Usage-aware service identification for architecture migration of object-oriented systems to SoA

Abstract

Organisations currently migrate the architecture of their traditional systems to service-oriented systems. Since their systems usually serve a lot of clients, a diversity of the system usage may exist. The evolution of a service-oriented system is facilitated if the offered services are specific for each group of clients. However, the state-of-the-art service-identification approaches do not consider the system usage. Thus, we propose an online process that dynamically re-identifies services by the arrival of new method traces of the system usage. The preliminary evaluation of our process on real-world case-studies shows high effectiveness on identifying usage-aware services.
