The Apache Software Foundation is now incubating a web services broker/ Enterprise Service Bus (ESB) project called Synapse. The new effort aims to provide an open source implementation that will challenge existing commercial implementations that are based on proprietary protocols.
According to the Synapse proposal submitted to the Apache Software Foundation,"Synapse will be a robust, lightweight implementation of a highly scalable and distributed service broker / ESB based on Web services specifications."
The effort is being backed by Blue Titan, Infravio, Sonic Software, Iona and WSO2.
