  12. 12. ARM Template Compatibility ◦ Deploy the same resources to Azure and Azure Stack ◦ Support more complex scenario than CLI Note: ◦ To deploy RHEL with unmanaged disk, you have to upload VHD file to dedicated storage account(s). ARM Template has no direct way to upload or copy VHD files.

  17. 17. Storage Option If Azure Cloud Provider is unavailable, available storage options is limited. Network Storage – not recommended for RDBMS and high load usage (cassandra, etc) ◦ OpenShift Container Storage (formerly Container Native Storage) ◦ external NFS Block Device ◦ Actually, no options other than local device.
  18. 18. Cloud Provider Consideration If Cloud Provider becomes available in OpenShift on Azure Stack, you have to configure Azure service principal. You have to set up Azure Stack with Azure Active Directory (AAD) or Active Directory Federation Service (ADFS) for Identity Store. ◦ features#identity
