We created two S3 buckets in U.S. East and U.S. West, set up automatic replication, and implemented KMS with customer-managed keys for encryption. I encountered some challenges, particularly with versioning and KMS key policies, which I resolved by ensuring the replication rule had the correct permissions. Overall, I highly recommend exploring cross-region replication, especially focusing on getting the KMS key policies right. If you're working with multiple regions, pay close attention to these details!
