Azure Quotas

Having enough quota in Azure to meet your user capacity requirements is crucial. If you do not have enough quotas, teachers will be unable to schedule more exams.

Maintaining your quota follows these steps:

  1. Gather your user capacity requirements

  2. Calculate required quota

  3. Request quota from Azure

  4. Update quota in the Schoolyear Admin Dashboard

Step 1: Gather your user capacity requirements

Section titled “Step 1: Gather your user capacity requirements”

You need to gather the capacity requirements from your education department. You need to find the maximum number of concurrent exam sessions your AVD implementation needs to support.

Keep in mind that exam sessions are considered concurrent when their timeframes overlap. Note that you must consider the deployment and deletion time of each exam as part of their timeframe. The deployment time is what you configure in the AVD Add-on. The deletion time is fixed to 20 minutes.

An exam scheduled from 09:00 until 11:00 will have a timeframe of 06:00 until 11:20, assuming a 3-hour deployment time.

Step 2: Calculate required quota

Section titled “Step 2: Calculate required quota”

To calculate your quota requirement, follow this calculation:

user capacity X CPU cores per student X 1.15

The number of CPU cores you assign per student depends on the VM Size you configure in the AVD Add-on.

Step 3: Request quota from Azure

Section titled “Step 3: Request quota from Azure”

Ensure you have enough quota in your Azure Subscription.

  1. Navigate to the Quotas page in the Azure Portal.

  2. Select the Subscription you dedicated to this implementation

  3. Select the Region you selected for deployments. You can find which region you selected by to the AVD add-on you installed in a previous step, and checking the region of the Base Resource Group shown in the Infrastructure tab.

  4. Search for Standard DSv5 Family vCPUs (or a different CPU type if you are planning on using a different VM type).

  5. Ensure you have enough quota. If you do not, request an adjustment by clicking the pencil icon.

Step 4: Update Quota in Schoolyear

Section titled “Step 4: Update Quota in Schoolyear”

After you requested your quota from Azure, you need to configure this number in the Schoolyear Admin dashboard as well.

  1. Navigate to the Quota page.

  2. Find the azurevms quota for the Subscription you are using.

  3. Update the value to match what is available in Azure.

  4. Click the Save icon.
