Load balancing improves responsiveness and increases availability of applications. A load balancer distributing the traffic across multiple backend servers using various methods. By balancing application requests across multiple servers, a load balancer reduces individual server load and prevents any one application server from becoming a single point of failure, thus improving overall application availability and responsiveness. Link load balancer.
