Re: [CentOS] load balancer recommendations
I have, thanks! That one works just fine. Unfortunately, it does load balancing - and that is all. ClearOS, for instance, does a myriad of things but the kind of load balancer I want. And I would like to have it all in one machine. That is another challenge I face. Boris.

It also has methods to place servers into maintenance mode. It doesn't really handle SSL (though they have been working on it for newer versions), but that can be handled by using Apache or nginx as the front-end termination point for SSL, and reverse proxy into haproxy. It also does generic TCP load balancing, but I don't use it so can't comment on that. Also throwing in my vote with HAProxy, as it meets all of the (thus-far listed) requirements of the OP.
