This light web server could serve many thousand concurrent connections! It works great!
look athttp://wiki.codemongers.com/NginxLoadBalanceExamplehttp://blog.kovyrin.net/2006/08/25/haproxy-load-balancer/lang/en/http://blog.kovyrin.net/2006/05/18/nginx-as-reverse-proxy/lang/en/and http://highscalability.com/
Another issue is keeping content synchronizing between apache servers. There are several solutions: NAS\SAN or programbased DRBD http://en.wikipedia.org/wiki/DRBD.
