Announcing Larger SKUs for App Service Environment v3

1 minute read • By Mads Damgård • December 1, 2022

Our engineering teams have been hard at work to deliver the new larger SKUs on App Service Environment v3. While it seems simple, as it is multiples of the existing SKU sizes, we took the opportunity to make some major adjustments, and build a more flexible backend to allow us to introduce more compute options in the future.

With the addition of these new Isolated V2 SKUs, these are the SKUs available for App Service Environment v3.

SKU Name vCPUs Memory
I1v2 2 vCPUs 8 GB
I2v2 4 vCPUs 16 GB
I3v2 8 vCPUs 32 GB
I4v2 16 vCPUs 64 GB
I5v2 32 vCPUs 128 GB
I6v2 64 vCPUs 256 GB

You can create new plans and scale in the Azure portal with the new SKUs. The new SKUs are not available if you create both App Service Environment and plan as part of creating a new app in the portal, but you can scale up after creating it. Prices may also not be visible in all regions, but are 2x increments as shown in this screenshot.

Larger SKUs on App Service Environment in Azure portal

Download the latest Azure CLI to have support for the new SKUs using az appservice create/update. Note that the command will take about 40 minutes for Windows and 15 minutes for Linux to complete the create/update operation (use the --no-wait parameter to avoid having to wait for the command to finish in the console):

az appservice plan create/update --name <plan name> --sku I5v2 -g <resource-group-name> -e <ase-name or resource-id> --no-wait

To deploy a new plan or update an existing plan using ARM, you can simply just specify the new SKU names. If you use the template below, just replace the values prefixed with REPLACE. For the reserved property, true = Linux, false = Windows.

        "appServicePlanName": "REPLACE-PLAN-NAME",
        "appServicePlanSize": "I4v2",
        "appServicePlanInstanceCount": 1,
        "location": "[resourceGroup().location]",
        "appServiceEnvironmentResourceId": "/subscriptions/REPLACE-SUB-ID/resourceGroups/REPLACE-RG-NAME/providers/Microsoft.Web/hostingEnvironments/REPLACE-ASE-NAME"
    },
    "resources": [
        {
            "name": "[variables('appServicePlanName')]",
            "type": "Microsoft.Web/serverfarms",
            "apiVersion": "2021-03-01",
            "location": "[variables('location')]",
            "properties": {
                "reserved": true,
                "hostingEnvironmentProfile" :{
                    "id": "[variables('appServiceEnvironmentResourceId')]"
                }
            },
            "sku": {
                "name": "[variables('appServicePlanSize')]",
                "capacity": "[variables('appServicePlanInstanceCount')]"
            }
        }
     ]
}

Looking forward to see what you will do with all that power!
