Product description

Outstanding performance
The appliance - ENTERPRISE is the fastest way to scale your web site. Simply place two Ultra-reliable Load balancer .org appliances (in fail-over mode) between your firewall and your web servers. All web requests are handled by the load balancer and dispatched to individual web servers based on the scheduling algorithm you select. If any web server fails a health check it is immediately taken out of the cluster so that your customers are not affected.
