+APEX can be clustered in various ways.
+The following figure shows a few of these clustering options.
+Cluster, engine and (policy) executors are named UPec (universal policy cluster), UPe (universal policy engine, APEX engine) and UPx (universal policy executor, the APEX internal state machine executor).
