Explanation

AWS KMS multi-Region keys are designed exactly for this use case: the same logical key can be replicated and used in multiple Regions, while AWS manages the underlying key infrastructure. You can control access with IAM policies using ABAC (tags and condition keys) and avoid managing key material, clustering, or cross-Region synchronization yourself, giving you global encryption with the least operational overhead.
