Organization Policies at Scale: Attach High, Pick Managed Constraints, Roll Out in Dry Run

Tue, 10 Nov 2026 09:00:00 -0500

This post is for cloud engineers building a GCP foundation with Terraform who want Organization Policy to keep working once the hierarchy grows past a few projects. My argument is that org policy at scale comes down to three decisions. Attach constraints as high in the hierarchy as you can. Handle exceptions with conditions, not scattered overrides. Once other teams own workloads, never enforce a new constraint until it has run in dry-run mode. By the end you should know where each policy belongs, which kind of constraint to reach for, and how to promote one from observed to enforced.

Make every GCP VPC network custom mode from the first apply

If you are a cloud engineer building a Google Cloud foundation in Terraform, the network is one of the first modules you write and one of the last you will want to change. My argument is that every VPC network in your foundation should be custom mode from the first apply, and new projects should not get a default network at all. This post covers why, which settings carry the decision, and where auto mode is still fine.
