How do I link a domain to AWS EC2?

Question

Domain Name System

Actually a subject. They advised me about a free server on AWS, everything was set up, everything works.
There is only one "but". How can I link a domain to the site that I transferred to Amazon?
I was casually told about DNS at Yandex, but I didn’t understand anything. What to do and how to be?

Answer 1

In the Amazon panel:
Create a new Elastic IP.
Bind the generated IP to the Instance.
In the domain control panel:
Create an entry for domain A pointing to the attached Elastic IP.

Answer 2

Create a new Elastic IP for the server and write this IP in the DNS settings.
