Elixir OTP

OTP is the operational model for building resilient Elixir systems with supervision, restart strategies, and reusable server processes.

GenServer

GenServer wraps common server behavior and provides a clear protocol for stateful process logic.

Supervision trees

Supervisors restart failed children and define the fault tolerance strategy for the system.

Application structure

Learn how OTP applications organize startup, lifecycle, and service composition.

Practice

  1. Explain the role of a GenServer in one service.
  2. Sketch a simple supervisor with two children.
  3. Write one note about restart strategy trade-offs.
