Why this is the answer
Pub/Sub uses a publisher-subscriber model to decouple systems that produce events from systems that consume them.

This design lets producers and consumers operate independently without direct one-to-one connections. The value is reliable asynchronous message delivery across applications and Google Cloud services.
