Concept notes

Why this decision matters

SLO Incident Commander is focused practice for Service objectives and incident command. It explains why each answer is safe, risky, or production-ready.

Command the incident from user impact through durable recovery instead of chasing the loudest chart.

Learning objectives

  • Prioritize user-facing service indicators.
  • Interpret multi-window burn-rate alerts.
  • Define evidence-based mitigation exit criteria.

How to play

  1. Start from the customer outcome.
  2. Select the signal and mitigation with the highest diagnostic value.
  3. Keep the incident open until exit criteria hold.

Scoring

  • Correct command decisions add 250 points.
  • Weak signals reduce simulation indicators.
  • A perfect response scores 1,000.

Backend concept notes

SLIs measure user outcomes while RED and USE organize service and resource evidence.

Error-budget burn translates current failure into urgency across useful time windows.

Common mistakes

  • Paging only on host CPU.
  • Averaging away fast burn.
  • Ending an incident after one green minute.

FAQ

Short answers for how this game fits backend interview and study practice.

Is an SLO the same as an alert threshold?

No. The SLO defines the reliability objective; alerts use windows and burn rates to detect risk to it.

Why use both RED and USE?

RED shows service outcomes while USE helps locate saturation and errors in constrained resources.
