Instrumentation is like adding a flight recorder to your app, emitting telemetry about its internal state. It's how you generate traces, metrics, and logs for observability tools. The main footgun is over-instrumenting, creating noisy and expensive data.
Toil: The Repetitive Work That Kills Engineering Velocity
Toil is manual, repetitive work that scales with your service, stealing time from real engineering. It's the operational treadmill of handling the same alerts or manually running scripts.
Site Reliability Engineering (SRE): Ops as a Software Problem
