Rails on the BEAM
Summary
The article demonstrates running Rails apps on the BEAM using Juntos and QuickBEAM, enabling fault-tolerant, distributed JavaScript runtimes within the Erlang/Elixir ecosystem. It contrasts BEAM with Node.js and Browser approaches, highlights OTP supervision, and explains how distributed pub/sub and hot upgrades reduce downtime. It also outlines an incremental migration path from Rails to Phoenix and related architectural shifts.
