Summary and Quiz on Designing for Chaos

Summary

This section has provided a basic understanding of how to write tooling that provides safety in the face of chaos. We have shown how circuit breakers or exponential backoff can save our network and services from overload when unexpected problems occur. We have shown how rate-limiting automation can prevent runaway workflows before responders can react. We have learned about how tool scoping via a centralized policy engine can provide a second layer of safety without overburdening our developers. We have learned the importance of idempotent workflows to allow workflow recovery. And finally, we have conveyed how an emergency-stop system can be utilized by first responders by quickly limit damage to automation systems while investigating a problem.
