如何在AWS中设置现有域的子域？

Question

I created an Instance (Windows Server 2016) within AWS and the domain URL amazon gave me as below:

ec2-10-212-103-15.us-east-2.compute.amazonaws.com

Then, to create a subdomain I went to Route53 ( https://console.aws.amazon.com/route53/home#Dashboard ) Here is the picture of my configurations:

But I still cannot open http://uat.ec2-10-212-103-15.us-east-2.compute.amazonaws.com/

(Note: The IP is made-up)

What do I need more to do?

Thanks

You're getting it wrong. Route53 is for custom domains you purchase from any of source (GoDaddy, Amazon, Namecheap naming a few).

The URL ec2-10-212-103-15.us-east-2.compute.amazonaws.com you've mentioned isn't the domain name. It is actually DNS to your server. If your instance is not behind a NAT gateway then you can directly access it through ec2-10-212-103-15.us-east-2.compute.amazonaws.com else you need to place a load balancer with public accessibility or place instance behind an internet gateway.
