 When creating or updating a Batch pool, you specify a [configuration](nodes-and-pools.md#configurations). Pools should generally be configured with Virtual Machine Configuration, which lets you either specify one of the supported Linux or Windows VM images listed in the [Azure Virtual Machines Marketplace](https://azuremarketplace.microsoft.com/marketplace/apps/category/compute?filters=virtual-machine-images&page=1), or provide a custom image that you have prepared. Cloud Services Configuration pools provide only Windows compute nodes and do not support all Batch features.
 
-When you run **New-AzBatchPool**, pass the operating system settings in a PSVirtualMachineConfiguration or PSCloudServiceConfiguration object. For example, the following snippet creates a Batch pool with size Standard_A1 compute nodes in the virtual machine configuration, imaged with Ubuntu Server 18.04-LTS. Here, the **VirtualMachineConfiguration** parameter specifies the *$configuration* variable as the PSVirtualMachineConfiguration object. The **BatchContext** parameter specifies a previously defined variable *$context* as the BatchAccountContext object.
