Remote Metastore

In this mode, metastore runs on its own separate JVM. Other processes can communicate with the metastore server by using Thrift Network APIs.

You can also have one more metastore servers in this case to provide more availability. This also brings better manageability/security because the database tier can be firewalled entirely off. Also, the clients no longer need to share database credentials with each Hive user to access the metastore database.
