Chapter 8. Regions and Zones

8.1. Introduction to Regions and Zones

With the release of OpenShift Enterprise 2.1, you can group nodes into regions and zones. Regions and zones provide a way for brokers to manage several distinct geographies by controlling application deployments across a selected group of nodes. You can group nodes into zones and group zones into regions. These groups can represent physical geographies, such as different countries or data centers, or can be used to provide network level separation between node environments. Using regions, you can maximize your application performance with less latency by deploying applications closer to your expected users.
Only the system administrator can configure regions and zones, but application developers can create applications in specific regions, view region information when accessing a gear, and can list the regions available. Contact your system administrator, or see the OpenShift Enterprise Administration Guide for more information on regions and zones.
