Services That Require Unique Names

Hi,

I understand you would like to know the AWS services that require unique names convention like S3.

No, but I would say it depends. Just like S3 have globally bucket unique bucket names, cognito user pool domains are unique within a region. S3 designed in such a manner because it is widely used for hosting public websites just like domain names, some other AWS services are associated with the region only i.e. within a region you can't have resources with the same name.

If any, the AWS documentation will also detail any naming rules and convention for services that are globally unique or region based.

I hope this helps. Let me know if I answered your question by up voting my response as accepted or if you have any follow-up.

Kind regards, Ahmed
