Abstract

Service-oriented systems increasingly need to be self-adaptive in order to respond to dynamic business requirements and to satisfy quality of service conditions in a highly distributed context. Achieving such self-adaptive behavior requires a comprehensive approach throughout the different service-oriented architecture (SOA) layers to avoid, for example, conflicting adaptation actions. In turn, Enterprise Service Buses (ESBs) provide several out-of-the-box mediation features (e.g. message transformation, routing, monitoring) that enable adaptation at the infrastructure layer. However, dynamic adaptation (i.e. adaptation at runtime), a fundamental requirement in self-adaptive systems, is still an open issue in ESB-based platforms. This paper presents an approach that leverages ESBs mediation features to provide dynamic adaptation capabilities within an ESB-based service infrastructure layer. This work, which is based on concepts and frameworks defined within the S-Cube project, intends to be a step forward in developing a comprehensive approach to support self-adaptive service-oriented systems.
