Bring Back the Power of BEAM Deployments with DeployEx
summary
A tool called DeployEx is an Elixir-based orchestrator that runs on the host, watches an S3 bucket for new mix release packages, and performs either full restarts or hot upgrades via generated relup/appup files; it uses the AAC library to spawn and monitor OS processes, connects apps over OTP (mTLS supported), exposes a LiveView dashboard with tracing and Observer-like inspection, and installs via systemd/terraform. A historical pain point is a strict 50 milliseconds failover requirement that containers and Linux scheduling previously missed.
