Amazon MSK Now Lets You Set Custom Domain Names Cluster-Wide
Amazon MSK Provisioned clusters now support configuring custom domain names at the cluster level for both ZooKeeper and KRaft modes, automatically applying them to all brokers without manual per-broker setup. This feature simplifies migrations, failovers, and scaling while maintaining persistent endpoints across all AWS regions where MSK Provisioned is available—no extra costs involved.
