A load balancer is a device that acts as a reverse proxy and distributes network or application traffic across a number of servers. Load balancers are used to increase capacity (concurrent users) and reliability of applications. They improve the overall performance of applications by decreasing the burden on servers associated with managing and maintaining application and network sessions, as well as by performing application-specific tasks.

The Technology Platform Services team in ITS-Enterprise Infrastructure offers load balancing services to select enterprise applications and workloads. The capability exists to provide DNS load balancing, Layer 4 & Layer 7 load balancing, or both.
