Quotas and limits
Azure Container Apps Sandboxes provide fast, secure, ephemeral compute environments designed to scale rapidly.
Azure Container Apps Sandboxes quotas and limits
| Quota or limit | Typical limit per organization | Check your current quota | Request more quota |
|---|---|---|---|
| Concurrent active cores | 500 | View current quota levels | Request more |
| API rate limits | 3,000 requests per minute | Not shown in quota management | Request more |
Concurrent active cores are the total cores allocated to all active sandboxes at the same time. The number of cores allocated to each sandbox depends on its size. For example, an XS sandbox uses 0.25 cores, while an XL sandbox uses 4 cores. Stopped sandboxes do not count toward this quota.
Your organization's quota can differ from the typical limit.
View current quota levels
View your concurrent cores quota in the Azure portal:
- Open My quotas in the Azure portal.
- Select your subscription.
- For Provider, select Azure Container Apps.
- For Region, select the Azure region you want to check.
- Find the Sandbox Cores quota for your organization.
You can also use the Azure CLI to view quota limit and actual usage for a subscription and region. Sign in with az login, then replace <subscription-id> and <region> with your subscription ID and the region where your sandbox groups run.
- Bash
- PowerShell
SUBSCRIPTION_ID="<subscription-id>"
REGION="<region>"
az rest \
--method get \
--url "https://management.azure.com/subscriptions/${SUBSCRIPTION_ID}/providers/Microsoft.App/locations/${REGION}/usages?api-version=2024-03-01"
$SUBSCRIPTION_ID = "<subscription-id>"
$REGION = "<region>"
az rest `
--method get `
--url "https://management.azure.com/subscriptions/${SUBSCRIPTION_ID}/providers/Microsoft.App/locations/${REGION}/usages?api-version=2024-03-01"
API rate limits aren't shown in Azure quota management.
When to request quota
Request more quota before your planned concurrent usage reaches your current core allocation. Reaching the concurrent cores quota will prevent you from creating new sandboxes or starting existing ones.
Request a higher API rate limit if your expected request volume regularly approaches the limit. Requests that exceed the limit can receive an HTTP 429 Too Many Requests response.
Quota increases can require review. Submit a support request before a planned increase in usage, and select Service and subscription limits (quotas) as the issue type.
