Model-based Recovery Connectors for Self-adaptation and Self-healing

Self-healing and self-configuration are highly desirable properties in software systems so that components can dynamically adapt to changing environments and recover from failure with minimal human intervention. This paper discusses a model-based approach for self-healing and self-configuration using recovery connectors. A recovery connector extends connectors in component-based software architectures and serviceoriented architectures with self-healing and self-configuration capabilities so that a component or service can be dynamically adapted and recovered from failures. The design of the recovery connector is based on the MAPE-K loop model and can handle both recovery and adaptation.
