To achieve this, I built out a cluster of hosts using Amazon's EC2 Container Service and run multiple standalone OpenVPN containers in an Auto-scaling group on each host, ensuring high availability. An Elastic Load Balancer routes traffic to the hosts, which then redirect traffic to the appropriate containers. I created a mounted volume on both of my ECS Nodes which utilizes Elastic Filesystem to store configuration files for my OpenVPN containers ensuring there is no duplication of data between the various containers. And....is it fast? You betcha! From the time ECS recognizes there has been a failure with one of the containers, a new one is up and running within 5 seconds.
