I have a couple of frontend servers running on AWS (running pound for SSL termination and Varnish for caching). My backend is at a remote location (not on AWS).
I am looking for the best/fastest way to securely connect AWS with my backend.
I assume the best option would be to setup OpenVPN (but this would also require quite a bit of work/configuration).
Would stunnel be sufficient for this particular situation? Or does anybody have any other suggestions?
