+### Azure Resource Graph
+
+You can programmatically access relevant Spot VM SKU data through [Azure Resource Graph](/azure/governance/resource-graph/overview). Get pricing history in the last 90 days and eviction rates for the last 28 trailing days to identify SKUs that better meet your specific needs. 
+
+Key benefits: 
+- Query Spot eviction rates and the last few months of Spot prices programmatically through ARM or the [ARG Explorer in Azure portal](/azure/governance/resource-graph/first-query-portal)  
+- Create a custom query to extract the specific data relevant to your scenario with the ability to filter across a variety of parameters, such as SKU and region  
+- Easily compare data across multiple regions and SKUs  
+- Find a different Spot SKU or region with a lower price and/or eviction rate  
+
+Try out the following sample queries for Spot pricing history and eviction rates using the [ARG Explorer in Azure portal](/azure/governance/resource-graph/first-query-portal). Spot pricing history and eviction rates data are available in the `SpotResources` table. 
+
+**Spot pricing history sample query**:
+
+```sql
+SpotResources 
+| where type =~ 'microsoft.compute/skuspotpricehistory/ostype/location' 
+| where sku.name in~ ('standard_d2s_v4', 'standard_d4s_v4') 
+| where properties.osType =~ 'linux' 
+| where location in~ ('eastus', 'southcentralus') 
+| project skuName = tostring(sku.name), osType = tostring(properties.osType), location, latestSpotPriceUSD = todouble(properties.spotPrices[0].priceUSD) 
+| order by latestSpotPriceUSD asc 
+```
+
+**Spot eviction rates sample query**:
+
+```sql
+SpotResources 
+| where type =~ 'microsoft.compute/skuspotevictionrate/location' 
+| where sku.name in~ ('standard_d2s_v4', 'standard_d4s_v4')

+| project skuName = tostring(sku.name), location, spotEvictionRate = tostring(properties.evictionRate) 
+| order by skuName asc, location asc
+```
 
+Alternatively, try out the [ARG REST API](/rest/api/azure-resourcegraph/) to get the pricing history and eviction rate history data.
