Description: Load balancer failover is a critical process in network infrastructure that allows for service continuity by automatically switching to a backup system when the primary system fails. This mechanism ensures that online applications and services remain available, even in failure situations. Failover relies on constant monitoring of server status and network capacity, allowing the load balancer to detect issues and redirect traffic to operational instances. This process not only enhances availability but also optimizes performance by efficiently distributing the workload across multiple servers. In a general context, failover becomes even more relevant, as modern architectures often rely on multiple geographically distributed instances. Implementing this technique is essential to ensure that critical applications do not experience interruptions, which is especially important in business environments where service loss can result in significant losses. In summary, load balancer failover is a fundamental feature that provides resilience and stability to contemporary IT infrastructures.
