Concurrent applications in Elixir leverage OTP patterns—supervision trees and GenServer—to manage state and fault tolerance. Phoenix adds real-time capabilities through LiveView for interactive UIs. This approach scales to production-grade systems handling thousands of simultaneous processes.

GenServer is an OTP behavior that encapsulates stateful processes in Elixir. It handles synchronous and asynchronous messaging, state updates, and automatic restart on failure through supervision. Use it to manage shared state in concurrent systems reliably.

Yes. Phoenix LiveView enables real-time, interactive interfaces directly from the server using Elixir code, eliminating the need for a separate JavaScript frontend. State updates push to the browser automatically, reducing complexity.

Supervision trees organize processes hierarchically; when a process crashes, its supervisor automatically restarts it according to configured strategy. This self-healing architecture ensures production systems remain available without manual intervention.

OTP isolates failures—one process crash doesn't affect others—and scales lightweight processes to thousands on a single machine. Traditional threading requires manual synchronization and can't match Elixir's fault tolerance and concurrency density.

Prior Elixir experience helps, but this Skill encapsulates OTP, LiveView, and deployment patterns. Familiarity with Mix, testing frameworks, and functional programming concepts accelerates adoption; the Skill teaches production-grade structure.
