Transit Gateway


Resource Icon​

Resource Overview​

The Transit Gateway is a network transit hub that can be used to interconnect Virtual Private Clouds (VPCs) and on-premises networks. As cloud infrastructure expands globally, inter-region peering uses AWS global infrastructure to link Transit Gateways together. Data is automatically encrypted and does not traverse the public internet.
