====== Load Balancing: LSWS + OLS vs. LiteSpeed ADC ======

If LiteSpeed Web Server and OpenLiteSpeed can also be used as load balancers, why is LiteSpeed ADC a better choice?

LiteSpeed Web Server and OpenLiteSpeed use an uncontrollable Round Robin algorithm as their load balancing function. This algorithm rotates between back-end nodes on every access regardless of the load on each node. 

On the other hand, LiteSpeed Web ADC is an advanced load balancer that comes with some impressive features. 

===== LiteSpeed Web ADC Has... =====

...the ability to choose different algorithms (including Round Robin, Least Load, and Least Sessions).

...the ability to specify session ID string and session timeout.

...the ability to insert tracking cookies.

==== Other Impressive Features ====

[[https://www.litespeedtech.com/products/litespeed-web-adc/features/webadc-zero-conf|Zero Configuration]] allows authorized client servers to send their configuration (domains, ip addresses, ports, etc.) to LiteSpeed Web ADC. This feature provides an alternative way to set up load balancing //dynamically// rather than working with the WebAdmin interface.

High Scalability, High Availability IP failover, Cross Datacenter Replication, Cache Data Synchronization, out-of-the box acceleration for Magento and Wordpress, and other features that make LiteSpeed Web ADC the best-of-breed solution on the market.
