Elixir GenServer: Understanding Elixir concurrency model
summary
Explains how Elixir maps to the BEAM VM and OTP framework, then dissects GenServer single-process state by showing the underlying receive loop and how GenServer reduces boilerplate; demonstrates supervisors and supervision trees as the way to restart failed workers; contrasts preemptive scheduling on BEAM with cooperative models; argues that using OTP primitives and links/message passing prevents single-process failures from crashing the system and makes concurrent services maintainable.
