“Maximizing Performance with SAP ERS/ASCS on Azure Files SMB: A Step-by-Step DR Scenario for Windows Application Servers”
DR Scenario for SAP Windows Application Servers with the Focus on ASCS/ERS using Azure Files SMB
Introduction
SAP applications are widely used by businesses throughout the world. To ensure continuous operation, Disaster Recovery (DR) is an important element of an SAP system architecture. Businesses need to consider the robustness of their DR systems in order to maintain business continuity in the event of a disruption. In this blog, we will discuss a DR Scenario for Windows Application servers running on Azure, with a focus on the Availability and Scalability Cluster Service (ASCS) and Enterprise Resource Planning (ERS) components. We will also explore the use of Azure Files SMB for DR.Overview of DR Scenario for Windows Application Servers
The DR scenario for Windows application servers on Azure consists of the following components: * Azure Virtual Machines (VMs) for the application servers
* Azure Files for shared storage
* Azure Site Recovery (ASR) for automated failover and failback of the VMs
Azure Virtual Machines for Application Servers
Azure VMs are used to provide compute power for the application servers. The VMs can be used for both the production and disaster recovery environment. The VMs can be deployed using ARM templates, with the configurations for each VM stored in Azure Storage. This allows for easy deployment and configuration of the VMs.Azure Files for Shared Storage
Azure Files can be used to provide shared storage for the application servers. Azure Files offers the ability to mount the storage as a file share, allowing applications to access the files directly. This can be used to store the application data, as well as the configuration files and scripts.Azure Site Recovery for Automated Failover and Failback
Azure Site Recovery is used to automate the process of failing over to the disaster recovery environment. ASR can be used to replicate the VMs in the production environment to the disaster recovery environment, and provides the ability to failover to the disaster recovery environment in the event of an outage. ASR can also be used to failback to the production environment once the outage has been resolved.ASCS/ERS and Azure Files SMB
The ASCS/ERS components of SAP applications can be deployed on Azure VMs. The ASCS/ERS components are used for high availability and scalability of the application. The application data is stored on Azure Files, which can be mounted as an SMB file share. This allows the ASCS/ERS components to access the application data directly, without having to copy the data between environments.Conclusion
This blog has discussed a DR scenario for Windows application servers on Azure, with a focus on the ASCS/ERS components of SAP applications and the use of Azure Files SMB for DR. Azure VMs are used to provide compute power for the application servers, with Azure Files providing shared storage. Azure Site Recovery is used to automate the process of failing over to the disaster recovery environment. The ASCS/ERS components can access the application data directly from the Azure Files file share. With this DR scenario, businesses can ensure continuous operation of their SAP applications in the event of an outage.
