Infrastructure as Code: Terraform Habits That Stick

Click-ops fades the day the person who “just knew” leaves. OnesDev treats Terraform (or equivalent IaC) as product code: reviewed, planned, and applied through the same discipline as app releases — see boring releases.

Remote state is non-negotiable

Store state remotely with locking. Never commit state files. Separate state per environment (or use clear workspaces with discipline) so a staging experiment cannot trash production. Pair state with least privilege — IAM least privilege without the pain.

Modules that match how you think

• Group by product capability (network, data, compute), not by raw resource type alone
• Pin provider and module versions; upgrade deliberately
• Keep root modules thin; push reuse into shared modules
• Document required variables and outputs like an API

Environments and landing zones

IaC shines when accounts and networks are intentional. Use the same modules across staging and production with different variables — and ground multi-account layout in an AWS landing zone for product teams. Wire applies into your CI/CD checklist.
