Load Balancer
Definition
A load balancer distributes incoming network traffic across multiple servers.
A load balancer acts as a traffic director, managing requests and sending them to available servers in a pool. This prevents any single server from becoming overwhelmed, ensuring that applications remain responsive and reliable. By spreading the workload, load balancing improves performance and availability.
For instance, when many users visit a popular website simultaneously, a load balancer directs their requests to different web servers, preventing a single server from crashing.
This technology is prevalent in web services, application hosting, and cloud computing environments to manage high volumes of user interactions and maintain service uptime.
