Enterprise AWS Governance (2026): OU Taxonomy, Policy Layering, and Exception RFCs That Scale

Control Tower gets you an org; it does not tell you how many OUs you need or which policy type owns VPC public access. Since re:Invent 2024 you have four layers — SCP, RCP, declarative, and tag policies — and RCP coverage grew through Feb 2026 (DynamoDB). A composite 60-account enterprise cut exception SCP attachments from 14 ad-hoc to 3 time-boxed RFCs in two quarters by moving accounts out of "temporary" prod OUs.

Cross-Account Patterns Beyond the Landing Zone (2026): RAM, Delegated Admin, Route 53 Profiles, RCPs, and Declarative Policies

Your landing zone set up the org, OUs, and baseline SCPs — then most teams stall, duplicating resources per account and wiring brittle cross-account role chains. Since re:Invent 2024 the toolkit changed: RCPs bound what can be done TO a resource (even by external principals), declarative policies enforce EC2/VPC/EBS config state that survives new APIs, and one Route 53 Profile can push DNS to up to 5,000 VPCs. Here is the mechanism-by-job decision matrix and a rollout order that avoids lockouts.
