Traditional hierarchical Service Level Management (SLM) frameworks fail to cope with the challenges imposed by the runtime dynamics of Service Oriented Architectures (SOA). This paper introduces a decentralised management approach that successfully uses emerging self-management techniques to realise a flexible SLM system and presents an architecture that implements this approach. The architecture consists of a modular self-manager framework that provides the basis for component-level and workflow-level management. It provides sensor and effector modules to monitor and manage different classes of applications. Integration with existing SOA components is based on the Service Component Architecture (SCA). The presented framework has been prototypically implemented and is currently evaluated in terms of efficiency and scalability.
