Pub/Sub
Publish-Subscribe Pattern
Definition
Pub/Sub decouples message producers (publishers) from consumers (subscribers) through a message broker. Publishers send messages to named topics; subscribers receive all messages on topics they subscribe to, without knowing about publishers.
This enables fan-out (one message to many consumers), temporal decoupling (consumers don't need to be online when messages are published), and service independence.
