Dynamic Load Balancing

Definition

Dynamic load balancing is a method used in distributed computing to allocate tasks or workloads among multiple processors or servers in real-time, ensuring that no single resource is overwhelmed while others remain underutilized. This approach continuously monitors the system's workload and adjusts the distribution of tasks accordingly, optimizing performance and resource use. By efficiently managing how tasks are divided, dynamic load balancing plays a crucial role in improving overall system efficiency and performance.
