DRF4SOA: A Dynamic Reconfigurable Framework for Designing Autonomic Application Based on SOA

Service Oriented Architecture (SOA) allows modeling dynamic interaction between heterogeneous providers. Coupling with Service Component Architecture (SCA) enables governing the development of complex applications. The dynamic reconfiguration of such applications is a key feature, since it gives measures to ensure runtime adaptation in order to guarantee Quality of Service (QoS) and manage the performance. For instance, recovering a QoS degradation requires the identification of its sources and the capacity of reconfiguration planning and execution. This paper presents DRF4SOA, a Dynamic Reconfigurable Framework to design autonomic application based on SOA, that implements the autonomic control loop phases (Monitoring, Analysis, Planning, Execution) with SCA in order to provide flexibility to support evolving of itself and to include new non-functional requirements at runtime.
