Using software architecture principles and lightweight formalisation to build adaptive middleware

Abstract

The development of an adaptive middleware is still a challenge due to the complexity of dealing with traditional adaptation issues, such as Why to adapt? When to adapt? Where do we have to implement change? What kind of change is needed? How is the adaptation performed? This paper presents a solution that integrates software architecture concepts, lightweight formalisation and process mining to face the mentioned challenges. The solution reduces the effort to implement the middleware and reinforces safety properties at development time and when the middleware is already in execution. To evaluate the proposed solution, we carried out an initial experimental evaluation to measure the time to decide for an adaptation using process mining.
