Solution architecture: SAP on Azure

This architecture represents a distributed 3-tier SAP system running on SQL Server in the Microsoft Azure cloud platform.

This solution is built on the Azure managed services: Virtual Machines and Storage. These services run in a high-availability environment, patched and supported, allowing you to focus on your solution instead of the environment they run in.

Virtual Machines

SAP on Azure requires that you run your SAP workloads on certified Microsoft Azure Virtual Machines. SAP requires at least two vCPUs and ratio of 6:1 between memory and vCPU. The following VMs are currently available for SAP Production workloads. HANA One – DS14_v2, Standalone HANA Database/Data Warehouse/Applications – GS5, BW on HANA – GS5, S/4 HANA – GS5, Business Suite on HANA – GS5. Always reference SAP Applications on Azure: supported products and Azure VM types. (SAP note – 1928533) for the latest information.

Storage

Microsoft Azure storage blobs contain the disks backing the Virtual Machines, providing long-term storage of unstructured data and executable files. Each SAP system will use Microsoft Azure Blob storage.

Premium Storage

Microsoft Azure Premium Storage provides improved throughput and less variability in I/O latencies. For improved performance, Premium Storage utilizes Solid State Disk (SSD) in Azure Storage Nodes and Read Cache that is backed by the local SSD of an Azure Compute Node. Premium Storage can be found in the DS, DSv2, and GS virtual machines. With capabilities of up to 64TB and more than 80,000 I/O operations per second (IOPS), Premium Storage will meet your most critical data needs.
