Raspberry Pi Cluster with the Power of Elixir
summary
Deploys an Elixir/OTP cluster across Raspberry Pis, runs a Phoenix web API for job submission, and uses Elixir processes to balance work across nodes. Built a background pipeline to generate PDFs from XML pulled from government feeds, with simple node naming, /etc/hosts edits and a cookie for discovery. Observes local runs around 20 seconds and end-to-end time falling to 5 seconds with three nodes. Mentions HAProxy for HTTP load and the setup is demonstrably working.
