Terraform at Scale: An Operating Model Problem, Not an HCL Problem
Most Terraform horror stories get blamed on the language. The real culprit is usually upstream of any HCL: unclear ownership, state boundaries drawn in the wrong places, review paths that don't match who actually understands the blast radius, and promotion models that let changes leak between environments. Fix the syntax and you still have the mess; fix the operating model and the syntax problems mostly evaporate.
This talk reframes “Terraform at scale” as an organizational design question. It walks through where the seams should fall — module ownership, state segmentation, who reviews what, how changes get promoted — and why teams that get those right ship infrastructure changes calmly while teams that don't fight their own tooling forever.
What you’ll take away
- Why most Terraform pain is an ownership, state-boundary, and review-path problem before it is an HCL problem.
- How to draw state boundaries and module ownership that match real blast radius.
- What a promotion model that prevents environment drift actually looks like.
- How to tell an operating-model problem apart from a genuine tooling problem.
Who it’s for
Platform engineers, DevOps leads, and architects responsible for infrastructure-as-code across more than one team. Fits platform and IaC conference tracks (IaCConf-style audiences) and internal platform reviews.
