Free, Standard, and Premium pricing tiers for Azure Kubernetes Service (AKS) cluster management

Azure Kubernetes Service (AKS) offers three pricing tiers for cluster management: the Free tier, the Standard tier, and the Premium tier. All tiers are in the Base SKU.

Uptime SLA terms and conditions

In the Standard tier and Premium tier, the Uptime SLA feature is enabled by default per cluster. The Uptime SLA feature guarantees 99.95% availability of the Kubernetes API server endpoint for clusters using Availability Zones, and 99.9% of availability for clusters that aren't using Availability Zones. For more information, see SLA.

Region availability

  • Free tier, Standard tier, and Premium tier are available in public regions and Azure Government regions where AKS is supported.
  • Free tier, Standard tier, and Premium tier are available for private AKS clusters in all public regions where AKS is supported.

Before you begin

You need Azure CLI version 2.47.0 or later. Run az --version to find your current version. If you need to install or upgrade, see Install Azure CLI.

Create a new cluster and select the pricing tier

Use the Azure CLI to create a new cluster on an AKS pricing tier. You can create your cluster in an existing resource group or create a new one. To learn more about resource groups and working with them, see managing resource groups using the Azure CLI.

Use the az aks create command to create an AKS cluster. The following commands show you how to create a new cluster in the Free, Standard, and Premium tiers.

# Create a new AKS cluster in the Free tier

az aks create \
    --resource-group $RESOURCE_GROUP \
    --name $CLUSTER_NAME \
    --tier free \
    --generate-ssh-keys

# Create a new AKS cluster in the Standard tier

az aks create \
    --resource-group $RESOURCE_GROUP \
    --name $CLUSTER_NAME \
    --tier standard \
    --generate-ssh-keys

# Create a new AKS cluster in the Premium tier
# LongTermSupport and Premium tier should be enabled/disabled together

az aks create \
    --resource-group $RESOURCE_GROUP \
    --name $CLUSTER_NAME \
    --tier premium \
    --k8s-support-plan AKSLongTermSupport \
    --generate-ssh-keys

Once the deployment completes, it returns JSON-formatted information about your cluster:

# Sample output for --tier free

  },
  "sku": {
    "name": "Base",
    "tier": "Free"
  },

# Sample output for --tier standard

  },
  "sku": {
    "name": "Base",
    "tier": "Standard"
  },

# Sample output for --tier premium

  "sku": {
    "name": "Base",
    "tier": "Premium"
  },
  "supportPlan": "AKSLongTermSupport",

Update the tier of an existing AKS cluster

The following example uses the az aks update command to update the existing cluster.

# Update an existing cluster from the Standard tier to the Free tier

az aks update --resource-group $RESOURCE_GROUP --name $CLUSTER_NAME --tier free

# Update an existing cluster from the Free tier to the Standard tier

az aks update --resource-group $RESOURCE_GROUP --name $CLUSTER_NAME --tier standard

Updating existing clusters from and to the Premium tier requires changing the support plan.

# Update an existing cluster to the Premium tier
az aks update --resource-group $RESOURCE_GROUP --name $CLUSTER_NAME --tier premium --k8s-support-plan AKSLongTermSupport

# Update an existing cluster to from Premium tier to Free or Standard tier
az aks update --resource-group $RESOURCE_GROUP --name $CLUSTER_NAME --tier [free|standard] --k8s-support-plan KubernetesOfficial

This process takes several minutes to complete. You shouldn't experience any downtime while your cluster tier is being updated. When finished, the following example JSON snippet shows updating the existing cluster to the Standard tier in the Base SKU.
