6.11. Managing Capacity on Broker Hosts

It is highly unlikely that a need to add more broker hosts will arise in terms of capacity. A broker host is typically used to create and delete applications. The majority of developer and end-user traffic, including updates and actual usage of the applications, is handled by node hosts. However, because the process of creating and deleting applications is sporadic, high availability is the main reason to have additional broker hosts. For example, the service at https://openshift.redhat.com only uses four broker hosts in EC2, mainly for high availability.

See the OpenShift Enterprise Deployment Guide at https://access.redhat.com/site/documentation for more information on how to add a broker host.
