I just used crontab as the example already mentioned. There are surely other ways to schedule stuff even in the beam itself. The point was rather that it’s a tradeoff to be made if you reimplement something in elixir (if it doesn’t exist) or if it’s simpler to use OS level tools already existing. It makes sense to move stuff into elixir if the overhead of managing the external system is extensive enough. If not just use the OS level tool until it no longer fits the above premise.
