You could also look at round robin dns for when your very large and it's required.
you setup your webserver to offload dns to the dns cluster
each server in the cluster contains exactly the same records as the others in the cluster
with round robin dns you would have
two dns records for your name servers pointing to the same name but different ip's
so request one would server from ns1 (node a) and request two would be served from ns1 (node b) (round robin serves the next in order so 1,2,3,4,5 etc untill it runs out and starts again)
