Free and Standard pricing tiers for Azure Kubernetes Service (AKS) cluster management
Azure Kubernetes Service (AKS) is now offering two pricing tiers for cluster management: the Free tier and the Standard tier. Both tiers are in the Base sku.
Free tier | Standard tier | |
---|---|---|
When to use | • You want to experiment with AKS at no extra cost • You're new to AKS and Kubernetes |
• You're running production or mission-critical workloads and need high availability and reliability • You need a financially backed SLA |
Supported cluster types | • Development clusters or small scale testing environments • Clusters with fewer than 10 nodes |
• Enterprise-grade or production workloads • Clusters with up to 5,000 nodes |
Pricing | • Free cluster management • Pay-as-you-go for resources you consume |
• Pay-as-you-go for resources you consume |
Feature comparison | • Recommended for clusters with fewer than 10 nodes, but can support up to 1,000 nodes • Includes all current AKS features |
• Uptime SLA is enabled by default • Greater cluster reliability and resources • Can support up to 5,000 nodes in a cluster • Includes all current AKS features |
Important
Uptime SLA has been repositioned as a default feature included with the Standard tier.
The repositioning will result in the following API changes:
Prior to 2023-02-01 API | Starting from 2023-02-01 API | |
---|---|---|
ManagedClusterSKUName | "Basic" | "Base" |
ManagedClusterSKUTier | "Free" "Paid" |
"Free" "Standard" |
"Basic" and "Paid" are removed in the 2023-02-01 and 2023-02-02 Preview API version, and this will be a breaking change in API versions 2023-02-01 and 2023-02-02 Preview or newer. If you use automated scripts, CD pipelines, ARM templates, Terraform, or other third-party tooling that relies on the above parameters, please be sure to update the API parameters to use "Base" with "Free" or "Base" with "Standard" before upgrading to the 2023-02-01 and 2023-02-02 Preview API or newer API versions.
For more information on pricing, see the AKS pricing details.
Uptime SLA terms and conditions
In the Standard 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 and Standard tier are available in public regions and Azure Government regions where AKS is supported.
- Free tier and Standard tier are available for private AKS clusters in all public regions where AKS is supported.
Before you begin
Azure CLI version 2.47.0 or later and configured. Run az --version
to find the version. If you need to install or upgrade, see Install Azure CLI.
Create a new cluster in the Free tier or Paid 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 commands below show you how to create a new resource group named myResourceGroup and a cluster named myAKSCluster in that resource group in each tier.
# Create a new AKS cluster in the Free tier
az aks create --resource-group myResourceGroup --name myAKSCluster --tier free
# Create a new AKS cluster in the Standard tier
az aks create --resource-group myResourceGroup --name myAKSCluster --tier standard
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"
},
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 to the Free tier
az aks update --resource-group myResourceGroup --name myAKSCluster --tier free
# Update an existing cluster to the Standard tier
az aks update --resource-group myResourceGroup --name myAKSCluster --tier standard
This process takes several minutes to complete. When finished, the following example JSON snippet shows updating the existing cluster to the Standard tier in the Base SKU.

"sku": {
"name": "Base",
"tier": "Standard"
},
Next steps
- Use Availability Zones to increase high availability with your AKS cluster workloads.
- Configure your cluster to limit egress traffic.
