Infrastructure As Code Tutorial
This tutorial is intended to show what the Infrastructure as Code (IaC) is, why we need it, and how it can help you manage your infrastructure more efficiently.
It is practice-based, meaning I don't give much theory on what Infrastructure as Code is in the beginning of the tutorial, but instead let you feel it through the practice first. At the end of the tutorial, I summarize some of the key points about Infrastructure as Code based on what you learn through the labs.
This tutorial is not meant to give a complete guide on how to use a specific tool like Ansible or Terraform, instead it focuses on how these tools work in general and what problems they solve.
The tutorial was inspired by Kubernetes the Hard Way tutorial. I used it as an example to structure this one.
See my presentation at DevOpsDays Silicon Valley in which I talk more in depth about the tutorial.

Results of completing the tutorial
By the end of this tutorial, you'll make your own repository looking like this one.
NOTE: you can use this example repository in case you get stuck in some of the labs.
This tutorial assumes you have access to the Google Cloud Platform. While GCP is used for basic infrastructure requirements the lessons learned in this tutorial can be applied to other platforms.
