Infrastructure as Code, Free

Stop clicking around cloud consoles — define your servers, networks, and services as version-controlled code. Learn the two disciplines: provisioning with Terraform and configuring with Ansible. All resources free and current.

Infrastructure as Code (IaC) means your entire environment — VMs, networks, load balancers, databases — is described in files you commit to git, so it's repeatable, reviewable, and disaster-recoverable. Terraform (and its ecosystem) provisions the infrastructure; Ansible configures what runs on it. Together they're among the most valuable DevOps skills you can learn.
