Architecture orientée services et adaptation. Un état des lieux motivant l'approche CompAA

This paper presents a state of the art of service oriented architectures and speciall how services adaptability is managed in this kind of open environments. Then, a summary notices the relevance of a component / agent mixed approach and the use of P2P (Peer-to-Peer) technologies. Taking into account this analysis, we introduce the main lines of the CompAAapproach. Finally, an experimentation in the area of collaborative learning on the Grid validates our approach.
