Encryption keys are created in Key Management Service (KMS), not in IAM. Looking at older documentation on other websites, it appears that there used to be an option in IAM that no longer exists in the IAM interface.[1][2]

I think there is still a region or two that offers IAM based keys — but for all other regions this is the OLD way of doing it.
this course is very outdated in some respects — expensive cources with old info 🙁
