Resource Overview​

A Transit Gateway is a network transit hub that can be used to interconnect Virtual Private Clouds (VPCs) and on-premises networks. As cloud infrastructure scales globally, inter-region peering connects Transit Gateways using the AWS global infrastructure. Data is automatically encrypted and never transmitted over the public internet.
