Abstract: Service-oriented architectures (SOAs) provide loose coupling and software reuse in enterprise applications. SOAs enable applications to heal themselves by failing over to alternate services when a critical application component or service reference fails. The numerous intricate details of identifying errors and planning a recovery strategy make it hard to develop applications that can heal by swapping services. Model-driven engineering (MDE) offers a potential solution to handling the complexity of building applications that can heal by swapping services. This paper presents an MDE technique called Refresh that is based on microrebooting and uses 1 feature models to derive a new and correct service composition when a failure occurs 2 an application's component container to shutdown the reference to the failed service 3 the application container to reboot the subsystem. We also present the results from a case study that shows Refresh significantly reduces both modelling and healing implementation effort.

During the past two decades he has led pioneering research on patterns, optimisation techniques and empirical analyses of object-oriented and component-based frameworks and model-driven development tools that facilitate the development of middleware and applications for distributed real-time and embedded (DRE) systems. He is an expert on DRE computing patterns and middleware frameworks and has published over 400 technical papers and nine books that cover a range of topics including high-performance communication software systems, parallel processing for high-speed networking protocols, quality-of-service (QoS)-enabled distributed object computing, object-oriented patterns for concurrent and distributed systems model-driven development tools.
