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.
