Episode notes
Fundamentals of SLOs and Error Budgets
- SLOs combine four elements: SLI (metric), objective (value), target (percentage), and time window (duration).
- Error budget is a powerful fifth element representing tolerated unreliability for decision making.
Dining as an SLO Analogy
- Sal uses dining experiences to explain varying expectations similar to user journeys in services.
- Expectations depend on context, order complexity, and busyness, illustrating SLO tailoring importance.
Measure What Matters to Users
- Focus your SLOs on measuring user happiness, not just system health.
- Measure what matters to users to ensure meaningful reliability targets and avoid irrelevant technical metrics.
