If you need to set up network connectivity for a large enterprise with many VPCs, how can Direct Connect Gateway and AWS Transit Gateway simplify your network configuration?
  • Direct Connect: private connection between AWS and customer network. Alternatively, you can set up a Site-to-Site VPN over the internet.
  • Direct Connect Gateway: if you have multiple VPCs in different regions, but in the same AWS account, then Direct Connect Gateway can help you access access all VPCs from the customer network.
  • AWS Transit Gateway: if you have multiple VPCs in multiple AWS accounts, you can connect everything to a Transit Gateway, which can facilitate connections between all VPCs and all customer networks connected via VPN or Direct Connect Gateway.
