Production Grade IaC setup
summary
Production-grade IaC pipeline built around Terraform managing 120–130 VMs with ~30 volumes, multiple VPCs and five product scopes across dev/prod/test environments. Uses Atlantis plan/comment in PRs and CI that enforces pre-commit checks, fixed Terraform/provider versions and automated applies. Onboards legacy resources with terraform import, warns about single-state corruption and recommends splitting projects by provider/region, owning modules per team, and running post-apply scripts (Ansible Tower/playbooks) to finish provisioning.
