Mountain View, CA – May 2, 2011 WSO2, the lean enterprise middleware provider, today announced that it has been cited by Forrester Research as a leader in “The Forrester Wave™: Enterprise Service Bus, Q2 2011” report1, published April 25, 2011. The report’s findings were based on a 109-criteria evaluation of both commercial and open source ESB vendors. Significantly, WSO2 scored 4.47 out of a possible 5.00 points for “current offering,” which was based on Forrester’s evaluation of the 100% open source WSO2 Enterprise Service Bus (WSO2 ESB) 3.0.

According to the Forrester ESB Wave report2, “The broad capabilities ESB products providehave made them a popular choice for meeting general integration needs and supporting efforts to implement a service-oriented architecture.”The report further notes that, “The increasing capability of both commercial and open source ESBs and their lower price points compared with comprehensive integration solutions (CISes) will continue to drive high interest in these products from organizations that are modernizing their application development infrastructure.”

“We designed our WSO2 ESB with the idea that a lean, adaptive architecture could provide the high performance and flexibility that enterprises need, and today we have customer implementations where WSO2 ESBs are reliably running 800 million-plus messages per day,” said Paul Fremantle, WSO2 co-founder and CTO and vice president of the Apache Software Foundation Synapse Project. “We are excited to be identified by Forrester as a leader in its latest ESB Wave report. It further validates our commitment to reinventing middleware around the next generation of open source standards to meet enterprises’ real world demands.”
