Publish / Subscribe (using Channels/Topics)
Publish/Subscribe is an asynchronous messaging model where the sender (publisher) of a message and the consumer (subscriber) of a message are decoupled. When using the channels/topics, readers and writers of events are both connected to a common topic or channel. The publisher publishes data to the channel. The channel exists within the Universal Messaging realm server. As messages arrive on a channel, the server automatically sends them on to all consumers subscribed to the channel. Universal Messaging supports multiple publishers and subscribers on a single channel.
