Load Balancer

A system that distributes incoming network traffic across multiple servers, preventing any single server from becoming overwhelmed and ensuring high availability.

When your product goes viral or launches to a large audience, a single server can't handle the traffic. Load balancers allow horizontal scaling, add more servers, distribute the load, stay online.

During a founder's Black Friday launch, traffic spikes 20x. Her platform's load balancer distributes requests across 5 servers automatically, customers experience no slowdown while competitors' sites crash.
