How do you gain confidence that a system is behaving as designed and identify vulnerabilities before they become outages? You may have thought about using chaos engineering for this purpose, but it’s not always clear what that means or if it’s a good fit for your system and team.
My experience at Netflix has led me to embrace chaos engineering to build more resilient distributed systems. I will share examples of chaos experiments which identified problems and built confidence in our resilience mechanisms, as well as several challenges, lessons, and benefits we have encountered while scaling chaos engineering across Netflix.
Key Takeaways

  1. How Chaos experiments complement other types of testing.
  2. How your perspective of Chaos engineering changes as your role and services evolve.
  3. How Chaos engineering can be used to gain confidence in platforms, configurations, and resiliency mechanisms.
  4. Lessons scaling Chaos engineering safely and effectively.
