Production-Grade Terraform Patterns

Welcome to the Production-Grade Terraform Patterns series.

In this 6-part guide, I walk through the journey of maturing your infrastructure from simple scripts to a robust, self-updating platform.

What you will learn:

#

• Part 1: How to structure repositories using the Split-Repo Pattern to isolate failure domains.
• Part 2: How to write “Production-Ready” modules that are strictly versioned, validated, and tested.
• Part 3: How to automate the entire release lifecycle (Changelogs, Tags) using Release Please.
• Part 4: Why you should favor secure Git Tags over Private Registries for internal code.
• Part 5: How to automate dependency upgrades across 100+ environments using Renovate.
• Part 6: How to scale execution securely using TACOS (Atlantis, Digger).
