Chaos Engineering: Principles, Experiments, and Production Safety
Chaos Engineering tests failure before users ever do. Learn principles, experiment design, and safety stops that keep production tests from becoming outages.
Category
Reliability
These reliability engineering guides cover how to keep systems up and how to recover when they fall. They mix design with process.
Start with high availability. Then disaster recovery covers RTO and RPO. Also, blue green vs canary makes deploys safer.
