LiteSpeed Web ADC is a high-performance load-balancer application. It is feature-rich, secure, and efficient, offering more flexibility than similarly-priced load balancing software. This makes it an excellent choice for small enterprises looking to scale their applications beyond one server. LSADC gives you improved service speed as well as reliability in case of hardware failure. Manage multiple backend servers, and handle scenarios ranging from a few very heavy sites, to thousands of domains at a time. Learn more about LiteSpeed Web ADC
