Hello folks,
I have seen a couple of other posts concerning this question but I am still unclear and wanted to see if there are any new options for 2024.
What would the recommended setup for Stunnel look like for HA (high-availability)? All I need is basically to have two servers, one active and another one stand by and be able to fail over to the standby server when the active one becomes unavailable due to hardware failure, bad vmotion etc. Extra point if this setup offers automatic failover to DR as well, meaning failover to a third server that's also on standby in case of catastrophic failures on the first two.
This almost looks like a load-balancing solution but not really. I say this because I tried to leverage F5 to accomplish this HA scenario and wasn't successful at it because of the way that the F5 performs active checks so often and how noisy that can be for network perimeter security setups.
My main request is the local HA though, I can come up with a solution for DR later on.
Any recommendation is appreciated. Thank you in advance!
