Description

Google Cloud Pub/Sub is a scalable, durable event ingestion and message delivery system that allows you to create an infrastructure whose responsibility is to handle message queues. Pub/Sub delivers low-latency, durable messaging by using two core components: topics and subscriptions. You can create a topic where messages will be sent to, and subscriptions attached to the topics. All messages sent to a specific topic will be delivered to all the subscriptions attached. All the components that get messages from a subscription are called subscribers. For more detailed info about what is Cloud Pub/Sub, you can refer to the official GCP guide.

In this lab, you will understand the core components of a Pub/Sub system, you will create a topic and attach a subscription to it, you will send a message to the topic, and you will create a batch job using Cloud Dataflow to import messages to your topic from a text file stored in a Cloud Storage bucket.

Learning Objectives 

Upon completion of this lab you will be able to:

  • Understand what topics and subscriptions are in Pub/Sub
  • Define a topic
  • Create a subscription and attach it to a topic
  • Run a Cloud Dataflow job to import messages from a Cloud Storage bucket.

Intended Audience

This lab is intended for:

  • Google Cloud Associate Cloud Engineer (ACE) certification candidates
  • Solutions architects who want to define and deploy a message delivery system
  • Individuals who want to understand how a message delivery system works

Prerequisites

This lab has no prerequisites.
