What Is Sub Messaging

Publish/subscribe messaging, or pub/sub messaging, is a form of asynchronous service-to-service communication used in serverless and microservices architectures. In a pub/sub model, any message published to a topic is immediately received by all of the subscribers to the topic.

What is Pubsub used for?

Pub/Sub, which stands for Publisher/Subscriber, allows services to communicate asynchronously, with latencies on the order of 100 milliseconds. Pub/Sub is used for streaming analytics and data integration pipelines to ingest and distribute data.

Is Pub sub a message queue?

Like message queuing, publish-subscribe (commonly referred to as “pub-sub”) messaging moves information from producers to consumers. However, in contrast to message queuing, publish-subscribe messaging allows multiple consumers to receive each message in a topic.
