GA: Spot Priority Mix
Published date: 09 March, 2023
Azure is excited to announce the General Availability of Spot Priority Mix, a new feature for Virtual Machine Scale Sets (VMSS) with Flexible Orchestration Mode enabled. With Spot Priority Mix, customers can now mix spot and standard virtual machines in their Flexible scale set, providing the high availability of standard virtual machines and the cost savings of Spot virtual machines. This feature also allows customers to autoscale their scale set with a percentage split of Spot and standard virtual machines, providing even more flexibility and cost optimization.
With Spot Priority Mix, customers can specify a base number of standard virtual machines and a percentage split of spot and standard virtual machines to be used when the scale set capacity is above the base number of standard virtual machines. This allows customers to ensure that their critical workloads are always running on standard virtual machines, while taking advantage of the cost savings offered by spot virtual machines for non-critical, interruptible workloads.
To get started with Spot Priority Mix, customers can use the Azure Portal, Azure CLI, Azure PowerShell, or ARM templates. For more information on how to set up Spot Priority Mix, please refer to the Azure documentation.
