How to build scale & maintain 45 pub Terraform mod. with over 100 million provisions
summary
Collection of 45 public modules that have run in production for over 100 million provisions, with concrete choices: support freezes on Terraform 0.13, reject provisioners/overrides, and split into resource vs composition modules to keep scope small. Automation uses pre-commit hooks plus tf-lint and terraform validate to catch ~90% of issues; there are thousands of issues/PRs showing why strict naming, documentation, sane defaults, and composability matter. Testing focuses on static checks, localstack for fast integration, and generated IAM policies rather than heavy end-to-end test suites.
