Creating a Topic and Subscription with Pub/Sub in Google Cloud
Pub/Sub is a fully-managed real-time messaging service that allows you to send and receive messages between independent applications. You can use Pub/Sub as messaging-oriented middleware or event ingestion and delivery for streaming analytics pipelines. In this hands-on Lab, we will set up a topic and subscription and then publish a message.
