text: **7.2 Hybrid architecture and multicloud applications: A true**
  **hybrid multicloud feel for the user**
  
  For containers, different architectures do not mean different types of deployments, even in a 
  multicloud environment with different infrastructures. This section gives an example of how 
  two different environments operate on different infrastructures, architectures, and OpenShift 
  versions. Ephemeral containers that do not use persistent volumes are easy to migrate 
  across different Kubernetes environments. 
  
  This section also demonstrates migrating data that is on persistent volumes that are used by 
  persistent application containers across environments to show the complete stack of a truly 
  multicloud hybrid architecture. 
  
  **7.2.1 Multicloud approach by using stateful MongoDB database**
  
  MongoDB is a NoSQL database that is being used widely as a backend for many 
  applications. This scenario was selected because it shows the flexibility of working with 
  containers on IBM Power Systems servers while using multicloud functions, even on stateful 
  applications. 
  
  The intent is to show with simple Yet Another Markup Language (yaml) files that the same 
  user experience can be achieved, even by the administrator of the clusters. The yaml files can 
  even be converted in templates later if needed for self service deployment. The user 
  transparent experience is shown that uses MongoDB Compass client. The on-premise test 
  environment is in Guadalajara (Mexico), the AWS zone is in Ohio (USA), and the client is in 
  New York (US).
