An Adaptive Enterprise Service Bus Infrastructure for Service Based Systems

Service-based systems (SBS) increasingly need adaptation capabilities to agilely respond to unexpected changes (e.g. regarding quality of service). The Enterprise Service Bus (ESB), a recognized infrastructure to support the development of SBS, provides native mediation capabilities (e.g. message transformation) which can be used to perform adaptation actions. However, the configuration of these capabilities cannot usually be performed at runtime. To deal with this limitation, Adaptive ESB Infrastructures have been proposed which leverage their mediation capabilities to deal with adaptation requirements in SBSs in an automatic and dynamic way at runtime. This paper presents a JBossESB-based implementation of an Adaptive ESB Infrastructure and demonstrates its operation by describing their main functionalities. The paper also presents an evaluation of the implemented solution.
