text: Figure 2-14 OpenShift Container Platform architecture 
  
  OpenShift Container Platform is a microservices-based architecture that is composed of 
  decoupled and small units working together. The microservices are categorized by function: 
  REST APIs to change the state of the system, and Controllers, which use the REST API to 
  read the user’s wanted state, and then try to bring the other parts of the system into sync. 
  
  **OpenShift Kubernetes cluster components**
  OpenShift is based on Kubernetes cluster. Kubernetes manages containerized applications 
  across a set of hosts and provides mechanisms for deploying, maintaining, and application 
  scaling.
