Load balancing in web servers accomplishes the distribution of incoming network traffic across multiple servers. This ensures that no single server becomes overwhelmed, leading to improved performance and availability of applications. By efficiently managing user requests, load balancing enhances coordination, reducing response times and improving user experience. It also contributes to redundancy; if one server fails, traffic can be redirected to others, minimizing downtime. Load balancers can operate at different layers of the OSI model, including the application layer, providing flexibility in many deployment scenarios.
