Explanation: AWS Direct Connect locations in the United States can access public resources in any US region. You can use a single AWS Direct Connect connection to build multi-region services. To connect to a VPC in a remote region, you can use a virtual private network (VPN) connection over your public virtual interface.
To access public resources in a remote region, you must set up a public virtual interface and establish a border gateway protocol (BGP) session. Then your router learns the routes of the other AWS regions in the US. You can then also establish a VPN connection to your VPC in the remote region. Any data transfer out of a remote region is billed at the remote region data transfer rate.
