Data IaC Skill

Infrastructure without code is infrastructure without memory. Manual console changes create drift that nobody notices until a deploy fails. Hardcoded values mean dev and prod diverge silently. Local state files mean one laptop death away from losing track of what's deployed.

IaC makes infrastructure reviewable, repeatable, and recoverable — the same code for every environment means what works in staging works in prod. These patterns aren't about tidiness. They're about being able to recover when things go wrong, which they always do.
