I am big fan of the open source project RunDeck (a.k.a. My Cron Sprawl Killer). I use it on multiple personal projects and have put it in production at my day job (at Rent the Runway).
Rundeck is great when you need something to centralize scheduled jobs, handle multi-step jobs across servers/platforms, or a way to expose common automation tasks. I have quite a bit of experience with Control-M (enterprise solution to solve same problems from BMC) and I prefer Rundeck ease of use/...
