Publish/Subscribe in IBM App Connect Enterprise Version 11.0

In IBM App Connect Enterprise Version 11.0, publish/subscribe functions are provided by the MQTT and Publication (WebSphere MQ) message flow nodes. IBM App Connect Enterprise uses publish/subscribe to notify applications of significant events that occur in integration nodes. IBM App Connect Enterprise provides a built-in MQTT broker to support these integration node events. The MQTT broker is enabled by default for all events, apart from monitoring events. If you have installed WebSphere® MQ, you can also use the WebSphere MQ pub/sub broker in place of, or alongside, the built-in MQTT broker. If you have a queue manager that is specified on the integration node, the MQ pub/sub broker is enabled by default for all types of event, including monitoring events. You can choose which type of pub/sub broker to use based on your processing requirements and your existing architecture.
