Direct Connect with private VIF over virtual private gateway

The following diagram shows how you can connect VPCs and on-premises environments through a virtual private gateway over a private VIF by using Direct Connect.

Connecting VPCs and on-premises through virtual private gateway over private VIF

Most large enterprise customers deploy resources within a large number of VPCs across multiple AWS Regions and require connectivity from data centers that are spread across geographies. By using an Direct Connect gateway, which is a global construct, you can use existing Direct Connect connections to connect to resources in VPCs across AWS Regions. You can associate up to 20 virtual private gateways (each attached to a VPC) in different AWS Regions, directly to an Direct Connect gateway. Alternatively, you can use Transit Gateway to attach to thousands of VPCs. For more information, see the next section.
