Overview of this book

HashiCorp Configuration Language (HCL) has changed how we define and provision a data center infrastructure with the launch of Terraform—one of the most popular and powerful products for building Infrastructure as Code. This practical guide will show you how to leverage HashiCorp's Terraform tool to manage a complex infrastructure with ease. Starting with recipes for setting up the environment, this book will gradually guide you in configuring, provisioning, collaborating, and building a multi-environment architecture. Unlike other books, you’ll also be able to explore recipes with real-world examples to provision your Azure infrastructure with Terraform. Once you’ve covered topics such as Azure Template, Azure CLI, Terraform configuration, and Terragrunt, you’ll delve into manual and automated testing with Terraform configurations. The next set of chapters will show you how to manage a balanced and efficient infrastructure and create reusable infrastructure with Terraform modules. Finally, you’ll explore the latest DevOps trends such as continuous integration and continuous delivery (CI/CD) and zero-downtime deployments. By the end of this book, you’ll have developed the skills you need to get the most value out of Terraform and manage your infrastructure effectively.

When we create resources in a cloud architecture, we often tend to forget that this incurs a financial cost that depends on the types of resources that are created. This is even more true with automation and IaC, which allow us to create a multitude of resources using a few commands.

One of the interesting features of the version of Terraform Cloud that's integrated into the paid plan is cost estimation, which makes it possible to visualize the cost of the resources that are handled in the Terraform configuration while it's being run.

In this recipe, we will learn how to use cost estimation in Terraform Cloud.
