There's a good argument to make that you should never use your application code for running tasks better handled by infrastructure. Eventually you will want an operations team of some kind and they will absolutely hate you for doing this. It doesn't scale, organizationally speaking. Logic? write it in app code sure. How it's triggered or runs? Probably don't go near that. Use your job scheduler (CRON) or cloud infra to do it. Your operations team can port it, scale it, and cost optimize it without breaking a sweat. If more sysadmin / DevOps are hired to help they are going to roast your development team if they can't actually help you. Elixir may be able to glide by some of this given how flexible its process model is - but it's not good general advice.
