Feel free to disagree with me: In my mind, serverless functions are akin to database triggers: they do one thing and one thing only, in response to an event.

Feel free to disagree with me: In my mind, serverless functions are akin to database triggers: they do one thing and one thing only, in response to an event. If one tries to make a serverless function do too much, it tends to get somewhat difficult to debug. If one stays within complexity boundaries analogous to that of a database trigger, things may be more manageable. Just as you would not abuse a database trigger to do wacky things, it may be a good idea to not overextend serverless functions.
