In the previous Terraform labs, I created Google Cloud resources directly from the root configuration. That worked, but the structure was still quite simple. Every resource was defined directly inside the main Terraform configuration. For a small lab, that is fine. But as the infrastructure grows, putting everything in one root configuration can become harder to maintain. So in this lab, I started learning Terraform modules. The goal is to turn the previous VPC and subnet configuration into a reusable local module. But instead of only creating one VPC and one subnet, I made the lab slightly more practical by creating: one custom VPC network two subnets two firewall rules reusable module inputs module outputs remote state using Google Cloud Storage What is a Terraform Module? A Terraform module is a collection of Terraform configuration files that are managed together. In simple terms, a module is like a reusable infrastructure component.…
