Posted by UNIXy, 04-11-2012, 01:31 PM A cluster is a group of machines working together in concert to complete a particular task or tasks. It's generic and doesn't reveal the underlying technology. You don't need to know anything about clustering to load balance traffic. I don't know the specifics of your app but you're probably looking at a load balancer that can do round robin across your set of servers and has self healing capabilities. I know Varnish (director) is able to do both. So you might want to read up on it: https://www.varnish-cache.org/trac/wiki/LoadBalancing Regards Joe / UNIXY
