So far, we have been talking in abstract terms. In this section, we will give you an overview of the OpenShift architecture. As a result, you will gain a practical understanding of the functioning cloud PaaS infrastructure.
Let's start with a bird's-eye view architecture diagram:
The preceding diagram sketches the layers of OpenShift architecture. Docker runs on top of the operating system and provides layers of containers. Containers are lightweight, standalone, and executable pieces of software (Further reading, link 2) that can be run anywhere on the cloud. Those containers are orchestrated by Kubernetes, which provides a unified view of heterogeneous computing resources. Finally, OpenShift builds on top of Kubernetes, providing developer tools that automate most configuration tasks. If this short description sounded cryptic to you, don...
