Chaos Engineering

Principles

1. Build a Hypothesis: Define expected behavior
2. Minimize Blast Radius: Start small
3. Run in Production: Real conditions matter
4. Automate: Make experiments repeatable
5. Minimize Impact: Have abort conditions

Experiment Process

1. Steady State: Define normal metrics
2. Hypothesis: "System will maintain X under condition Y"
3. Introduce Variables: Inject failure
4. Observe: Compare to steady state
5. Analyze: Confirm or disprove hypothesis
