Generally Available: Instance Mix for Virtual Machine Scale Sets

We are excited to announce the general availability of instance mix, a new feature designed to optimize your Virtual Machine Scale Set deployments. Instance mix allows you to specify multiple VM sizes within a single Virtual Machine Scale Set, providing greater flexibility and cost efficiency. To further optimize deployments, instance mix allows you to specify an allocation strategy to optimize for price or capacity.  

  

Key Features  

• Flexible VM Combinations: Mix and match various VM sizes within a single VMSS to better align with your workload requirements.  
• Capacity-informed deployments: Optimize for the available capacity in Azure regions/zones with capacity. Optimized for more confidence that you’ll get the capacity requested. For cost-sensitive customers who want to still utilize capacity signals, the lowest. Price allocation strategy takes both factors into account  
• Simplified Management: Manage a diverse set of VMs in a single scale set, reducing the complexity of handling multiple scale sets.  
• Easily scale with a mix of VM offerings: When using Spot Priority Mix, customers can deploy a heterogeneous mix of VM sizes of both Spot and On-Demand pricing in their scale sets.  
• Attain Capacity: By utilizing a diversified mix of VM sizes, customers can tap into a greater pool of capacity, increasing their ability to get the capacity needed.
