The intelligent circuit breaker system adopted by UniAPI is a key component of its high availability architecture. The system protects back-end services through a multi-level fusion strategy: when an API endpoint is detected to have failed 3 times in a row, it will automatically pause sending requests to that node for 5 minutes; when the number of failures reaches 4, the fusion time will be extended to 10 minutes; and if it fails for a total of 9 times, the node will be isolated for 48 hours.
This stepped protection mechanism has three core advantages: 1) giving reasonable recovery time to the failed service; 2) avoiding the failed node slowing down the overall system response; and 3) preventing cascading failures due to the unavailability of individual services. Actual operation data shows that this mechanism can increase the overall system availability from 99% to 99.9%.
Especially noteworthy is that during a meltdown, the system will automatically switch to other available service providers, ensuring that end users do not perceive any abnormal state of the back-end service. This seamless switching capability is an important feature that makes UniAPI superior to simple API gateway products.
This function is especially suitable for financial, medical and other industries that require strict system stability application scenarios.
