Composition: 1 • Suppose an application needs simply to sort some data items, and suppose there are 5 Web sites that offer sorting services described by their input data types, output date type, time complexity, space complexity, and quality: • One is faster • One handles more data types • One is often busy • One returns a stream of results,another a batch • One costs less Sort1 Application ? Sort2 ? ? ? Sort3 Sort5 Sort4 Service-Oriented Computing: Semantics, Processes, Agents - Munindar Singh and Michael Huhns

  4. Advanced Composition: 2 • Possible approaches • Application invokes services randomly until one succeeds • Application ranks services and invokes them in order until one succeeds • Application invokes all services and reconciles the results • Person organizes all services into one service using BPEL4WS • Application contracts with one service after requesting bids • Services self-organize into a team of sorting services and route requests to the best one • The last two require that the services behave like agents • The last two are scalable and robust Service-Oriented Computing: Semantics, Processes, Agents - Munindar Singh and Michael Huhns
