Elixir: a potion to mix complexity and concurrency in real‑time
summary
Elixir running on the Erlang VM is presented as a practical platform for massive concurrency and real-time systems, using GenServer and supervisors for fault recovery and restart strategies. A Game of Life demo models 100,000 processes (≈2 KB each) and, via Phoenix PubSub and LiveView, shows distribution and end-to-end restarts while demonstrating measured throughput up to 1,000,000 messages/sec on an 8-core VM with ~1–2 GB RAM and ~60% CPU.
