Terraform Module Library

This one gives you production-ready Terraform module patterns for AWS, Azure, and GCP. It's built around a consistent module structure with main.tf, variables.tf, outputs.tf, and proper testing setup using Terratest. You get concrete examples like a full AWS VPC module with validation blocks, subnet management, and tagging patterns, plus guidance on module composition when you need to chain resources together. The best practices section is solid on the basics: semantic versioning, input validation, and documentation. Use this when you're building reusable infrastructure components or trying to standardize how your team provisions cloud resources. It won't tell you which architecture to choose, but it will show you how to package it cleanly once you've decided.
