Concepts
-
Plan your architecture:
Determine the number of VMs required for your SAP workload and identify the required roles for each VM, such as an application server, database server, or web server.
-
Create an availability set:
In the Azure portal, navigate to the Azure Portal > Virtual Machines > Availability Sets, and click on “Add” to create a new availability set. Provide a name, select the appropriate subscription and resource group, and choose the desired fault domains and update domains based on your requirements.
-
Create VMs within the availability set:
While creating VMs for your SAP workload, ensure you select the availability set you created in the previous step. Repeat this process for all the required VMs.
-
Configure load balancing:
To distribute incoming network traffic across multiple VMs, you can configure Azure Load Balancer or Azure Application Gateway. This helps ensure scalability and high availability for your SAP applications.
Availability Zones:
-
Check availability zone support:
Ensure that the Azure region you plan to use supports availability zones. Refer to the Azure documentation for the list of regions that provide availability zone support.
-
Plan your architecture:
Similar to availability sets, determine the number of VMs required for your SAP workload and identify the roles for each VM.
-
Create a virtual network (VNet):
Navigate to the Azure portal > Virtual Networks > Add and create a new VNet with the desired address range and subnet configuration.
-
Create availability zone resources:
While creating VMs, select the desired availability zone for each VM. Ensure that all the VMs are deployed across different availability zones within the same region.
-
Configure load balancing:
Similar to availability sets, configure Azure Load Balancer or Azure Application Gateway to distribute network traffic across VMs deployed in different availability zones. This helps ensure high availability and scalability for your SAP applications.
By leveraging availability sets or availability zones, you can design and deploy highly available SAP workloads in Azure. Remember to follow best practices provided by Microsoft and SAP to optimize performance and availability.
Note: The above steps provide a general guideline for designing and deploying SAP workloads into availability sets and availability zones. However, it is crucial to consult the official Microsoft documentation related to Azure for SAP workloads for the most accurate and up-to-date information.
