Adaptation space exploration for service-oriented applications

This article proposes an automatic optimization process for adaptation space exploration of service-oriented applications based on trade-offs between functional and extra-functional requirements. The proposed method combines the use of metaheuristic search techniques and functional/extra-functional patterns (i.e., architectural design patterns and tactics). Besides, the proposed methodology relies on the standard Service Component Architecture (SCA) for heterogeneous service assembly and its runtime platforms. As a proof-of-concept, this article provides also an example of instantiation of the process together with an experimentation on a sample application and a numerical evaluation of the scalability of the approach.
