Autonomic computing seeks to render computing systems as self-managed. In other words, its objective is to enable computer systems to manage themselves so as to minimise the need for human input [5,6]. Software architectures can be used in order to express constraints to be maintained all along the execution of a system and, conversely, to present the state of the running system. In this paper, we present an approach where design and runtime architectures are used to manage service-oriented systems. We show how concepts of design time and runtime can be linked and exploited by an autonomic manager or by a human administrator. This approach is validated on a real use case belonging to the pervasive health domain and built with the Orange Labs.
