Terraform plans as teaching moments

Terraform plan output reviewed before cloud pipeline deploy

Infrastructure modules can feel opaque when learners only run apply. In week three of Cloud Ingestion, mentors require annotated plan screenshots before any deploy.

Students highlight IAM changes, new buckets, and Lambda triggers. A common catch: public ACL assumptions on legacy buckets. We fix in plan, not in production.

The capstone adds cost tags and a monthly estimate sheet. Reviewers ask for a rollback story—what destroys cleanly if the ingest path is wrong.

This mirrors how platform teams in KR enterprises gate changes, without pretending every org uses identical tooling.
