Availability
Users must be able to reach the application regardless of failed server sites. In a clustered Web server environment, the load balancer monitors the availability of the Web servers. If a Web server has failed, no more requests are sent to the failed system. Instead, all requests are routed to other, active Web servers. It is also recommended that you ensure high availability of the load balancer system itself to eliminate it as a single point of failure.
