Service mesh circuit breaker

Abstract
Site Reliability Engineers are at the center of two tensions: On one hand, they need to respond to alerts within a short time, to restore a non-functional system. On the other hand, short response times is disruptive to everyday life and lead to alert fatigue. To alleviate this tension, many resource management mechanisms are proposed handle overload and mitigate the faults. One recent such mechanism is circuit breaking in service meshes. Circuit breaking rejects incoming requests to protect latency at the expense of availability (successfully answered requests), but in many scenarios achieve neither due to the difficulty of knowing when to trigger circuit breaking in highly dynamic microservice environments.
