Preface

Terraform is in huge demand in the IT market. There is a serious question about managing the IT infrastructure in code format. So, Terraform is an option for users that can help to build, configure, and manage the infrastructure.

This book provides you with a walkthrough from the very basics of Terraform to an industry expert level. It is a comprehensive guide that starts with an explanation of Infrastructure as Code (IaC), mainly covering what Terraform is and what the advantages of using Terraform are. Moving further, you will be able to set up Terraform locally in your system. In the next phase, you will get a thorough understanding of the different blocks, such as providers, resources, variables, output, and data, used in Terraform configuration code.

This book provides details of the Terraform backend, provisioners, loops, and inbuilt functions, and how to perform debugging with Terraform. In this book, you will learn how to integrate Terraform with Azure, AWS, and GCP. Along with integration, you will also be able to write Terraform configuration files covering all the three major clouds, which make up the best part of this book, so that you get a proper understanding of different use cases in all the major clouds, that is, Azure, AWS, and GCP. We also explain the complete Terraform life cycle, covering init, plan, apply, and destroy, which will help you to get an understanding of the Terraform workflow with CI/CD tools.

In the expert section of this book, we will discuss Terraform stacks and modules. In this section, you will understand how effectively you can write modules and combine those modules to build a complex stack covering all three clouds – Azure, AWS, and GCP. This helps users to manage huge enterprise-level infrastructure easily and effectively.

This book also covers Terraform products such as Terraform Enterprise and Terraform Cloud. You will get an understanding of the different features of Terraform Enterprise and Terraform Cloud. You will also get a great understanding of Sentinel, which is policy as code that can be implemented to ensure infrastructure is getting provisioned as per the necessary compliance before infrastructure actually gets provisioned into cloud providers such as Azure.

Overall, this book provides great learning for you about Terraform and using Terraform and how effectively you can use it to build and manage your enterprise-level infrastructure. Not only this, but with this book you can also get yourself prepared for the Terraform Associate exam and easily crack the exam.
