OpenSHift Architecture

  • Only x86 platforms supported
    • OpenShift runs on either RHEL or Red Hat Enterprise Atomic Host
      • Nodes are instances of RHEL 7 or Red Hat Atomic Host with OpenShift installed
        • Nodes are orchestrated by masters
  • Hybrid approach supports deploying OpenShift instances across all of these infrastructures
  • OpenShift is supported anywhere that Red Hat Enterprise Linux is
