Azure Container Registry SKUs

Azure Container Registry (ACR) is available in multiple service tiers, known as SKUs. These SKUs provide predictable pricing and several options for aligning to the capacity and usage patterns of your private Docker registry in Azure.

SKU Managed Description
Basic Yes A cost-optimized entry point for developers learning about Azure Container Registry. Basic registries have the same programmatic capabilities as Standard and Premium (such as Azure Active Directory authentication integration, image deletion, and webhooks). However, the included storage and image throughput are most appropriate for lower usage scenarios.
Standard Yes Standard registries offer the same capabilities as Basic, with increased included storage and image throughput. Standard registries should satisfy the needs of most production scenarios.
Premium Yes Premium registries provide the highest amount of included storage and concurrent operations, enabling high-volume scenarios. In addition to higher image throughput, Premium adds features including geo-replication for managing a single registry across multiple regions, content trust for image tag signing, and firewalls and virtual networks (preview) to restrict access to the registry.
Classic (not available after April 2019) No This SKU enabled the initial release of the Azure Container Registry service in Azure. Classic registries are backed by a storage account that Azure creates in your subscription, which limits the ability for ACR to provide higher-level capabilities such as increased throughput and geo-replication.


The Classic registry SKU is being deprecated, and will be unavailable after April 2019. We recommend using Basic, Standard, or Premium for all new registries. All existing Classic registries should be upgraded prior to April 2019. For upgrade information, see Upgrade a Classic registry.

The Basic, Standard, and Premium SKUs (collectively called managed registries) all provide the same programmatic capabilities. They also all benefit from image storage managed entirely by Azure. Choosing a higher-level SKU provides more performance and scale. With multiple service tiers, you can get started with Basic, then convert to Standard and Premium as your registry usage increases.

SKU feature matrix

The following table details the features and limits of the Basic, Standard, and Premium service tiers.

Geo-replication N/A N/A Supported
Content trust N/A N/A Supported

1The specified storage limits are the amount of included storage for each tier. You're charged an additional daily rate per GiB for image storage above these limits. For rate information, see Azure Container Registry pricing.

2ReadOps, WriteOps, and Bandwidth are minimum estimates. Azure Container Registry strives to improve performance as usage requires.

3A docker pull translates to multiple read operations based on the number of layers in the image, plus the manifest retrieval.

4A docker push translates to multiple write operations, based on the number of layers that must be pushed. A docker push includes ReadOps to retrieve a manifest for an existing image.

Changing SKUs

You can change a registry's SKU with the Azure CLI or in the Azure portal. You can move freely between managed SKUs as long as the SKU you're switching to has the required maximum storage capacity. When you switch to one of the managed SKUs from Classic, you cannot move back to Classic--it is a one-way conversion.

Azure CLI

To move between SKUs in the Azure CLI, use the az acr update command. For example, to switch to Premium:

az acr update --name myregistry --sku Premium

Azure portal

In the container registry Overview in the Azure portal, select Update, then select a new SKU from the SKU drop-down.

Update container registry SKU in Azure portal

If you have a Classic registry, you can't select a managed SKU within the Azure portal. Instead, you must first upgrade to a managed registry.
