How to use Route 53 with any domain name, even if it's already registered with a different provider.

In order to use an existing domain name with Route 53, update the registrar with the correct Route 53 name servers, but pre-requisite is to know those name servers. There are two ways to go about getting name servers for the domain name. The first way is to create a public hosted zone. This will give 4 Route 53 name servers and store the zone on those servers. The second way is to create a reusable delegation set. This will give 4 Route 53 name servers and nothing else. It will not create a hosted zone and it will not store any zone information on the servers.
