Architecture Restructuring to Support Evolution towards Service-Oriented Architectures

The evolution of software systems and system landscapes towards service-oriented architectures is a widely discussed topic. Flexibility is a frequently named goal in this context. To reach this goal, complex information systems that are transfered to service-orientation have to be restructured. In practice the restructuring requires a high manual effort for understanding the existing system and the defintion of a mapping of its elements to a target architecture. Our model-based restructuring approach supports reengineers by semi-automating this task. In this paper we describe how this approach can be applied in the context of the evolution towards a serviceoriented architecture.
