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.

This was the longest and perhaps most important chapter so far! All these new infrastructure tools are useless if we don't know how to use them in production.

Now we know how to scale our Terraform resources with count and how to work around a lack of conditional statements in the HashiCorp Configuration Language with the help of the count property. You learned how to reference resources grouped with count, how to target them, and how to provision them properly. We also discovered a few more useful functions of Terraform.

Most importantly, you learned what immutable infrastructure is and what benefits it brings along to modern operations. With the theory in hand, we taught ourselves how to use yet another HashiCorp tool, Packer, and created a few AMIs with it. And, as we know that Terraform is perfect for immutable infrastructure, we took a deep look at multiple ways to do upgrades of complete instances. We did so manually, with self-written scripts, and we also used Auto Scaling groups...
