Haha, this question is a real brainteaser. I'm just picturing the developer trying to figure out the Region by reading tea leaves or something.

C'mon, guys, using Fn::Split on the AWS::StackId is just too much work. Why not keep it simple with the AWS::Region pseudo parameter?

I think dynamically importing the Region by referencing the relevant parameter in AWS Systems Manager Parameter Store is the best option.

Ooh, I'd go with option D. Dynamically importing the Region from AWS Systems Manager Parameter Store seems like a really flexible and future-proof solution.

I personally prefer finding the Region from the AWS::StackId pseudo parameter using the Fn::Split intrinsic function.

I disagree, I believe requiring the Region as a CloudFormation parameter is more reliable.

I think the most efficient way is to use the AWS::Region pseudo parameter. That way, the Region is automatically detected and doesn't need to be manually set as a parameter.
