    1. **Installer Provisioned Infrastructure (IPI):** On supported platforms, the installer is capable of provisioning the underlying infrastructure for the cluster. The installer programmatically creates all portions of the networking, machines, and operating systems required to support the cluster. Think of it as best-practice reference architecture implemented in code.  It is recommended that most users make use of this functionality to avoid having to provision their own infrastructure.  The installer will create and destroy the infrastructure components it needs to be successful over the life of the cluster.
    2. **User Provisioned Infrastructure (UPI):** For other platforms or in scenarios where installer provisioned infrastructure would be incompatible, the installer can stop short of creating the infrastructure, and allow the platform administrator to provision their own using the cluster assets generated by the install tool. Once the infrastructure has been created, OpenShift 4 is installed, maintaining its ability to support automated operations and over-the-air platform updates.

    - Network Zones have been the widely accepted approach for building security into a network architecture. The general idea is to create separate networks, each with a specific purpose. Each network contains devices with similar security profiles. Communications between networks is highly scrutinized and controlled by firewall rules ([perimeter defense](https://en.wikipedia.org/wiki/All_round_defence)).
    - **Conclusion:** A company’s security organization must be involved when deciding how to deploy OpenShift with regard to traditional network zones. Depending on their level of comfort with new technologies you may have different options. If physical network separation is the only acceptable choice, you will have to build a cluster per network zone. If logical network type of separations can be considered, then there are ways to stretch a single OpenShift deployment across multiple network zones. This post presented a few technical approaches.
