Towards Measuring the Adaptability of an AO4BPEL Process
This work addresses the challenge of assessing adaptability in extended-BPEL frameworks for service-oriented computing, but it is incremental as it builds on existing frameworks without introducing a new paradigm.
The authors tackled the problem of evaluating adaptability in service-oriented computing by proposing metrics to measure the adaptability of AO4BPEL processes, which enables dynamic adaptation to changes in business requirements.
Adaptability is a significant property which enables software systems to continuously provide the required functionality and achieve optimal performance. The recognised importance of adaptability makes its evaluation an essential task. However, the various adaptability dimensions and implementation mechanisms make adaptive strategies difficult to evaluate. In service oriented computing, several frameworks that extend the WS-BPEL, the de facto standard in composing distributed business applications, focus on enabling the adaptability of processes. We aim to evaluate the adaptability of processes specified from the extended-BPEL frameworks. In this paper, we propose metrics to measure the adaptability of an AO4BPEL process. The metrics is grounded in the perspective that a process is capable of dynamically adapting to changes in business requirements. This opens potential future work on evaluating the adaptability of processes specified from various aspect-oriented WS-BPEL frameworks.
