Does any one know a simple but good load balancer that can handle 2000 concurrent connections through http? It will be installed on ubuntu server or you can recommend a OS that it will work better with.

Thank you.

I have tried:

  • HAproxy

    Update:

    I host a website that has scripts on it. I get 300+ request per second. I will be spreading the load on 3 servers running ubuntu. I used rackspace load balancer it worked great but I no longer want to use it as I'm being charged for concurrent connections. If it also has some kind of connection throttle would be a plus but not required.

    "Best" by what definition? Please describe your goals, requirements, and use cases in more detail. – kce Dec 20 '11 at 21:52

    Hard to answer what's "best". I haven't had any experience with these at all. But you might want to take a look and make your own evaluation.

    Obviously, you've mentioned HAProxy.

    There is also: http://www.ultramonkey.org/

    varnish - this has a built in load balancer. https://www.varnish-cache.org/trac/wiki/LoadBalancing

    mod_proxy_balancer http://httpd.apache.org/docs/2.1/mod/mod_proxy_balancer.html

    Pound http://www.apsis.ch/pound

    Also check out the load balancing faq which may be of interest. http://www.loadbalancing.org/
