The following figure shows an example of the CloudBees CD/RO architecture in a clustered configuration.
![](../_images/cloudbees-diagrams/horizontal-scalability.a86b2d1.png)
In the clustered configuration, a node refers to the machine on which an agent is installed, and a server refers to the CloudBees CD/RO server cluster. In the server status , the load balancer reports only status and error prompts about a specific server.
As shown in the previous diagram, we strongly recommend that you point the web browser to the load balancer, not to the web server.
