You can run one or more separate Ambari Server instances running in “standalone” mode. Running “standalone” Ambari Server instances is useful when users who will access views will not have (and should not) have access to that Ambari Server that is operating the cluster. As well, you can run one or more separate Ambari Server instances “standalone” for a scale-out approach to handling a large amount of users. See Reverse Proxy for more information.
