Summary

In this chapter, you learned a lot about Infrastructure as Code principles and some tools that allow you to leverage them. There are many existing mature tools that take care of configuring what goes inside a single server, but there are not that many options when it comes to defining one level above a single server. We also listed the requirements for a tool that would take care of configuring this higher level. Then, we came to the conclusion that Terraform meets many, if not all, of these requirements. In the next chapter, we will finally get our hands dirty, install Terraform, and get to know how to use it to create a single AWS EC2 server.
