Connect your VPC to other VPCs and networks using a transit gateway

You can connect your virtual private clouds (VPC) and on-premises networks using a transit gateway, which acts as a central hub, routing traffic between VPCs, VPN connections, and Amazon Direct Connect connections. For more information, see Amazon Transit Gateway.

The following table describes some common use case for transit gateways and provides links to more information in the Amazon VPC Transit Gateways.

Example Usage
Centralized router Configure your transit gateway as a centralized router that connects all of your VPCs, Amazon Direct Connect, and Amazon Site-to-Site VPN connections. For more information, see Example: Centralized router.
Isolated VPCs Configure your transit gateway as multiple isolated routers. This is similar to using multiple transit gateways, but provides more flexibility in cases where the routes and attachments might change. For more information, see Example: Isolated VPCs.
Isolated VPCs with shared services Configure your transit gateway as multiple isolated routers that use a shared service. This is similar to using multiple transit gateways, but provides more flexibility in cases where the routes and attachments might change. For more information, see Example: Isolated VPCs with shared services.
