Protect services with a circuit breaker at your API gateway

Ngrok's new circuit-breaker Traffic Policy action enhances the reliability of upstream services by rejecting requests when services respond with 500-level error codes and re-evaluating the health of the service before resuming normal traffic. This feature, inspired by electrical circuit breakers, helps prevent cascading failures, save CPU cycles, and improve user experience by blocking problematic requests before they impact the system. Implementing circuit breaking at the API gateway level provides consistent failure handling across services without the need for custom code, and ngrok's Traffic Policy allows flexible configuration of circuit breaker actions. This approach is particularly beneficial for systems with critical external dependencies, high-throughput environments, and microservice architectures. Ngrok's circuit breaker can replace rate limits for protecting service health, and its composable nature enables tailored configurations for cloud and internal endpoints. The circuit breaker action is available with every ngrok account, and users are encouraged to explore ngrok's developer documentation and community support for optimal use and configuration.
