It’s not a “knowledge gap”. I know how to set up databases, queueing/messaging servers, software load balancers, etc., but maintenance takes time and companies pay to save time.
That's true. And that's one of the things that a FaaS/PaaS gives you. Heroku's 24 time limit is perfect for eliminating the problems with starting the environment for each request, but still completely absolves the client from doing the grunt OS maintenance.
