![]() Ensure that you choose VMs that are certified for SAP workloads. Azure Virtual Machines: Select appropriate Azure Virtual Machine (VM) size and configuration that meets the SAP system requirements.*Credit by Leon Davis (Snr SAP Cloud Solution Architect in Microsoft Partner Success Organisation) Compute Support prerequisites: to ensure full supportability and optimal performance of SAP systems on Microsoft Azure Virtual Machine Service, refer to SAP Note 2015553 – SAP on Microsoft Azure: Support prerequisites for support prerequisites that have to be met.įigure 1 – Example SAP S/4HANA on Linux – Azure AvZones Architecture Diagram.PowerShell script – Avzone-Mapping script can be used to find out the mapping of the new subscription relative to the old subscription. You want to make sure to repeat this exercise for each of your Azure subscriptions if there’s more than one subscription. Azure subscriptions are automatically assigned this mapping at the time a subscription is created. Physical zone Logical zone mapping: Physical zones are mapped to logical zones in your Azure subscription.Another alternative is pre-provision application servers in the secondary zone, which will remain shut down until required. In this scenario, you can leverage zone to zone Azure Site Recovery (ASR) to replicate your application servers into the secondary zone. Active/Passive: The only difference to an active/active deployment is that your active SAP application servers are running in only one zone at any point in time.Whilst SAP Central Services and DBMS layer are also deployed across two zones, only one will be active at any point in time. The same is true for the DBMS layer, which will be deployed across the same zones as SAP Central Service. The SAP Central Services instance that uses enqueue replication will be deployed between two zones. At any point of time, there will be active application servers running in a minimum of two zones. Active/Active: This deployment architecture is called active/active because you deploy your active SAP application servers across two or three zones.For more information, see SAP workload configurations with Azure Availability Zones for SAP on Azure zonal deployment reference architecture. Consider factors such as the number of SAP application servers, database servers, Azure Load Balancers, and any other components required for your SAP deployment. Architecture Planning: Work closely with your SAP and Azure architects to design a robust and high-availability architecture that leverages Azure Availability Zones.All architectures start with defining your primary and DR regions, but note that not all Azure regions support Availability Zones: Azure regions currently support availability zones. Region Choice: Refer to my colleague Etienne Dittrich’s blog SAP on Azure: Quantifying your Region Choice.When deploying SAP workloads across Azure Availability Zones, here are some guidelines to follow: Quick guide for deploying SAP with Azure Availability Zones Note that deploying SAP workloads requires collaboration between your SAP and Microsoft Azure teams to align with SAP’s specific requirements and best practices. By adhering to these guidelines, you can ensure the resilience, scalability, and optimal performance of your SAP systems on Azure. These guidelines cover various aspects, including architecture planning, compute, storage and network. ![]() ![]() In this blog, we will outline some best practices to follow when deploying SAP workloads across Azure Availability Zones. By strategically distributing your SAP components across zones, you can protect your SAP systems from zone-level failures and provide a robust infrastructure for uninterrupted operations. Azure Availability Zones provide physically separate data centres within an Azure region, each with its own power, cooling, and networking infrastructure. ![]() Deploying SAP workload across Azure Availability Zones ensures high availability and fault tolerance for your mission-critical business applications. ![]()
