What is Google Cloud Pub/Sub architecture?

Google Cloud Pub/Sub is a messaging service that allows you to send and receive messages between independent applications. It uses a publish-subscribe model, where publishers send messages to a topic, and subscribers receive messages from that topic.

How does the publish-subscribe model work?

In the publish-subscribe model, publishers send messages to a topic without knowing who the subscribers are. Subscribers express interest in specific topics and receive messages published to those topics, allowing for decoupled communication.

What are the benefits of using Pub/Sub?

Some benefits include scalability, reliability, and real-time messaging. It allows for asynchronous communication and can handle large volumes of messages.

Can you explain how to set it up?

To set up Google Cloud Pub/Sub, you need to create a Google Cloud project, enable the Pub/Sub API, create a topic, and then create subscriptions for that topic. You can use the Google Cloud Console or the command line.
