-- You can create one or more AWS Direct Connect private virtual interfaces linking to a virtual private gateway. A virtual private gateway can be managed via Amazon Virtual Private Cloud (VPC) console or the <http://docs.aws.amazon.com/AWSEC2/latest/APIReference/ApiReference-query-CreateVpnGateway.html EC2 CreateVpnGateway> action.
