Abstract	The Service Oriented Architecture (SOA) model fosters dynamic interactions of heteregeneous and loosely- coupled service providers and consumers. Specifications like the Service Component Architecture (SCA) have been used to tackle the complexity of developing such dynamic applications; however, concerns like runtime management and adaptation are often left as platform specific matters. At the same time, runtime QoS requirements stated in Service Level Agreements (SLA) may also evolve at runtime, and not only the appli- cation needs to adapt to them, but also the monitoring and management tasks. This work presents a component based framework that provides flexible monitoring and management tasks and allows to introduce adaptivity to component-based SOA applications. The framework implements each phase of the autonomic control loop as a separate component, and allows multiple implementations on each phase, giving enough run- time flexibility to support evolving non functional requirements on the application. We present an illustrative scenario that is dynamically augmented with components to tackle non- functional concerns and support adaptation as it is needed. We use an SCA compliant platform that allows distribution and architectural reconfiguration of components
