AWS Managed VPN

Amazon VPC provides the option of creating an IPsec VPN to connect your remote networks with your Amazon VPCs over the internet. You can take advantage of multiple VPN connections to route traffic, from your router, between your Amazon VPCs over the internet or AWS Direct Connect, as shown in the following figures.

AWS Direct Gateway VPC-to-VPC Routing

This approach is suboptimal from a routing perspective since the traffic must traverse to router on your network, but it gives you a lot of flexibility for controlling and managing routing on your local and remote networks, and the potential ability to reuse VPN connections.
