You can also use SWPM to install all components (SAP HANA, the SAP application server, and the ASCS instance) in one single VM, as described in this SAP HANA blog announcement.
This option isn't described in this Quickstart guide, but the issues that you must take into consideration are the same.
All you need to have is an Azure subscription and an SAP user that can be registered with SAP Cloud Appliance Library.
For information on backing up SAP HANA databases on Azure VMs, see: For information on using SAP Cloud Appliance Library to deploy S/4HANA or BW/4HANA, see Deploy SAP S/4HANA or BW/4HANA on Microsoft Azure.
It is not necessary to define any RAID redundancy level because Azure Premium Storage keeps three images of the disks for redundancy.
You can find documentation about deploying, for example, an S/4HANA system through SAP CAL on Azure in this guide.
Also consider the different virtual hard disk (VHD) throughput volumes of the different Azure premium storage disks as documented in High-performance Premium Storage and managed disks for VMs.
You can add more premium storage disks to the HANA DBMS VMs for storing database or transaction log backups.
This guide helps you set up a single-instance SAP HANA on Azure virtual machines (VMs) when you install SAP Net Weaver 7.5 and SAP HANA 1.0 SP12 manually.
The focus of this guide is on deploying SAP HANA on Azure. At this time, Azure VMs are certified by SAP for SAP HANA scale-up configurations only.
However, for SAP HANA DBMS Azure VMs, the use of Azure Premium Storage disks for production and non-production implementations is mandatory.
