Overview of this book

Terraform is a tool used to efficiently build, configure, and improve the production infrastructure. It can manage the existing infrastructure as well as create custom in-house solutions. This book shows you when and how to implement infrastructure as a code practices with Terraform. It covers everything necessary to set up the complete management of infrastructure with Terraform, starting with the basics of using providers and resources. It is a comprehensive guide that begins with very small infrastructure templates and takes you all the way to managing complex systems, all using concrete examples that evolve over the course of the book. The book ends with the complete workflow of managing a production infrastructure as code—this is achieved with the help of version control and continuous integration. The readers will also learn how to combine multiple providers in a single template and manage different code bases with many complex modules. It focuses on how to set up continuous integration for the infrastructure code. The readers will be able to use Terraform to build, change, and combine infrastructure safely and efficiently.

Chapter 2. Deploying First Server

Now that we know which problem Terraform solves, we can proceed to learning how exactly it works and how to use it. In this chapter, we will learn a bit about Terraform's history, install it on our workstation, prepare our working environment, and run the tool for the first time. After getting everything ready for our work, we will figure out what a Terraform provider is, and then we will take a quick tour of what AWS and EC2 are.

With this knowledge in place, we will first create an EC2 instance by hand (just to understand the pain that Terraform will eliminate), and then we will do exactly the same with the help of the Terraform template. That will allow us to study the nature of the Terraform state file. Once we know that, we will update our server using the same template, and finally, destroy it. By the end of the chapter, you will already have solid knowledge of the Terraform basics, and you will be ready to create a template for your existing infrastructure...
