Cross-Account Networking & AWS Organizations Settings

Multi-Account Analogy: Think of each AWS Account as a separate branch office building, and AWS Organizations as the corporate parent company. VPC Peering is a direct 1-to-1 skybridge between two buildings. Transit Gateway (shared via AWS RAM) is a central Grand Central Station hub that connects all company buildings while keeping Dev employees out of the Production building. Cross-Account PrivateLink is a secure drive-thru window that exposes just one service to another account (even if both buildings numbered their rooms identically!).
