Route53 is a managed DNS (Domain Name System).It is a collections of rules and records which helps a client understand ,how to reach a server through its domain name eg

www.exaple.com --------->Route53---------->1.23.474.90

In AWS there are 4 records you should no

1.A:hostname to IPV4 address
2.AAAA:hostname to IPV6 address
3.CNAME:hostname to hostname
4.Alias:hostname to AWS resource

Take for instance a web browser want to access our application hosted on a server with an IPV4 address of 32.99.85.89 .Behind the seen our web browser would make a request to our DNS which is Route53 asking it to give you the location where www.example.com is store. Route53 goes to it records and check where the A records is pointing to, which we set to be an IPV4 address .This then gives our web browser access to the content stored in this server. Why this is possible is because we have mapped a host name to an IP.
