Chapter 9: Understanding Terraform Stacks

In the previous chapter, we started our journey by understanding the Terraform configuration file, and we explored how Terraform language files, which are human-readable, differ from JSON files, which are machine-readable. Moving further, we saw the different data types supported by both JSON and Terraform files. We also discussed industry best practices for writing Terraform configuration files with major cloud providers, such as Google Cloud Platform (GCP), Azure, and Amazon Web Services (AWS).

In this chapter, we will discuss how we can handle a large enterprise infrastructure deployment, upgrading, and so on using Terraform configuration code. We will be discussing infrastructure deployment to GCP, Azure, and AWS using a Terraform stack. In this chapter, you will gain a thorough understanding of Terraform stacks and modules and how stacks can be used effectively for infrastructure deployment and updates.
