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.
