[sap-hana-ha]:sap-hana-high-availability.md [sap-suse-ascs-ha]:high-availability-guide-suse.md Azure Virtual Machines is the solution for organizations that need compute, storage, and network resources, in minimal time, and without lengthy procurement cycles. You can use Azure Virtual Machines to deploy classic applications such as SAP NetWeaver-based ABAP, Java, and an ABAP+Java stack. Extend reliability and availability without additional on-premises resources. Azure Virtual Machines supports cross-premises connectivity, so you can integrate Azure Virtual Machines into your organization's on-premises domains, private clouds, and SAP system landscape. This series of articles covers: * Architecture and scenarios. * Infrastructure preparation. * SAP installation steps for deploying high-availability SAP systems in Azure by using the Azure Resource Manager deployment model. > [!IMPORTANT] > We strongly recommend that you use the Azure Resource Manager deployment model for your SAP installations. It offers many benefits that are not available in the classic deployment model.

You also learn about redundant components in Azure, such as SAP application server. ## High-availability architecture and scenarios for SAP NetWeaver **Summary:** In this article, we discuss high availability architecture of an SAP system in Azure. We discuss how to solve high availability of SAP single point of failure (SPOF) and redundant components and the specifics of Azure infrastructure high availability. We also cover how these parts relate to SAP system components. Additionally, the discussion is broken out for Windows and Linux specifics. Various SAP high-availability scenarios are covered as well. **Updated:** October 2017 * [Azure Virtual Machines high availability architecture and scenarios for SAP NetWeaver][sap-high-availability-architecture-scenarios] The article covers both ![Windows logo.][Logo_Windows] **Windows** and ![Linux logo.][Logo_Linux] **Linux**. ## Azure infrastructure preparation for SAP NetWeaver high-availability deployment **Summary:** In the articles listed here, we cover the steps that you can take to deploy Azure infrastructure in preparation for SAP installation.
