Daily Term: Publish/Subscribe

Publish/Subscribe

Publish/Subscribe (Pub/Sub) is a messaging pattern where publishers send messages to a topic, and subscribers receive messages from topics they’re interested in, without direct coupling. For example, in a Pub/Sub system like Google Cloud Pub/Sub, a weather service might publish updates to a 'weather' topic, and multiple apps subscribe to receive them. Pub/Sub enables scalable, event-driven systems but requires managing subscriptions and message filtering.
