How Cname Records Is Choosen
Example
If you had a domain example.com and these belows are comparison chart between records and target domains:
| Record name | Type | Value/Route traffic to | Target domains |
|———————|——-|——————————————————-|—————————————————————————–|
| *.example.com | CNAME | hoge.cloudfront.net | hoge.example.com, entry.hoge.example.com |
| *.entry.example.com | CNAME | hoge.cloudfront.net | hoge.entry.example.com, hoge2.entry.example.com, hoge.api.entry.example.com |
| *.api.example.com | CNAME | hoge-alb-service-api.ap-northeast-1.elb.amazonaws.com | hoge.api.example.com, hoge2.api.example.com |
In this case, Lambda-Edge works in Cloudfront’s “Behavior” which can work sorting access.
