EMR Serverless Supports AWS KMS Customer-Managed Keys
🔒 Amazon EMR Serverless now supports encrypting local disks with AWS KMS customer managed keys (CMKs), enabling customers to adopt CMKs instead of default AWS-owned keys for greater encryption control. You can use CMKs from the same account or from another account and apply them at the application level or per job run and interactive session. This capability is supported on new and existing EMR Serverless applications across all supported EMR release versions and is available in all Regions, including AWS GovCloud (US) and China.
