If your question is aimed more at deploying on a server - it’s standard practice for applications (java, python, ruby etc) to have a watcher that will restart your app if it terminates/crashes - Pharo is no different. This mechanism serves well If a C primitive fails, or your server terminates it for some reason - and the watcher (or even a bash loop), will just restart it.
These days however, others have pointed out that we’re moving into a Docker world where that bit is taken care of with that infrastructure (I think you need an endpoint to monitor your app with, and which reminds me to revisit this with Pharo as the costs have come down I think). Still, monit or equivalent on an Ocean server is $5/m which is darn good value. (You can probably run several small apps with that too).
