FreeRadius high availability lab

[Alan Buxey]

what is your NGINX load balancer balancing, the RADIUS requests? if
so, does it understand RADIUS?
your SQL entry is a single box...just one single DB or is that an HA
pair or more?  for high availability, you might be better off with
eg REDIS/MoNGO style DB running on the RADIUS boxes themselves (all
data sharded etc).  what sort of load
are you talking about - why the 4 boxes etc - many questions before a
random drawing showing a basic load balanced front end
