GenServer isolates state in a single process, but that state vanishes on crash. Learn the API-callback split, a working counter example, and how to monitor mailbox bottlenecks before they stall your system.
Learn how the one_for_one restart strategy isolates failures in Erlang OTP supervision trees, see a concrete gen_server example, and understand when to use it.
Learn how to send and verify one‑time passwords with Twilio Verify in a Spring Boot app. The guide covers configuration, code snippets, error handling, and cost‑monitoring steps.
Learn how to implement fault-tolerant state management in Gleam using GenServers and Supervisors via the gleam_otp library to build resilient BEAM applications.
Discover how Erlang’s OTP supervision trees and the "Let It Crash" philosophy let you build self‑healing distributed systems without defensive error handling.
Learn how to build a minimal OTP supervision tree in Erlang: requirements, design, trust boundaries, operational checks, failure modes, and when to redesign.
How OTP supervisors restart failed workers: one_for_one vs one_for_all vs rest_for_one, a worked supervisor module with map child specs, intensity/period escalation, and the state-loss and crash-loop mistakes to avoid.
A concise architecture note that outlines requirements, the minimal supervision‑tree design, trust boundaries, operational checks, failure modes, and triggers for redesign when using Erlang/OTP for resilient services.
Supervision strategy is a claim about which Erlang processes depend on which. Pick it from the dependency graph, then confirm it with a deliberate kill on a test node.
