Opening wroclove.rb 2018 lightning talk by a 23-year-old speaker exploring the serverless buzzword and how to connect it with Ruby. Walks through the evolution IaaS → CaaS (ECS) → PaaS (Heroku) → FaaS (serverless), arguing FaaS reduces operational cost, removes the need for DevOps, scales to the provider's limits, and encourages better code (faster code = cheaper). Live demo creates a 'bills' app with two functions (create bill, list bills) in Ruby-like code, but notes most FaaS providers don't yet support Ruby. Ends with a call to sign a petition at serverlessforruby.org (transcribed 'services for Ruby dot org'), which already has ~seven signed developers.
