The author describes their experience building a fully distributed, clustered, privately networked, global game server system using Elixir and the Phoenix LiveView feature. They emphasize that they didn't need to build a JavaScript front-end or an API for transferring data between the front-end and back-end. Instead, they used Phoenix.PubSub and Horde library for process registry. The author also highlights the benefits of hosting their application on Fly.io, which provides private networked connections and multi-region support. They conclude by expressing satisfaction with the results and encouraging others to build more interesting games using this system.
