How to reduce the bandwidth cost on OpenVpn server?

[monalisa]

I have a general question. I made a VPN accessible in mobile platforms, it’s hosted on AWS and everything works fine. The only problem is it costs a lot of money, (Amazon bill is over $1000) and not because of CPU or memory usage, which are negligible, but because of bandwidth usage.

For our Devops friends- It’s not that I need an orchestrator like Kubernetes, because it works the same way if there are 300 people connected or only 1, everything works fine on a single instance (only the bills changes)

Is there any way to reduce the cost? Did I make the VPN in the correct way? How can I reduce the bandwidth per user?

I used this script https://github.com/angristan/openvpn-in ... install.sh in order to install it, on Ubuntu 18.04 machines and the clients are mobile applications.
Thanks you for your help!

You need to look at a WAN Optimization solution.
