PO-JRA-2.3.1 Use Case Description and State-of-the-Art

The aim of this document is to introduce the most important aspects and the state-of-the-art of self-* infrastructures and service registry, binding and invocation. The property commonly referred as self-* is a collection of one or more reflexive properties expressing the ability of changing some aspects of the working behaviour of a computing entity. They are surveyed as self-optimisation and self-healing in a numerical simulation example; autonomic brokering; dynamic self-deployment of services; dynamic adaptation, self-optimisation, self-healing and self-configuration in a mobile environment. Software systems built on top of Service-Oriented Architectures (SOA) use a triangle of the three operations "publish", and "bind" in order to decouple the participants in the system. Key elements of the survey are Service Discovery (centralised vs. distributed, keyword-based, signature-based, semantics-based and context-based approaches), QoS-based service discovery, Dynamic Binding and Dynamic Invocation.
