Here's how you can direct a domain to your instance:
1. Created a hosted zone in route 53 dashboard and provide the name of the domain you want to use.
2. Your domain must have provided you with a way to edit the nameservers. Save the nameservers provided by the DNS entries into the domain provider panel.
3. Create a recordset of your domain in the hosted zone and give your server's IP(Elastic IP) as value
Note: Make sure the Elastic IP you created is associated with your instance.
