      Rails apps were explicitly described as "shared nothing" architectures back when I was working on rails.

      By calling serverless highly scalable I did not mean to imply that former web apps do not scale :-)

      i’d guess that JS’s success in serverless is due more to the ability to embed and sandbox it, which makes life easier for hosting providers

      Sandbox in what sense?

      it’s trivial to restrict access to file system and other OS functions, which makes it safer to run other people’s code in your environment

      it’s been a feature of the language from day 0, as opposed to Ruby/Python/etc which aren’t designed for running untrusted code

      Heroku has used Linux sandboxing facilities to implement this concept for ages: https://12factor.net/processes  (Heroku apps are 12 factor)

      "Serverless" postdates LXC and Docker so "easy to sandbox" can't be the distinction, right?

      i think it’s that you can avoid process startup overhead and may even not need to fully sandbox at the OS level

      You still need to sandbox because JS isn't useful without some exposed OS guts and security is hard ;)

          My hypothesis is: 1. Serverless is, more or less, definitionally about JS 2. It's popular because JS is popular and empowering

          I think the extremely fast startup time of a container running node was crucial to the order of magnitude change I mentioned.

          You could have done it with PHP but as you say JS (and node) are more popular with the up-stack devs this appeals to.

          i think the time to market for a serverless JS offering is also just way shorter, because of status of embedding hooks as 1st class citizens

          i just think JS was the prime language to pioneer the serverless space, all the way from the implementation to the community

          In contrast, I think "serverless" as a term means"JavaScript" so this claim is tautological.
