Hi all,
Now I have got a Zen cluster up-and-running successfully, I'm turning my
attention to the type of load balancing algorithm to use.
I can see why Round-Robin with persistence is probably the best option
for things like http, every connection is fairly short lived and so the
balance remains good.
Since I want to use Zen for RDP, I think this might not work so well.
Each session can last for anything from 15 minutes up to eight hours and
so by the end of the day a simple round-robin would leave an unevenly
distributed farm.
On our current F5 boxes, we use an algorithm that always picks the
server with the fewest connections, but uses persistence to reconnect in
the event of a problem. Do any of the Zen or Pen modes allow for
something like this? I'm going to try with RR anyway to see if the
problem is big enough to worry about but it would be good to hear what
other people are doing for this kind of farm.
Regards
