How to get list of virtual machine sizes which supports spot instace ?

Question

Hi all,

I am trying to get a list of virtual machine sizes which supports Azure spot instances in a given location.

I have tried below API :

GET https://management.azure.com/subscriptions/{subscription-id}/providers/Microsoft.Compute/locations/._../vmSizes?api-version=2023-03-01

result of the above API was :

 {
      "name": "Standard_B1ls",
      "numberOfCores": 1,
      "osDiskSizeInMB": 1047552,
      "resourceDiskSizeInMB": 4096,
      "memoryInMB": 512,
      "maxDataDiskCount": 2
    }

I cannot see a tag for the spot instance in the above response. Can you please help me with this?

Answer 1

Hi, Prajyot

Check out Azure Price - https://azureprice.net/?tier=spot

You can adjust the VM sizes to include spot compatible VMs.

Answer 2

You can run below Resource Graph Query
Below query extract all D services VMs supporting SPOT for European region.

SpotResources 
| where type =~ 'microsoft.compute/skuspotpricehistory/ostype/location' 
| where sku.name matches regex @'(?i)Standard+_(?i)D[0-9]+_v[0-9]'
| where properties.osType in~ ('linux','windows')
| where location in~ ('westeurope', 'norteurope') 
| project skuName = tostring(sku.name), osType = tostring(properties.osType), location, latestSpotPriceUSD = todouble(properties.spotPrices[0].priceUSD)
| order by latestSpotPriceUSD asc
