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.

Storing state files remotely

As you know, by default, Terraform will store the state file on your local disk and you have to figure out yourself how to distribute it within your team. One option you learned is to store it in the git repository: you get the workflow, you get the versioning and you even get some level of security on top. But there is also a concept of remote state provided by Terraform.

The idea is that, before you start applying your templates, you configure a remote storage. After that, your state file will be pulled and pushed from a remote facility. There are 11 backends for your state provided by Terraform: Consul, S3, etcd, Atlas, and others. You will learn how to use Simple Storage Service (S3) for this purpose.


Atlas is a commercial offering from HashiCorp. One part of it is named Terraform Enterprise: it combines secure remote state storage, versioning of state file changes, logs of Terraform runs, and some other features. It is well integrated with GitHub. You...
