Building Adaptive Systems with Service Composition Frameworks

Abstract

Abstract. Frameworks that support the implementation and execution of service compositions are a fundamental component of middleware infrastructures that support the design of adaptive systems. This paper discusses the requirements imposed by adaptive middleware on service composition frameworks, and discusses how they have been addressed by previous work. As a result, it describes the design of a novel adaptationfriendly service composition framework that takes into consideration the requirements at three dierent levels: service programming model level, adaptation-friendly services level, and kernel mechanisms level.
