Hi, DNS Round Robin (DRR) permits to do cheap load balancing (distribution is a better term). It has the pro of permitting infinite horizontal scaling. The con is that if one of the web servers goes down, some clients continue to use the broken IP for minutes (min TTL 300s) or more, even if the DNS implements fail-over. An Hardware Loa...
