By: Kirill Shirinkin

Overview of this book

Terraform is a tool used to efficiently build, configure, and improve production infrastructure. It can manage 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 complete management of infrastructure with Terraform, starting with the basics of using providers and resources. This book 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. It finishes with the complete workflow of managing a production infrastructure as code – this is achieved with the help of version control and continuous integration. At the end of this book, you will be familiar with advanced techniques such as multi-provider support and multiple remote modules.

Some people on the Internet can even argue that you can replace Chef and Puppet with only Terraform. Certainly, that's not the case. Even though you could replace Terraform with Chef or Puppet indeed.

Terraform covers only one level of infrastructure (as discussed in Chapter 1, Infrastructure Automation), and it does it reasonably well. For everything that goes inside a particular piece of hardware (or virtual hardware), you need a proper configuration management tool, regardless whether you need to configure EC2 instance, big bare metal server, or a networking hardware...
