These services run on all controller nodes and require specific management and constraints for the start, stop and restart actions. Would you recommend setting up haproxy for rabbitmq in 'round-robin' mode, or 'backup'? One could argue that using haproxy in round-robin evenly distributes the load among the haproxy servers, whereas using when rabbit_hosts all traffic tends to hit the first server on the list, and only goes to the second host once the first one drops dead. If we use K-Means clustering we only set the number of clusters or classes we want.
