Description: Failover gateway switching is an essential feature in API gateways that allows for automatic transition to a backup system in the event that the primary system fails. This capability is crucial for ensuring service continuity and minimizing downtime. When an API gateway detects a failure in the primary system, it immediately activates the backup system, ensuring that user requests continue to be processed without interruption. This functionality not only enhances the resilience of applications but also provides a more reliable user experience. Failover can be configured to be automatic or manual, depending on business needs and system architecture. Furthermore, it is fundamental in environments where availability and reliability are critical, such as in cloud services, telecommunications, and online platforms. Implementing this feature requires careful planning and thorough testing to ensure that the backup system operates correctly in the event of a real failure.
