Runtime Evolution of the Adaptation Logic in Self-Adaptive Systems

Self-adaptive systems, which are highly related to Autonomic Computing, are a response to the increasing complexity and size of information systems. They are able to adapt their behavior to changes in the environment or system resources. A self-adaptive system consists of managed resources that realize functionality and an adaptation logic that controls the adaptations. So far, many research has been performed on adapting the managed resources. However, only few works cover adapting the adaptation logic, which might be necessary in several cases, e.g., when the architecture of the managed resources changes. This work adresses why adaptation of the adaptation logic might be beneficial, how it can be achieved, and what challenges arise.
