This chapter introduces a service.engineering.platform (CLMS) that caters for all the phases of the service engineering life cycle. Although complete coverage of the service life cycle is important, currently, few software environments and platforms manage it, with the majority of such environments dealing with just service execution (delivery). It is nevertheless important to have a single environment/platform that handles the whole service life cycle with seamless transition between phases (CBDI Forum, 2005). To deal with these requirements, the CLMS platform adopts a model-driven approach (see Chapter VI). More specifically, the platform seamlessly links business service specification models to realizable services and manages the delivery of the latter in an environment that monitors services execution. Moreover, this approach ensures that alternative service deployment techniques (e.g., proactive as well as reactive service delivery systems) and service execution environments can be accommodated. This is of particular importance today, with service engineering still evolving and with new service paradigms and competing technologies appearing all the time.
