Neither DNSSEC on Route53. Plenty of technologies are just not available on 'insert popular cloud provider of today'. That's why not everyone there where everyone-else.
Why the downvotes? Just because I said something negative about DNSSEC? DNSSEC is a bad solution. More well informed minds than HackerNews have come out as to why DNSSEC is a bad idea. I'm not being mean or spiteful. It really isn't going to work.
