Terraform Infrastructure

This is a solid reference for working with Terraform across AWS, Azure, GCP, and other providers. It covers the full workflow from HCL syntax and variable types to state management, modules, and enterprise patterns. The examples are practical, showing validation rules, locals, built-in functions, and real resource configurations. Use it when you're provisioning infrastructure as code, building reusable modules for your team, or managing multi-environment deployments. The function reference alone saves you from constantly checking docs. It assumes you understand why you'd want declarative infrastructure but doesn't assume you've memorized Terraform's type system or expression syntax.
