Sometimes you just want an app to stop for a while — a seasonal project between seasons, a demo you're not showing today, something you'd rather pause than delete.
Sleep now, wake later
Pause an app and it stops serving traffic and running its cron jobs, while keeping all of its data intact. Nothing is deleted, nothing is lost. Resume it whenever you like and it's back exactly as it was — same data, same URL, same behaviour.
It's the difference between putting a project on a shelf and throwing it away.
