Architecture of a CloudBees Flow Cluster

1 minute read
The following figure shows an example of the CloudBees Flow architecture in a clustered configuration.

In the clustered configuration, a node refers to the machine on which an agent is installed, and a server refers to the CloudBees Flow 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.
