Values presented are the maximum resources available per deployment of a [container group](container-instances-container-groups.md). Values are current at time of publication.
18+
19+
> [!NOTE]
20+
> Container groups created within these resource limits are subject to availability within the deployment region. When a region is under heavy load, you may experience a failure when deploying instances. To mitigate such a deployment failure, try deploying instances with lower resource settings, or try your deployment at a later time or in a different region with available resources.
21+
22+
## Default quota limits
23+
24+
All Azure services include certain default limits and quotas for resources and features. This section details the default quotas and limits for Azure Container Instances.
25+
26+
Use the [List Usage](/rest/api/container-instances/2022-09-01/location/list-usage) API to review current quota usage in a region for a subscription.
27+
28+
Certain default limits and quotas can be increased. To request an increase of one or more resources that support such an increase, please submit an [Azure support request][azure-support] (select "Quota" for **Issue type**).
29+
30+
> [!IMPORTANT]
31+
> Not all limit increase requests are guaranteed to be approved.
32+
> Deployments with GPU resources are not supported in an Azure virtual network deployment and are only available on Linux container groups.
33+
> Using GPU resources (preview) is not fully supported yet and any support is provided on a best-effort basis.
34+
35+
### Unchangeable (hard) limits
36+
37+
The following limits are default limits that can’t be increased through a quota request. Any quota increase requests for these limits will not be approved.

> [!IMPORTANT]

> The maximum resources in a region are different depending on your deployment. For example, a region may have a different maximum CPU and memory size in an Azure virtual network deployment than for a general deployment. That same region may also have a different set of maximum values for a deployment with GPU resources. Verify your deployment type before checking the below tables for the maximum values in your region.
118+
> K80 and P100 GPU SKUs are retiring by August 31st, 2023. This is due to the retirement of the underlying VMs used: [NC Series](../virtual-machines/nc-series-retirement.md) and [NCv2 Series](../virtual-machines/ncv2-series-retirement.md) Although V100 SKUs will be available, it is receommended to use Azure Kubernetes Service instead. GPU resources are not fully supported and should not be used for production workloads. Use the following resources to migrate to AKS today: [How to Migrate to AKS](../aks/aks-migration.md).

> Some regions don't support availability zones (denoted by a 'N/A' in the table), and some regions have availability zones, but ACI doesn't currently leverage the capability (denoted by an 'N' in the table). For more information, see [Azure regions with availability zones][az-region-support].
