Description: Failover service refers to the process of switching to a backup service instance in the event of a failure. This mechanism is essential for ensuring the availability and continuity of services in cloud computing environments. Failover allows applications to continue functioning without interruptions, even when a part of the system experiences issues. This process involves detecting failures, activating backup instances, and redirecting traffic to these instances, ensuring that users do not experience downtime. Implementing failover is crucial in microservices architectures, where multiple components interact with each other. Additionally, it relies on monitoring and alert practices that allow identifying problems before they affect end users. In the context of cloud computing, failover integrates with other resilience and scalability features, enabling developers to build more robust and reliable applications. In summary, failover service is a vital component for maintaining application operability in the cloud, minimizing the impact of failures and improving user experience.
