Approaches are provided for message broadcasting within a clustered computing environment such as a Cloud computing environment. Specifically, a message received from a message queue (e.g., on a message queue server) is processed at a single node of a plurality of nodes within the clustered computing environment. This single node identifies a set of message listeners to whom the message should be broadcast (e.g., based on a topic of the message and an association of the topic to the set of message listeners). The single node then publishes the message to the set of message listeners. Delivery confirmations, responses, etc., associated with the message are then tracked, processed, and/or routed by the single node.
