Amazon Route 53 is AWS’s DNS service offering. It is an authoritative DNS meaning that you are able to update your own DNS records. Route 53 even includes a domain registrar similar to GoDaddy. You have multiple record types similar to traditional DNS, the basic ones are A name for ipv4 host names, AAAA for ipv6 host name, CNAME for hostname to hostname, and NS for name servers that answer these DNS queries. You can set up a public hosted zone for DNS queries using public IPs on the internet or if you need an internal DNS you can utilize a private hosted zone. You pay roughly 50 cents per month per zone at the time of writing this. Each DNS record contains the domain/subdomain name, such as example.com, the record type which would be A, AAAA, CNAME, etc, the routing policy for how route 53 should respond to queries, and the TTL, the amount of time the DNS query is cached on the DNS resolvers. This was a brief overview but I plan to get more in depth on this service.
