Home Resource Center Glossary Load Balancer

A load balancer is a hardware or virtual software device that intelligently distributes application and network traffic across multiple servers. The goal of the load balancer is to make sure that all users are served information as quickly as possible, and that more work gets done in less time. Today’s application delivery controllers (ADCs) offer load balancing technology as one of their features. 

In addition to optimizing server resources, maintaining application availability, and improving application performance, the load balancer provides health monitoring across all connected servers. This capability ensures that servers and application are responding correctly. If, for any reason, the load balancer senses a problem, it removes unresponsive servers from the pool while maintaining a balanced traffic flow.  

While a traditional load balancer satisfied an organization’s requirements two decades ago, they can’t keep up with modern availability, acceleration, and security demands. Application delivery controllers have bridged the gap by providing load balancing plus new content delivery features.
