From Design for Adaptation to Component-Based Resilient Computing

The evolution of systems during their operational lifetime is becoming ineluctable. Dependable systems, which continuously deliver trustworthy services, must evolve in order to comply with changes having different origins, e.g. new fault tolerance requirements, or changes in available resources. These evolutions must not violate their dependability properties, which leads to the notion of resilient computing. In this talk, I will present our methodology for developing adaptive fault tolerance mechanisms. We start with a « design for adaptation » approach, consisting of several design loops during which we refine a generic fault tolerance protocol execution scheme. This is followed by an experimental implementation of several fault tolerance mechanisms and the actual runtime transition between them, leveraging software engineering tools such as reflective component-based middleware which enable fine-grained manipulation of software architectures.

Keywords : resilience, adaptation, software architecture
