What are circuit breakers?

If you haven't heard of circuit breakers before, they are an important pattern that can help you with keeping your service resilient. In short, the circuit breaker pattern is used to prevent additional failures and unnecessary strain to your systems, by controlling and managing access to the failing services.

I have recorded a video and wrote about the pattern in more detail that explains what a circuit breaker is and how does it work in practice when you're running your services in Kubernetes and with a service mesh.

Hope this is helpful to someone – any feedback/suggestions appreciated!
