 # SAP ASE Azure Virtual Machines DBMS deployment for SAP workload
 
 In this document, covers several different areas to consider when deploying SAP ASE in Azure IaaS. As a precondition to this document, you should have read the document [Considerations for Azure Virtual Machines DBMS deployment for SAP workload](dbms_guide_general.md) and other guides in the [SAP workload on Azure documentation](./get-started.md). This document covers SAP ASE running on Linux and on Windows Operating Systems. The minimum supported release on Azure is SAP ASE 16.0.02 (Release 16 Support Pack 2). It is recommended to deploy the latest version of SAP and the latest Patch Level.  As a minimum SAP ASE 16.0.03.07 (Release 16 Support Pack 3 Patch Level 7) is recommended.  The most recent version of SAP can be found in [Targeted ASE 16.0 Release Schedule and CR list Information](https://wiki.scn.sap.com/wiki/display/SYBASE/Targeted+ASE+16.0+Release+Schedule+and+CR+list+Information).

 Remark: Throughout documentation within and outside the SAP world, the name of the product is referenced as Sybase ASE or SAP ASE or in some cases both. In order to stay consistent, we use the name **SAP ASE** in this documentation.
 
 ## Operating system support
-The SAP Product Availability Matrix contains the supported Operating System and SAP Kernel combinations for each SAP application.  Linux distributions SUSE 12.x, SUSE 15.x, Red Hat 7.x are fully supported.  Oracle Linux as operating system for SAP ASE is not supported.  It is recommended to use the most recent Linux releases available. Windows customers should use Windows Server 2016 or Windows Server 2019 releases.  Older releases of Windows such as Windows 2012 are technically supported but the latest Windows version is always recommended.
