Load balancing is vital in server management to distribute traffic efficiently across multiple servers. Its primary purpose is to prevent any single server from becoming overwhelmed, thereby enhancing application performance and ensuring high availability. By intelligently routing user requests, load balancing optimizes resource utilization and minimizes response time, which is crucial during peak traffic periods. Moreover, effective load balancing contributes to system redundancy and fault tolerance, improving overall resilience and user satisfaction through uninterrupted service.
