Concepts

When deploying SAP workloads on Azure, it can be beneficial to create a custom image of a virtual machine (VM) that contains all the necessary configurations, SAP software installations, and optimizations. This custom image can then be used to provision additional VMs with the same configuration, ensuring consistency and streamlining the process. In this article, we’ll explore the steps to create and deploy a custom image to an Azure VM for SAP workloads.

1. Provision a virtual machine:

Before creating a custom image, you need to provision a VM with the desired configuration for your SAP workload. You can use the Azure portal, Azure CLI, or Azure PowerShell to create the VM. Ensure that you follow the SAP-specific guidelines for VM configurations, such as using premium disks and specific VM sizes recommended by SAP.

2. Prepare the VM:

Once the VM is provisioned, you need to prepare it for the custom image creation. This involves installing the necessary SAP software components and configuring any specific settings required for your SAP workload. Refer to the SAP and Azure documentation for detailed guidance on the preparation steps.

3. Generalize the VM:

Before capturing the custom image, you must generalize the VM to remove any specific configurations or settings that are unique to the VM. Generalizing prepares the VM to be used as a template for creating multiple instances. To generalize the VM, execute the following steps:

  • Connect to the VM through your preferred remote access method.
  • Open a Command Prompt or PowerShell window with administrative privileges.
  • Execute the following command to generalize the VM and shut it down:

sysprep /generalize /oobe /shutdown

4. Capture the VM as a custom image:

After the VM is in a generalized state and shut down, you can capture it as a custom image. Perform the following steps:

  1. In the Azure portal, navigate to the Virtual Machines section and select your VM.
  2. Click on the “Capture” button in the upper menu.
  3. Provide a unique name, resource group, and location for the image.
  4. Click on “Create” to initiate the image capture process. This may take some time depending on the VM’s size and disk configuration.

5. Deploy a VM from the custom image:

Once the custom image is created, you can deploy new VMs based on this image. This allows you to provision additional VMs with the same SAP configuration and settings without going through the entire setup process again. Follow these steps:

  1. In the Azure portal, navigate to the Virtual Machines section.
  2. Click on “Add” to create a new VM.
  3. In the “Basics” tab, select the “Azure Marketplace” option.
  4. Search for your custom image and select it.
  5. Follow the subsequent steps to configure the VM size, networking, and other settings as per your requirements.
  6. Once all the settings are configured, click on “Review + create” and then “Create” to provision the VM from the custom image.

By following the above steps, you can effectively create and deploy a custom image to an Azure virtual machine for SAP workloads. This allows you to streamline the deployment process, ensure consistency across multiple VMs, and simplify the management of your SAP infrastructure on Azure. Remember to follow the SAP and Azure documentation for best practices and specific guidance related to your SAP workload requirements.
