Abstract : Lately, the evolution of information technologies has been following two trends. On the one hand the proliferation of communicating devices contributes to the creation of an ambient intelligence. On the other hand, the booming of Internet associated with the rapid growth of data centres capabilities results in the emergence of an internet of services. In both domains, application design is challenged by the dynamic availability of computing resources and data. The combination of component-based software engineering and service-oriented computing techniques allows service bindings to be driven by policies. However, for the time being, policies either follow a dynamic approach which does not suit the needs of architectural stability when dealing with intermittent services, or a static approach which does not allow dynamic reconfiguration. The work presented in this thesis proposes a trade-off between the two approaches by considering service disruptions as a major concern. The proposed binding policy relies on service level agreements to be disruption-tolerant, since service-level agreements allow expressing and enforcing obligations regarding availability and quantified disruptions. This approach has been implemented on the OSGi service platform and iPOJO, a service-oriented component model for OSGi. iPOJO service dependency management has been extended in order to support our policy. The latter was validated both in the context of ambient intelligence, and on open-source and OSGi-based JOnAS application server.
