Question

A retail company has two Direct Connect locations, one in London and one in Frankfurt, each terminating a dedicated connection with a transit VIF attached to a separate Transit Gateway in eu-west-2 and eu-central-1. The company also has on-premises data centers connected at each Direct Connect location. The networking team wants traffic between the two on-premises data centers to flow directly across the AWS global backbone between the two Direct Connect locations, without traversing the customer's own WAN and without routing through a Transit Gateway. Which approach meets this requirement?

Accepted Answer

Enable SiteLink on the transit VIFs at both Direct Connect locations so the data centers can exchange routes over the AWS global network.

Answer

Create an inter-region Transit Gateway peering between the two Transit Gateways and advertise the on-premises prefixes across the peering.

Answer

Attach both transit VIFs to a single Direct Connect gateway and rely on the Direct Connect gateway to route between the two connections.

Answer

Provision a Site-to-Site VPN between the two customer gateways over public VIFs to bridge the two data centers.
