UpdateStack permission to IAM principles that are denied SetStackPolicy

CIn the AWS CloudFormation template, set the AWS::RDS::DBInstance's DBInstanceClass property to be read-only

I'm not sure about option A. I think option D could also work by canceling the update if the RDS instance is being changed.

I agree with Thersa. Option A seems like the most straightforward way to avoid this issue in the future.

I think option A is the best choice. By limiting the instance type options, we can prevent accidental changes.
