GCP’s hierarchy is the foundation of multi-project security.
Levels
- Organisation — top; tied to your Google Workspace / Cloud Identity domain
- Folders — group projects (by environment, business unit)
- Projects — workload boundary; resources live here
- Resources — buckets, instances, etc.
IAM inheritance
Roles granted at higher levels apply to all child resources. Org-level Owner = Owner everywhere. Use folder-level for tighter scoping.
Org Policy Service
Set guardrails enforced organisation-wide. Examples:
compute.disableSerialPortAccessiam.disableServiceAccountKeyCreationstorage.publicAccessPreventioncompute.skipDefaultNetworkCreation
Constraints inherit; can be overridden at project level only with explicit org-admin permission.
