View instance mix configurations

This article details how to view your instance mix configuration on a virtual machine scale set, including the virtual machine (VM) sizes and the allocation strategy.

Important

Instance mix for Virtual Machine Scale Sets with Flexible Orchestration Mode is currently in preview. Previews are made available to you on the condition that you agree to the supplemental terms of use. Some aspects of this feature may change before general availability (GA).

Prerequisites

Before using instance mix, complete feature registration for the FlexVMScaleSetSkuProfileEnabled feature flag using the az feature register command:

az feature register --namespace "Microsoft.Compute" --name "FlexVMScaleSetSkuProfileEnabled"

It takes a few moments for the feature to register. Verify the registration status by using the az feature show command:

az feature show --namespace "Microsoft.Compute" --name "FlexVMScaleSetSkuProfileEnabled"

View the instance mix configurations

Azure portal

1. Navigate to the virtual machine scale set you want to view.
