Load balancers enhance system reliability by monitoring server health and automatically redirecting traffic away from failing instances to operational ones.
A load balancer improves uptime by continuously monitoring the health of backend instances and distributing traffic only to those that are responsive. If an instance fails a health check or becomes unreachable, the load balancer automatically removes it from the routing pool and redirects traffic to healthy instances. This failover mechanism prevents outages caused by a single point of failure and ensures that applications remain accessible even during maintenance, crashes, or unexpected server issues.
With a Vultr Load Balancer, this process is automated through configurable health checks and traffic distribution policies. By eliminating single points of failure and spreading requests across multiple instances, Vultr Load Balancers increase the reliability and availability of your applications.
