Terraform des del primer dia

Teams usually adopt Terraform after the console sprawl hurts — which means weeks of importing resources that already exist, each one a small archaeology project. Starting with Terraform on day one skips all of that. Every resource is born managed, reviewed and reproducible.

State belongs in a backend

Local state files are how two engineers overwrite each other's infrastructure. Remote state with locking — Azure Blob Storage or Google Cloud Storage — from the very first apply. This is a ten-minute setup that prevents the worst failure mode.

Modules later, flat first

Premature modules abstract over unknowns. Start with a flat configuration per environment, and extract modules only when the third copy of a pattern appears. Duplication across two environments is cheaper than the wrong abstraction.

Plan in the pipeline

Every pull request runs plan; only merges to main run apply — with approvals on production. The plan output is the review: readable proof of what will change before anything changes. Pair it with cost estimation so surprises arrive as comments, not invoices.
