3. Use CloudFront

It took minutes to deploy CloudFront distribution. After it deployed, I can request to the Distribution domain name, similar to d1h8c2008a5f6j.cloudfront.net.

Go to Route 53 - Hosted zones - Select the domain - Create record.

Record name: api

Record type: A

Alias: on

Route traffic to Alias to CloudFront distribution

Enter "d1h8c2008a5f6j.cloudfront.net"

Now I can use the api through "https://api.ourcompanylunch.com".
