Multi-Region Keys in AWS Payment Cryptography
AWS announced Multi-Region Keys in AWS Payment Cryptography. You can read the official post here: https://aws.amazon.com/blogs/security/multi-region-keys-a-new-approach-to-key-replication-in-aws-payment-cryptography/ This was a meaningful launch because it crossed one of the boundaries AWS takes very seriously: Region isolation. Replicating payment cryptographic keys across Regions meant moving highly sensitive customer material across a boundary that is normally treated as a hard line. That required a lot of design review, security scrutiny, and approvals. Moving critical customer data across Regions is not something anyone treats casually.
