Connecting several thousand IoT (raspberry pi's) devices with a VPN

Hi all, I have a (currently theoretical) project involving putting thousands of RPi's in a bunch of remote locations to sense humidity, temperature and also take photos. I would like to secure them with a VPN but am curious as to whether this is a terrible idea or not.

If I was to launch an EC2 instance and host an OpenVPN server, would that be capable of supporting several thousand raspberry pi's? My goal is to have them on the VPN so I can SSH into them from any connected node

One thing I like about VPN is the *relatively* simple setup, on RPi it's just a sudo apt-away and it'll work.

What other issues come about with large quantity devices on VPNs?
