In this chapter, we'll go beyond the essentials of using Terraform we covered in Chapter 2, Provisioning IaaS with Terraform. We'll discover many important techniques to use Terraform in conjunction with other players in the field such as Docker and Chef, how it can be used in multiple environments (such as development/staging/production), how powerful it can be to manage not only infrastructure but many SaaS as well, and how to integrate the tool within a team workflow (sharing, synchronizing, maintaining, harmonizing, and so on). These topics are all equally important, as they will define the quality of our daily work and our ability to interact with other people, services, and systems.
