Chaos engineering: controlled experiments for resilience
Chaos engineering validates assumptions by injecting failures into production-like environments in a controlled way.
Start small and safe
Begin with non-customer-facing services and short blast-radius experiments. Define hypotheses and metrics before running an experiment.
Automate rollback and ensure runbooks are available for every experiment.
Culture and learning
Treat failures as learning opportunities and publish concise write-ups after each experiment.
Use findings to improve runbooks, observability, and service architecture.
