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.

Preface

Immutable infrastructure


Terraform works best if you adapt Immutable Infrastructure principles. It can also work pretty well if you use containers. Read Rebuilding our infrastructure (https://segment.com/blog/rebuilding-our-infrastructure/) from Segment about how they used Terraform with AWS Elastic Container Service and Docker for the new version of their infrastructure. It has good examples in the Continuous Integration part as well.

The ECS plus Terraform approach seems to gain higher adoption in general; for example, check out a presentation about more or less the same idea by Yevgeniy Brikman, named Infrastructure as Code: Running microservices on AWS with Docker, Terraform, and ECS (http://www.ybrikman.com/writing/2016/03/31/infrastructure-as-code-microservices-aws-docker-terraform-ecs/).

Finally, there is a really good blog post by Simone Gotti about rolling upgrades with Terraform. Simone also published all the code to perform such upgrades, so you can easily use it. He published on...
