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.

Provisioning and configuration management

In Chapter 5, Connecting with Other Tools, you learned how to connect Terraform with various existing infrastructure tools. We've spent a lot of time on configuration management systems in particular. It is a popular thing to say these days that configuration management tools are not required any longer and immutable infrastructure, containers, or whatever is the best and only practice. Some people on the Internet even argue that you can replace Chef and Puppet only with Terraform. Certainly, that's not the case. Even though you could indeed replace Terraform with Chef or Puppet.

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 of whether you need to configure an EC2 instance, a big bare metal server, or networking hardware...
