Chapter 1. Executive Summary

OpenShift Container Platform is built around a core of application containers powered by Docker, with orchestration and management provided by Kubernetes, on a foundation of RHEL Atomic Host and Red Hat Enterprise Linux. OpenShift Origin is the upstream community project that brings it all together along with extensions, to accelerate application development and deployment.

This reference document provides a comprehensive example demonstrating how OpenShift Container Platform can be set up to take advantage of the native high availability capabilities of Kubernetes and Microsoft Azure in order to create a highly available OpenShift Container Platform environment. The configuration consists of three OpenShift Container Platform masters, three OpenShift Container Platform infrastructure nodes, three to thirty OpenShift Container Platform application nodes, and native Microsoft Azure integration. In addition to the configuration, operational management tasks are shown to demonstrate functionality.

Please note the reference architecture deploys OpenShift Container Platform in the Microsoft Azure public cloud, not the Microsoft Azure Stack version nor the Microsoft National Clouds regional cloud version.

Note

The number of application nodes deployed by this reference architecture has been tested from 3 to 30. The sizing and limits supported by OpenShift Container Platform is explained in Planning document
