Runtime Adaptation As a Programming Pattern in Service Composition

We propose a programming pattern for runtime architectural adaptation of service-oriented applications. Our approach enables transparent reconfiguration of distributed services at runtime leveraging on the key features for dynamic discovery binding of services supported developed in an existing platform. More precisely, in this paper we equip the platform with monitoring capabilities supporting the transparent reconfiguration of the architecture of service-oriented applications triggered by changes in the execution context. We demonstrate the effectiveness of the approach on the adaptable TeaStore benchmark.
