This document discusses strategies for building and maintaining online games and services using Elixir and Erlang. It recommends adopting Elixir to leverage Erlang's robust ecosystem while improving approachability. Key aspects include using OTP for building distributed systems, leveraging open source tools like OTP, Hex, Mix and open cloud services. Operations are decentralized by having application engineers own infrastructure as code using Terraform and Chef recipes. Adoption is fostered through onboarding, code reviews and making operations everyone's responsibility.
