If you had 1000 domains, you'd pay $110/month, not $500.   The first 25 
domains at $0.50/month each, after that it's $0.10.   And that's based 
on the publicly available pricing -- they have special pricing if you're

Including queries, if each hosted domain had a million queries a month, 
your total bill would $310.

That's probably a high estimate because it doesn't account for the >500 
domain special pricing and your average registrar-hosted domain doesn't 
get anywhere near 1M queries a month.  Your actual bill would probably 
be significantly less.

If you were to use c4.large instances, it would cost just under 
$400/month to have 6 instances spread across 2 regions with 3 AZs each, 
after instances, load balancers and bandwidth.  That's assuming you do 
the discounted 1-year, no-upfront-fee term on the instances.

And you're still not as redundant or fast as Route 53, which is anycast 
from way more than 6 places.

The math gets a little trickier when we start looking at labour costs 
for both initial development of your platform and ongoing maintenance, 
but from strictly an infrastructure cost perspective, I don't think the 
claim that it would cost "far less" to run your own infrastructure is 
necessarily true for a registrar-doing-hosting scenario.
