I have recently had the cloud version of VPMS installed and it is great as long at something called the VPN is working. I have used Amazon web services.  I have no idea what the VPN is - is if part of Amazon? (AWS). I assume I will have to get an IT person to explain this but if there is someone to explain how all this fits together I will be grateful. 

The problem is that if the VPN drops out I cant use VPMS. Where is the VPN, who fixes it and how can I reconnect if it drops out?
