Why use software? I have a hardware load balancer at Softlayer and for $99 bucks a month it's totally worth it.

- modoc 18y agoBecause Softlayer (as much as they rock) don't have failover for those load balancers. You may not need it, but after we had our site downed due to hardware failure of one of their load balancers, we moved to a redundant software based setup. We used HAProxy and Heartbeat2 to provide fully redundant load balancers. On our smaller sites, we actually run the HAProxy and Heartbeat2 on two of the web servers for that cluster, so you don't need dedicated hardware if you don't want it. If you do this, and you're on softlayer, I'd recommend sending the back-channel traffic along the internal network to avoid using 2X your real bandwidth.
