Learn these 4 Chaos Engineering Principles Before You Break Anything | Resilience Testing | Harness

Want to start chaos engineering? Don't randomly break stuff and hope for the best.

Real chaos engineering starts with defining your system's steady state metrics like latency, throughput, and error rates. Then you form a clear hypothesis about what should happen when failures occur. Next, you inject controlled failures, starting small with single pod kills or network drops, not production meltdowns. Finally, you limit the blast radius by running experiments in safe environments first.

The goal isn't destruction. It's building confidence that your distributed systems can survive real-world failures without taking down your users.
Chaos engineering is the second pillar of resilience testing. Master it and you'll sleep better during on-call rotations.
