Deployment of SAP on Azure typically consists of two major components – SAP Application Server and SAP Database Server. The performance and cost are heavily reliant upon the correct sizing and proper administration of these servers. With SAP on Azure, you can optimize both elements by leveraging services such as Azure VMs for the Application server, and Azure SQL, HANA large instances, etc., for the Database server.
Optimizing the SAP Application Servers
Sizing
Appropriate sizing is the first step towards optimization. The performance of the SAP Application server can be enhanced by selecting the right series and type of VMs. Azure offers several series of VMs like the E-series or M-series that are memory optimized and perfect for compute-intensive workloads of SAP application servers.
Performance Tuning
Performance tuning can significantly improve the efficiency of SAP application servers. A few techniques include:
- Scaling Up or Down: Azure provides the flexibility to adjust the size of your VM based on your workload. If your current size doesn’t meet the performance requirements, you can scale up or down.
- Scaling Out (Horizontal Scaling): Azure also offers horizontal scaling, which means you can add more VMs to distribute the load and enhance the performance.
Optimizing the SAP Database Servers
Sizing
Choosing the right database size or tier is essential for delivering the desired performance. Azure SQL Database offers several service tiers, including General Purpose, Business Critical, and Hyperscale, each designed for different workload requirements.
Azure SQL & HANA Large Instances
Azure SQL is a fully managed relational database service, which significantly reduces the costs involved in managing SQL server databases, making it a perfect choice for SAP databases. On the other hand, for high-performance SAP HANA databases, Microsoft offers HANA large instances, which can go up to 20TB in size.
Cost Saving Measures on Azure
Various cost-saving measures can assist in optimizing the overall Azure for SAP workloads cost.
- Azure Reserved Instances: Reserve your VMs for one or three-year term and save up to 72% compared to pay-as-you-go prices.
- Azure Hybrid Benefit: If you have existing on-premise Windows or SQL server licenses, you can use them in Azure and save up to 40%.
Monitoring and Management
For effective optimization, continuous monitoring and management are crucial. Azure provides several tools such as Azure Monitor, Azure Log Analytics, Azure Cost Management, and Azure Advisor for health monitoring, logs analysis, cost management, and performance recommendations, respectively.
In conclusion, appropriate sizing, performance tuning, and cost-saving measures are pivotal towards optimizing the SAP application servers and databases on Azure. However, constant monitoring and management are equally vital for achieving the desired results. Exam AZ-120 covers these areas and more to ensure a seamless transition and operation of SAP workloads on Azure. It’s recommended to refer to the Azure documentation and take practice exams to get a hands-on experience before the certification exam.

Interview Questions
What is the key benefit of optimizing performance and cost of SAP application servers and databases in Azure?
The key benefit includes improved SAP system responsiveness, cost reduction due to efficient use of resources, and overall better utilization of Azure infrastructure services.
How can Azure Infrastructure-as-a-Service (IaaS) platform help improve performance and reduce cost for SAP applications?
Azure IaaS platform allows for scaling resources on-demand to match workload requirements, thus improving performance. It also offers the benefit of pay-as-you-go pricing, reducing costs as you only pay for the resources you use.
What is the role of Azure Advisor in optimizing resources for SAP applications in Azure?
Azure Advisor analyses resource configuration and usage data to provide personalized recommendations on high-impact actions you can take to optimize your Azure deployments for cost and performance.
Why is it useful to monitor the CPU and memory usage of Azure VMs running SAP workloads?
Monitoring these metrics can help assess if the current VM size is appropriate. If a VM is underutilized, it might be resized to a smaller, less expensive one, without impacting performance thereby optimizing cost.
How does Azure cost management assist in optimizing costs for SAP applications?
Azure Cost Management provides visibility into where spending is accumulating in your Azure resources, helps identify cost-saving opportunities, and provides reports that can be used to show and predict costs.
How does the Azure Automation tool contribute to optimizing SAP workloads?
Azure Automation allows for automating repetitive tasks which helps increase efficiency, reduce errors, and reduce operational costs.
Why is correctly sizing Azure VMs so important for optimizing performance and cost for SAP applications?
Correct sizing ensures you don’t overprovision and pay for unnecessary capacity, or underprovision and risk poor performance. Proper sizing helps balance cost with performance.
What is the role of Azure Reserved Instances in cost optimization?
