by Mule uses an active-active model to cluster Mule Runtime engines. In Active/Active model both the nodes (assuming cluster have two nodes only), are available to handle traffic and in case, one of them goes down, say node A, then the other one/node B will take over the load from its companion (the process is called failover) and when node A comes back up it will take back it's connections and services from node B (called failback) whereas in Active/Passive model only one server (primary node) handles all the traffic while the other node (secondary server) just sits there ready to take over if the primary node fails.

Anypoint Platform will restart both the servers when Create Cluster is clicked to apply cluster settings. Servers will be not listed under Server panel now, to see them, go to Servers -> Click on Cluster Name.
