Cross-Account Architecture
The architecture used to provide Direct Connect service to Cornell AWS accounts utilizes AWS Transit Gateways (one per AWS region) in a central AWS account (cu-cit-network) to which VPCs in Cornell AWS accounts are attached. Multiple VPCs in a single AWS account can be attached to Direct Connect in this way.
Each VPC connected to this architecture has full connectivity to all other VPCs connected to the architecture, without need for VPC-to-VPC peering.
