I am running an application on an EC2 in a public subnet. I've now been required to move this application into a private subnet but people still want to have access to the application. Previously this was done using OpenVPN with the configuration in the security group.
However, with moving the EC2 into a private subnet, would I still be able to access the web application? I've tried to do a test on a dev environment following multiple tutorials yet I don't fully understand.
