 ## Scale set deployment  
 The process to create a scale set that uses an ephemeral OS disk is to add the `diffDiskSettings` property to the 
 `Microsoft.Compute/virtualMachineScaleSets/virtualMachineProfile` resource type in the template. Also, the caching policy must be set to `ReadOnly` for the ephemeral OS disk.
