Terraform at Scale
Infrastructure as Code for Teams That Outgrew a Single State File
By Yuki Tanabe
Multi-cloudPractitionerPlatform Engineering
Terraform is pleasant for one team and one environment. The difficulty begins when twelve teams share a provider account, modules develop versioning politics, and a single apply can take forty minutes.
Yuki Tanabe treats Terraform as an organizational problem as much as a technical one: how to split state so blast radius matches ownership, how to version modules without freezing everyone, how to detect and reconcile drift continuously, and how to make plan output something a reviewer can actually read.
Applies to both AWS and GCP providers, with the differences called out where they matter.
What you'll learn
- Split state so that blast radius matches team ownership
- Version and release modules without blocking consumers
- Detect and reconcile drift as a continuous process
- Make plan diffs reviewable by humans under time pressure
