Infrastructure as Code
Terraform makes infrastructure reviewable, repeatable, and easier to reason about. The main benefit is not typing fewer clicks; it is turning infrastructure changes into versioned decisions.
Module Boundaries
Good modules hide noisy details without hiding important ownership. Keep modules focused around stable concepts such as networking, compute, data stores, or service deployment.
State Management
Remote state should be protected and shared deliberately. Locking, backups, and access control matter because Terraform state often contains sensitive operational truth.
CI/CD
Run format and validation checks on every pull request. Generate plans in CI, but keep production apply steps gated by human review unless the environment is intentionally disposable.
