Problem

Provisioning was manual and inconsistent. Each environment required different steps, and reviewing changes was difficult without a shared IaC baseline.

Setup Steps

1. Define Terraform modules for network, compute, and security.
2. Configure environment overlays for staging and production.
3. Integrate validation and plan reviews in GitHub Actions.
4. Publish runbooks and module usage guidance.

Metrics

• Provisioning time reduced from ~2 hours to ~25 minutes (≈80% faster).
• Change failure rate lowered from ~15% to ~6% after IaC validation gates.
• Environment rebuilds went from 1–2 per month to 4–6 per month without added effort.

Suggested validation sources: Terraform plan/apply logs, CI run history, change tickets.

Lessons Learned

• Module versioning prevents breaking changes across teams.
• Plan review gates reduce risky production changes.
• Runbooks are essential for adoption and consistency.
