AWS Direct Connect with private VIF over virtual private gateway - AWS Prescriptive Guidance

AWS 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 AWS 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 AWS Direct Connect gateway, which is a global construct, you can use existing AWS 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 AWS Direct Connect gateway. Alternatively, you can use Transit Gateway to attach to thousands of VPCs. For more information, see the next section.
