Building an Observability Platform

Begin with the debugging loop every engineer already uses, then build an observability platform one block at a time. Learn telemetry before tool names; add metrics, logs, traces, profiles, collection, storage, investigation, action, scale, cost, security, and incident evidence progressively.
