It seems to me, it would look an awful lot like a badly organized server application. Kind of like PHP sites were (generally) organized circa 2003.
Speaking of which, isn't PHP like "OG Severless?" In fact, isn't this a more complicated deployment of what you can do with PHP? I don't even care for PHP, but it seems a lot easier than this, and certainly at least as cheap and easy to deploy.
I'm just at loss what the purpose of this is... or how it isn't reinventing a specific set of wheels that everyone already passed on (or already uses for those specific purposes).
