This graphic has an instance administrator at the top that is communicating with the active management instance. The active management instance has an arrow to the standby management instance to show how changes are propagated from the active management instance to the standby management instance. There is a second arrow that is bidirectional showing the communication from the active management instance to the internal network. On the other side of the internal network are three data instances, each with bidirectional arrows from themselves to the internal network. Thus, the active management instance communicates with all three data instances through the internal network.
