I think this is really neat. I've never really understood using Serverless platforms for websites and things that process web traffic as there's almost always enough that a "real" webserver is quicker, easier, and cheaper.

However, I've seen many things that run a couple of times a day, or in response to a deployment, or things like that, which often need some compute behind them, but for which setting up a little server and hosting it somewhere just to call it once a day feels like so much unnecessary ceremony.

Does this have a maximum function duration? If so this could still rule out this approach.
