The best bet if you're using linux is to use LVS. http://www.linuxvirtualserver.org/ I have two directors that balance mail, ftp and www. They run in Direct Routing mode, which is essentially layer 2 load balancing (done at the ethernet mac layer). They both use VRRP failover incase on dies. Using keepalived, http://www.keepalived.org This type of setup can be difficult to get right and you will have to recompile your kernel. If that makes one uneasy, stick with DNS round robin.
