Google Cloud Pub/Sub

Google Cloud Pub/Sub is a messaging service that allows applications to communicate asynchronously. It works like a mailing system: publishers send messages to topics, and subscribers receive messages from those topics. This setup enables real-time data transfer, decoupling parts of a system so they can operate independently and efficiently. It's scalable, reliable, and ideal for handling large volumes of data or events, such as notifications, logs, or updates, ensuring information is delivered promptly and processed as needed across distributed systems.
