When a Unified Broker is run remotely, some components are distributed on separate machines, but connected on the same network.

When a Unified Broker product is distributed remotely, a separate AdminServer and ubroker.properties file must exist on each machine for access by OpenEdge Management or OpenEdge Explorer. And, for WebSpeed, the Unified Broker Client (that is, WebSpeed Messenger) also resides on the same machine as the Web server, and Web clients (that is, browsers) can reside anywhere on the Internet, intranet, or extranet serviced by the Web server.

Regarding a DataServer, the separate database host for a DataServer applies only to WebSpeed or the AppServer. For a DataServer, the Unified Broker host is the DataServer host. The location of the target database management system (DBMS)—either residing on a separate database host or residing on the same machine as the DataServer host—depends on the DataServer and its platform.

Therefore, you can distribute a Unified Broker instance and its management components among three separate machines on the same network.
