The integration of third-party web services helps solve complex business problems and reduce risks, costs and time-to-market. However, the task of the integrators is challenged by services that are maintained by different organizations, and may evolve dynamically and autonomously. The impossibility of statically determining which service implementation will be bound at runtime may lead to unexpected failures. This paper presents a novel approach for designing self-adaptive serviceoriented applications, which autonomously react to changes in the implementation of the services, automatically detect possible integration mismatches, and dynamically execute suitable adaptation strategies. The solution proposed in this paper, is based on a runtime infrastructure that automatically tests remote web services, uses test results to diagnose service mismatches, and executes adaptation strategies to overcome the revealed problems without user intervention.

Abstract

The integration of third-party web services helps solve complex business problems and reduce risks, costs and time-to-market. However, the task of the integrators is challenged by services that are maintained by different organizations, and may evolve dynamically and autonomously. The impossibility of statically determining which service implementation will be bound at runtime may lead to unexpected failures. This paper presents a novel approach for designing self-adaptive serviceoriented applications, which autonomously react to changes in the implementation of the services, automatically detect possible integration mismatches, and dynamically execute suitable adaptation strategies. The solution proposed in this paper, is based on a runtime infrastructure that automatically tests remote web services, uses test results to diagnose service mismatches, and executes adaptation strategies to overcome the revealed problems without user intervention.
