ESBs (Enterprise Service Buses) allow applications to communicate with one another, where these do not already include services or interfaces designed for that purpose.
ESBs are often presented as new architectures that use different techniques like transformation, information transfers and routing, and web services.
ESBs act as “mediators” between clients and service providers (applications).
Benchmark solutions in the open source universe include the likes of Talend ESB, Mule and Petals.
