A load balancer is primarily designed to distribute network or application traffic across multiple servers, ensuring no single server becomes overwhelmed, which can lead to slow performance or downtime. Among the options provided, a web server is the type that most benefits from a load balancer due to its role in handling client requests and delivering content over the internet.

Web servers often encounter varying levels of traffic, especially during peak times. A load balancer can efficiently distribute incoming requests to multiple web servers, which helps optimize resource use, enhance response times, and increase the reliability of web applications. By managing traffic, the load balancer can ensure that web servers remain responsive and can scale easily to handle sudden spikes in demand.

While database servers, file servers, and application servers can also benefit from various performance and redundancy strategies, they typically do not require the same level of traffic distribution as web servers. Maintaining data consistency and transaction integrity in database servers, for instance, is more critical than simply balancing traffic. File servers focus on storage logistics, and application servers may manage business logic rather than direct user traffic. Thus, the web server context showcases the specific advantage load balancers provide in terms of traffic management and resource allocation.
