Illustration of a web farm configuration

The following tasks are performed in a web farm configuration:

• The client applications send requests through a firewall to a load balancer. The load balancer distributes requests among application servers.
• The job scheduler services on all of the application servers run; however, only the primary job scheduler processes requests. The other job scheduler services do not accept any requests. Examples of tasks that require the job scheduler service include importing and validation.
• All tasks that do not require the job scheduler service are distributed among the application servers.
