Cloud Native Development with Google Cloud

Chapter 5. Project 1: Tag Updater with Cloud Functions

In this initial project, you will write the first part of the Skills Mapper application. You will be introduced to some of the higher-level abstractions in Google Cloud and be shown how you can solve a real-world problem at a minimal cost.

You will learn how to solve the requirement in three ways:

Note

The code for this chapter is in the tag-updater folder of the GitHub repository.
