load balancer

A load balancer is a device or software that distributes incoming internet traffic across multiple servers. Imagine a restaurant with several chefs; the load balancer directs customers to the chef who is least busy, ensuring that no single chef is overwhelmed. This improves performance, enhances reliability, and ensures that if one chef (server) fails, others can still serve customers without interruption. In essence, a load balancer helps manage resources efficiently, maintaining fast and reliable access to websites and applications, especially when demand is high.
