| 13 | +# Resource availability & quota limits for ACI |
| 14 | + |
| 15 | +This article details the availability and quota limits of Azure Container Instances compute, memory, and storage resources in Azure regions and by target operating system. For a general list of available regions for Azure Container Instances, see [available regions](https://azure.microsoft.com/regions/services/). |
| 16 | + |
| 17 | +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/location/listusage) 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. |
| 38 | + |
| 39 | +| Resource | Actual Limit | |
| 40 | +| --- | :--- | |
| 41 | +| Number of containers per container group | 60 | |
| 42 | +| Number of volumes per container group | 20 | |
| 43 | +| Ports per IP | 5 | |
| 44 | +| Container instance log size - running instance | 4 MB | |
| 45 | +| Container instance log size - stopped instance | 16 KB or 1,000 lines | |
| 46 | + |
| 47 | + |
| 48 | +### Changeable Limits (Eligible for Quota Increases) |
| 49 | + |
| 50 | +| Resource | Actual Limit | |
| 51 | +| --- | :--- | |
| 52 | +| Standard sku container groups per region per subscription | 100 | |
| 53 | +| Standard sku cores (CPUs) per region per subscription | 100 | |
| 54 | +| Standard sku cores (CPUs) for K80 GPU per region per subscription | 0 | |
| 55 | +| Standard sku cores (CPUs) for V100 GPU per region per subscription | 0 | |
| 56 | +| Container group creates per hour |300<sup>1</sup> | |
| 57 | +| Container group creates per 5 minutes | 100<sup>1</sup> | |
| 58 | +| Container group deletes per hour | 300<sup>1</sup> | |
| 59 | +| Container group deletes per 5 minutes | 100<sup>1</sup> | |
| 60 | + |
| 61 | +## Standard Core Resources |
| 62 | + |
| 63 | +### Linux Container Groups |
| 64 | + |
| 65 | +By default, the following resources are available general purpose (standard core SKU) containers in general deployments and [Azure virtual network](container-instances-vnet.md) deployments) for Linux & Windows containers. |
| 66 | + |
| 67 | +| Max CPU | Max Memory (GB) | VNET Max CPU | VNET Max Memory (GB) | Storage (GB) | |

| 72 | + |
| 73 | +### Windows Containers |
| 74 | + |
| 75 | +The following regions and maximum resources are available to container groups with [supported and preview](./container-instances-faq.yml) Windows Server containers. |
| 76 | + |
| 77 | +#### Windows Server 2019 LTSC |
| 78 | + |
| 79 | +> [!NOTE] |
| 80 | +> 1B and 2B hosts have been deprecated for Windows Server 2019 LSTC. See [Host and container version compatibility](/virtualization/windowscontainers/deploy-containers/update-containers#host-and-container-version-compatibility) for more information on 1B, 2B, and 3B hosts. |
| 81 | +
|
| 82 | +The following resources are available in all Azure Regions supported by Azure Container Instances. For a general list of available regions for Azure Container Instances, see [available regions](https://azure.microsoft.com/regions/services/). |

| 106 | +## Next steps |
| 107 | + |
| 108 | +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**). |
