IBM Integration Bus (former IBM WebSphere Message Broker) transforms messages and converts transport protocols formats between requestor and service. The WebSphere Message Broker runtime reduces cost and complexity of IT systems by unifying the method a company uses to implement interfaces between disparate systems.
IBM Integration Bus provides capabilities to build solutions needed to support diverse integration requirements through a set of connectors to a range of data sources, including packaged applications, files, mobile devices, messaging systems, and databases. The key feature of the WMB product is the ability to abstract the business logic away from transport or protocol specifics.
