What it means
The hierarchy controls policy inheritance, billing, identity scope, delegated administration, quotas, isolation, and the blast radius of mistakes or compromise.
Why it matters
A deliberate hierarchy makes ownership and policy understandable. An improvised hierarchy produces permission sprawl, weak cost attribution, and inconsistent controls.
Practical focus
- Design the hierarchy around ownership and control boundaries
- Separate production, development, security, and shared services appropriately
- Apply policy at the highest safe level
- Maintain an inventory of owners and lifecycle status
Common mistakes
- Using one account or subscription for everything
- Mirroring a temporary organization chart too literally
- Moving resources without reviewing inherited policy
