What is a primary advantage of using load balancing?

A primary advantage of using load balancing is that it ensures that no single device is overwhelmed. Load balancing distributes incoming network traffic across multiple servers or resources, allowing each device to handle a portion of the workload. This not only improves the efficiency of resource utilization but also enhances the performance of applications and services, as it prevents any single device from becoming a bottleneck. By balancing the load, it also increases reliability and fault tolerance, as the failure of one device does not lead to system overload or downtime, because the other devices can take over the traffic.

In contrast, while increasing redundancy of devices does enhance system resilience, that is not the primary function of load balancing. Similarly, simplifying network setup and decreasing overall latency in data transfer are benefits that may arise in certain contexts but are not the main purpose of load balancing. The core idea centers around managing traffic effectively to optimize resource use and ensure stability in system performance.
