Interesting article. Can you elaborate a little more on why I should consider the best DNS response vs. the fastest response especially when my customers are concerned with first byte times? Also how do your filter chains differ from the likes of DNS Made Easy or DYN and what makes NSOne better?
Nice post on Muut's backend design.
Managing the infrastructures is quite easy with Ansible, Puppet, or whatever your flavor of config management is. You can also take advantage of anycast DNS and GEO targeting by signing up for a free NSOne.net account. That would probably shave $5 off the total.
Looks promising, but might need to add Doozer to the stack as groupcache has an issue with maintaining a list of peers where the cached data is distributed. Definitely worth looking into though.
