Is it better to have a single Direct Connect Gateway or multiple Direct Connect Gateways?

I'm trying to connect multiple VPCs (VPC-A, VPC-B) and multiple data centers (DC-A, DC-B) using Direct Connect Gateway (DCGW).

Which of the following configurations is better? Is it better to have a single Direct Connect Gateway or multiple Direct Connect Gateways?

  • VPC-A, VPC-B <-> DCGW <-> DC-A, DC-B
  • VPC-A, VPC-B <-> DCGW-A <-> DC-A
  • VPC-A, VPC-B <-> DCGW-B <-> DC-B

Short answer: It doesn't matter. If it were me, I'd go with a single Direct Connect Gateway.

More information is available in this blog post but it comes down to Direct Connect Gateway being highly redundant and acting as a BGP route reflector rather than being in the packet path.

2 is impossible. It is not possible to attach multiple Direct Connect Gateways to one VPC-VGW. Therefore, 1 is the answer to this question.
