The future of cloud programming

168 views

Published on

In this talk we will cover:
1. Using concurrency to maximize hardware (Elixir, Clojure, Haskell)
2. Serverless technologies for backend architecture (Amazon AWS Lambda, Microsoft Azure Cloud Functions)
3. BaaS – Backend as a Service (Google Firebase, etc)
