Terraform Best Practices

A comprehensive IaC guidebook from Terramate covering 37 rules across everything from state management and security to module design and testing. It's organized by priority, so you can focus on the critical stuff first (remote backends, credential handling, workspace isolation) before worrying about performance tuning. Each rule includes wrong and right code examples, which is helpful when you're reviewing PRs or setting up team standards. The taxonomy is solid, using prefixes like `security-`, `module-`, and `state-` to keep things organized. Best used when establishing conventions for a team or when you need to justify why something should be done a certain way. It's opinionated but pragmatic, which is exactly what you want from a style guide.
