Abstract
A composite Web service provided as a “cloud” service should make its constituent Web services transparent to users. However, existing frameworks for composite Web services cannot realize such transparency because they lack capability of adapting changes of behaviors of constituents Web services and business rules of service providers. Service Supervision, proposed in the previous work, allows us to flexibly adapt a composite Web service by combining control execution functions which control behavior of running instances of composite Web services. However, much flexibility of the execution control functions sometimes makes it difficult to design adaptation processes due to absence of accumulated know-how such as guidelines. Moreover, it often costs a lot to port adaptation processes to the model of composite Web service to be adapted. To solve the problems, we first organized various adaptation processes based on some previous works. Then we proposed Service Supervision patterns, which consist of typical requirements for adaptation and WS- BPEL processes satisfying the requirements by using execution control functions. The patterns are easy for designers of composite Web services to understand and make it possible to reduce cost to port them to the model of a composite service.
