The old version used EBS storage to store MongoDB's data. That solution isn't very good. If AZ with EBS volume will be unavailable we lose our VPN server for some amount of time.
In the new version, I use EFS (Elastic File System) to store MongoDB's data. It helps us to avoid a situation when one AZ is down and we can't connect to the VPN server.
