The scale out example in this section relates to a configuration set up as shown in the following graphic:
               	 
            
 
            	 
             
               		 
 
               	 
            
 
            	 
            Implementing a scale out installation involves the following stages. Each of these stages is explained in detail in subsequent
               topics:
               	 
            
 
            	 
             
               		
               - Set up each machine to be used.
                  		
               
- Install 
                  		  Enterprise Server for .NET on each machine in the cluster.
                  		
               
- On each machine in the cluster, configure access to the database server.
                  		
               
- On each machine in the cluster, configure the firewall.
                  		
               
- Test each machine to ensure that it can connect to the region database.
                  		
               
- Set up network load balancing for the cluster, and verify that the cluster operates.
