You've learned Terraform! No, seriously, you did. You might (we hope) still be busy with doing a final big exercise from the end of the previous chapter. That's alright--it's not the simple one and it takes time.
We finished covering everything that is there to learn about this fancy new (relatively new) HashiCorp tool. In this chapter, you won't see much code samples, diagrams, and logs. Instead, we are going to recap what you've learned, talk about some pros and cons of introducing Terraform to your organization, and speculate about the future of this utility. Don't skip this chapter, especially the recap sections! It will have a lot of useful tips, as well as references to books and articles that will help you to dive deeper into each particular topic, related to the Terraform usage. These were not included in chapters themselves in order to focus on learning Terraform and not to spread attention on dozens of other things.
