Performance evaluation of a massively parallel ESB-oriented architecture

Enterprise Service Bus (ESB) is an SOA-based software architecture for business application integration in distributed and heterogeneous environments. Most of open-source or commercial solutions offer the same set of basic services such as message transformation, message routing, security, etc. however, none of them take advantage of the multicore/multiprocessor technologies which make possible the massively parallel processing. This work concerns performance evaluation of a massively parallel ESB oriented architecture (denoted MPAB). After a brief description of its main components, we present the results of this evaluation based on operational analysis.
