Latency is critical for DNS. Literally everything else an application
does stalls behind completion of the DNS lookups.

Everything else being equal, virtuallized infrastructure will always
exhibit higher latency than bare metal. Always.

I don't know their implementations well. I would hope they run the
underlying DNS servers on bare metal rather than leveraging their VM
infrastructure. I would worry that they offer all sorts of extra
features which are -single source-. If you pick Route 53 and your
customers get used to those features you may find yourself locked in
at Amazon's mercy.
