Pub/Sub

A messaging pattern where publishers send messages to topics without knowledge of subscribers, and subscribers receive messages from topics they're interested in, enabling asynchronous and decoupled communication between services. Modern distributed architectures rely on it to coordinate workloads across multiple nodes and regions.

Pub/Sub is profiled on the APIs.io network. Tagged areas include Architecture, Asynchronous, Distributed Systems, Messaging, and Pub Sub.
