Platform 3 depicts an HA Controller pair with a remote Events Service cluster and EUM Server. The Events Service cluster contains an API Store on all nodes. The cluster must have three or more nodes.

Platform 4 depicts a single monitoring Controller. This Controller monitors the HA pair in platform 3 by receiving metrics via connection from the App and Machine Agents. See Manage a High Availability Deployment for more information.

Platform 5 depicts a single shared Events Service. A shared Events Service can connect to multiple Controllers from other platforms, minimizing required maintenance and cost. See Events Service Deployment for more information.
