Preface

With ever-rising adoption of Cloud technologies and infrastructure SaaS products, as well as always the constantly sizes of infrastructures the need, to manage it all in the form of code becomes more and more apparent. Cloud providers such as Amazon Web Services have dozens of services and all of them require secure, re-usable and predictable configuration. Terraform, the primary tool for this job, appeared in 2014 and quickly gained popularity among system administrators and software developers. Since the first release, Terraform has achieved a lot of traction. It became the new de facto tool for managing the cloud environments. Terraform is also a tool that is quite new, that is changing with every release and that requires a new mindset and new practices from teams that adopt it.

In this book you will learn how Terraform works and how to use it, with many examples of real-life applications of it. You will explore modern approaches to managing the infrastructure, such as Infrastructure as Code and Immutable Infrastructure. You will also learn many new small utilities that either improve the experience of working with Terraform or cover the layers that Terraform is not supposed to manage. By the end of this book not only will you now how to use Terraform, but you will be in an expert in treating your whole Infrastructure as Code, with Terraform being the core of this procedure.
