Load balancing is a research field and methodological approach concerned with distributing workloads across multiple computing resources, network links, or other system components. It investigates strategies, algorithms, and system architectures designed to optimize resource utilization, minimize response time, maximize throughput, enhance availability, and ensure fairness by directing incoming requests or tasks to the most appropriate available resource. Its significance lies in improving the performance, scalability, and reliability of distributed systems and infrastructure under varying demand conditions.
