Circuit breakers play an important role in architecturally resilient systems as they provide a safety mechanism for applications and services. Circuit breakers work by monitoring the performance and health of services and applications, and when they detect an error or failure, they "trip" the circuit and prevent further requests from being sent.
This helps prevent cascading failures that can occur when an individual service or application experiences a problem and continues to receive requests, causing overloads and affecting other services and applications. By stopping the flow of requests, circuit breakers allow the affected service or application time to recover and restore normal operation.
Additionally, circuit breakers can help reduce the impact of network failures and other issues by redirecting requests to other healthy services or applications. This helps ensure that users can continue to access critical services and minimizes downtime or disruptions.
Ultimately, circuit breakers are an essential component of architecturally resilient systems as they help improve overall system reliability, availability, and resilience.
