Enterprise service bus (ESB) is currently the most promising approach for business application integration in distributed and heterogeneous environments. It allows to deploy a service-oriented architecture (SOA) by the integration of all the isolated applications on a decentralized platform.Several commercial or open source ESB-based solutions have been proposed. However, to the best of our knowledge, none of these solutions has integrated the parallel processing. The integration of parallelism in the treatment allows to take advantage of the multicore/multiprocessor technologies and thus can improve greatly the ESB performance. However, this integration is difficult to achieve, and poses problems at multiple levels (communication, synchronization, etc). In this study, we present a new massively parallel ESB architecture that meets this challenge.
