> API server and a static front end – the future? It's not static front-end, but SPA - Single Page Application. It's the part of the larger Serverless / Backend-less computing trend. We already have: - static websites (i.e. served from Amazon S3 or Google Cloud Storage) - static blogs and CMSes - frameworks for SPAs (Ember.js, Angular, etc.) - Firebase and the likes - Amazon Lambda and the likes And yes - Serverless is the future. > Write the back-end initially in RoR or Flask, move it to Elixir or Scala when your servers start crashing. why not to write it in Phoenix/Elixir from the start? I don't think it's any more harder than RoR.
