Abstract

Nowadays, due to the dynamic environment of service-based applications, the ability to adapt to environmental and contextual changes has become a crucial quality of such applications. However, providing these applications with adaptability capability at runtime so as to supports service-oriented development characteristics and to be able to run on a service integration infrastructure is a complex and difficult task. This paper presents a method to support realizing adaptability requirements in the development and evolution of service-based applications. To this end, the business process meta-model has been extended to monitoring and adaptation concerns. In addition, a set of mechanisms to transform these requirements to monitoring checkpoints and adaptation actions are presented in such a way that they can be deployed on enterprise service bus. The proposed method is evaluated on the basis of the several scenarios in a case study based on quantitative and qualitative experiments. The results of the evaluation demonstrate that the proposed method can effectively provide the possibility of developing adaptive behaviors.
