Previously requiring manual custom domain setup per broker and lacking support for KRaft mode, Amazon MSK Provisioned clusters gained the ability to define one custom domain name at the cluster level. This configuration automatically propagates to all brokers, easing cluster migrations, failovers, and scaling without reconfiguration.

This capability is supported on both ZooKeeper- and KRaft-managed clusters and persists through operational changes. It benefits organizations needing consistent endpoints for security, compliance, or network load balancing. The feature is available at no extra cost in all AWS Regions with Amazon MSK Provisioned service.
