摘要

Service based computing allows clients to dynamically bind services, and providers to modify the service implementation independently from their clients. The impossibility of statically determining which service implementation will be bound at runtime may lead to unexpected client-side failures. This position paper suggests a scenario in which service-based applications autonomously react to changes in the implementation of the used services, automatically detect possible integration mismatches, and dynamically execute suitable adaptation strategies. The proposed solution exploits ideas from autonomic computing and self-managed software. We propose a design methodology based on the definition of both test cases, to automatically diagnose service mismatches, and adaptation strategies, to overcome the revealed problems. We introduce a general runtime infrastructure that automatically embeds the test cases and the adaptation strategies into service based applications to guarantee self-adaptiveness.
