20.2. Kubernetes Platform
-------------------------

The following chart illustrates an x0-generated GKE (Google Kubernetes Engine)
network environment for a demo application, initialized by the *x0-kubernetes-installer*.

The primary purpose of the application is to manage large-scale industrial
packaging systems and warehouse relations.

The application is divided into three sub-parts / environments:

1. Packaging Factory (EDI - SAP systems interconnect)
2. Warehouse Android Scanner Devices
3. Web Administration / Application Control Plane
