Once you get to know it, Mesos is really quite simple: slaves emit events about their capabilities and running processes; masters collect and distribute an inventory of slaves and their processes and of events that occur on slaves. The frameworks (ie. Marathon for long running jobs; Chronos for scheduled jobs) then listen to those inventories/events and ask the Mesos master to add and delete processes from slaves. So Mesos is quite modular.
