Performance configuration is a critical aspect to consider when preparing for the AZ-140 Configuring and Operating Microsoft Azure Virtual Desktop exam. An efficient configuration guarantees optimal performance for your Azure Virtual Desktop infrastructure, ensuring your team productivity and data security. The course equips you with knowledge and skills on assessing performance requirements, choosing the appropriate configuration, and implementing it to your system.
Session Host Sizing
The first step is to determine the appropriate size for your session host. This usually depends on the number of users and the kind of workloads envisioned. However, Microsoft provides some session host sizing recommendations as shown on the table below:
| User Workload | VM Size | vCPU:RAM ratio |
|---|---|---|
| Light | D2s_v3 | 1:4 |
| Medium | D4s_v3 | 1:4 |
| Heavy | D8s_v3 | 1:4 |
Network Configuration
The ideal network performance for Azure Virtual Desktop depends on the number of users, their geographical distribution, and the apps they would be using. Here are some general recommendations:
- Implement Azure Express Route. This technology could provide more reliable, quicker connectivity.
- Consider implementing Azure Traffic Manager to manage user traffic and ensure users are always connected to the closest Azure region.
- Use Azure Network Watcher to monitor your network performance and troubleshoot any issues that may arise.
Storage and Disk Configuration
A critical part of performance requirements is storage configuration. For Azure Virtual Desktop, the recommendation is to use Premium SSD managed disks for profile containers. For more cost-effective solution, Standard SSDs can be utilized. For the disk configuration, not all users require a personal space. Working out who does and assigning storage wisely is crucial for achieving optimal performance.
Host Scaling
Using Azure Automation and Azure Logic Apps, you are able to link the amount of session hosts you have running in Azure Virtual Desktop to worker needs. During peak hours, more session hosts are created for use by your workers. During slower periods, these unneeded session hosts are shut down to save costs.
Performance Monitoring
Performance monitoring is crucial to ensure your Azure Virtual Desktop infrastructure is running efficiently. Azure Monitor can track performance metrics and diagnose issues.
Profile Containers
FSLogix profile container can significantly improve system performance by offloading user profiles to a separate disk. It could offer better scalability, quicker profile load times, and effective data management.
In summary, calculating and configuring the performance requirements for an Azure Virtual Desktop setup requires careful thought and strategic planning. By using the tools provided within Azure, such as Azure Express Route, Azure Traffic Manager, Azure Network Watcher, and Azure Monitor, optimal performance can be ensured. However, it’s also essential to consider user workload and the kind of apps the Virtual Desktops would be running when setting up the VM size, storage, and disk configurations. Understanding these techniques are imperative to pass the AZ-140 Configuring and Operating Microsoft Azure Virtual Desktop exam.
