      Nah. The point of REST was always to be stateless. It's why rails actually scales and why "scale" as applied to rails was always a joke.

      Pure REST is obviously stateless but what I'd consider a typical rails app is a session-managed web app with predictable URLs, not REST.

      Also (and again, this is an outsider's impression) is that Rails apps assume a shared central database, which serverless apps would not.

      But the difference between a 2010-era Rails app and serverless is operational more than it is architectural.

      A serverless app is assumed to live in a demand-driven infrastructure that can scale instantly to arbitrary numbers of requests.

      It abstracts away an entire layer of operational responsibility, which makes it attractive to people who are comfortable higher up-stack.

      Isn't that pretty similar to deploying a rails app to Heroku? Or is there a nuance I'm missing?

      Serverless apps are expected to run for a few milliseconds at a time (they are billed per ms) and scale instantly from 0 to 000's of rps.

      So similar in concept but at a couple of orders of magnitude faster startup and shorter duration.

      Ok so not quite rails (which uses more like a FastCGI model than CGI) but similar to PHP/CGI?

      (PHP is so sure of its short duration that its GC strategy is "you don't need one" 😄)

          Yes. It would be like a PHP application that you only pay for when it's actively responding to a request.

          Most PHP apps are fcgi nowadays. The cost isn’t too bad. I am also playing with embedding php into rustling to make request startup faster.

          FCGI was an epic hack that kept the "shared-nothing" alive as long as you followed some basic rules. It's what I'm saying Rails did :)
