PowerShell is a cross-platform task automation solution allowing scripting in Microsoft’s .NET framework. For Azure Virtual Desktop operations, AzureRm PowerShell module, which allows you to manage Azure resources, is highly useful.
Specifically, to create a new host pool, you can use the New-AzWvdHostPool command. Below is an example:
New-AzWvdHostPool -ResourceGroupName “resource-group-name” -Name “host-pool-name” -Location “location” -HostPoolType “Pooled”
This code automatically creates a new host pool in the specified Azure resource group.
Automating Host and Host Pool Creation with Azure CLI
Azure CLI is a command-line tool providing a great way to manage Azure resources. With the az desktopvirtualization command, you can create and manage Azure Virtual Desktop resources.
Below code demonstrates how to create a host pool using Azure CLI:
az desktopvirtualization hostpool create –resource-group “resource-group-name” –name “host-pool-name” –location “location” –host-pool-type “Pooled”
The above statement creates a host pool within the indicated resource group.
Automating Host and Host Pool Creation with ARM templates
ARM templates are JSON files defining the resources needed to run an application. By using ARM templates, you can define Azure resources in a declarative format.
To create a host pool via ARM template, you first need to create the JSON file. A simple template for creating a host pool may look like this:
{
“$schema”: “https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#”,
“contentVersion”: “1.0.0.0”,
“parameters”: { /*…*/ },
“variables”: { /*…*/ },
“resources”: [
{
“type”: “Microsoft.DesktopVirtualization/hostpools”,
“apiVersion”: “2020-10-19-preview”,
“name”: “[parameters(‘hostpoolName’)]”,
“location”: “[parameters(‘location’)]”,
“properties”: { /*…*/ }
}
],
“outputs”: { /*…*/ }
}
You would then input this file into the Azure portal or use Azure CLI/PowerShell to create this resource.
Automating Host and Host Pool Creation with Bicep
Bicep is a new Domain Specific Language (DSL) for deploying Azure resources declaratively.
A Bicep file to create a host pool would look something like this:
resource hostPool ‘Microsoft.DesktopVirtualization/hostPools@2020-10-19-preview’ = {
name: ‘hostpool-name’
location: ‘location’
properties: { /*…*/ }
}
You can then compile your Bicep file to an ARM template using the Bicep CLI.
Conclusion
Each of the above-mentioned tools – PowerShell, Azure CLI, ARM templates, and Bicep – are powerful in their own accord and provide valuable approaches for automating the creation of Azure Virtual Desktop hosts and host pools. These can be invaluable for those preparing for the AZ-140 Configuring and Operating Microsoft Azure Virtual Desktop exam, as well as for IT pros and SysAdmins managing cloud infrastructures. By knowing and understanding these methods, you can successfully automate your Azure Virtual Desktop operations and save both time and effort.
You might also want to consider that the choice of tool will depend on several factors including intricacy of the infrastructure, familiarity with the tool, and the specific requirements or restrictions of the project or business. Through practice and experience, you can become proficient in using these tools to automate and manage Azure resources effectively.

Interview Questions
What is the purpose of utilizing PowerShell in automating the creation of Azure Virtual Desktop hosts and host pools?
PowerShell is used to write scripts to automate complex and repetitive tasks in Azure Virtual Desktop. It allows you to create hosts and host pools in a programmatically and automated manner, thereby improving efficiency and reducing human error.
How does Azure CLI contribute to automating the deployment of Azure Virtual Desktop?
Azure CLI, which stands for Command Line Interface, helps in automating the deployment process of Azure Virtual Desktop by running a series of commands. It’s possible to write scripts using Azure CLI, which can then be scheduled or repeated as needed.
What is the role of Azure Resource Manager templates in the automated creation of Azure Virtual Desktop hosts and host pools?
Azure Resource Manager templates (also known as ARM templates) are JSON files defining the infrastructure and configuration of your Azure resources. These templates can be used to automate the deployment and configuration of Azure Virtual Desktop hosts and host pools, ensuring a consistent and repeatable deployment.
In the context of Azure Virtual desktop, What is Bicep?
Bicep is a declarative language for describing and deploying Azure resources. It simplifies the authoring of Azure Resource Manager (ARM) templates and brings additional features like type safety, modularity and better tooling support for developing and deploying infrastructure as code.
What is the key benefit of using automation in the creation of Azure Virtual Desktop hosts and host pools?
Automation helps in achieving consistent deployments, scaling operations, reducing the potential for human error, and most importantly, freeing up time from manual tasks to focus on value-added activities.
How does PowerShell differ from Azure CLI when used for the automation of Azure Virtual Desktop creation?
PowerShell is a scripting language with a wide range of functionalities applicable to various Microsoft products, while Azure CLI is specifically designed for managing Azure services. Both can be used to automate Azure Virtual Desktop creation, but the decision often boils down to the user’s preference and the specific use case.
What are some tools or services that can execute the ARM templates or the Bicep files?
ARM templates and Bicep files can be executed using various tools or services such as Azure CLI, Azure PowerShell, Azure Portal, or Azure Resource Manager (ARM) REST API.
Can Bicep replace ARM templates in automating Azure Virtual Desktop?
Yes, Bicep can be used as a replacement for ARM templates. In fact, Bicep compiles down to ARM templates, while providing a cleaner, simpler syntax and better tooling support.
What is the command to create a new Azure Virtual Desktop host pool using Azure CLI?
The command to create a host pool using Azure CLI is ‘az desktopvirtualization hostpool create’.
Can you automate the creation of both Personal and Pooled host pool types in Azure Virtual Desktop?
Yes, automation can be employed for creating both Personal and Pooled host pool types in Azure Virtual Desktop. Using PowerShell, Azure CLI, Azure Resource Manager templates or Bicep, you can define the type of host pool you want to create along with other configuration settings.
How does automating the creation process impact the management of Azure Virtual Desktop?
Automation can greatly simplify the management process by enabling mass deployment, configuration, and management of Azure Virtual Desktop hosts and host pools. Automation also allows for scalability and consistency in deployments.
What happens when a Bicep file is deployed in Azure?
When a Bicep file is deployed, it’s compiled into a JSON-formatted ARM template which is then executed. This ensures the defined resources are created and configured in Azure as per the declarations in the Bicep file.
How does automating Azure Virtual Desktop creation with ARM templates or Bicep contribute to Infrastructure as Code (IaC) practices?
ARM templates and Bicep files define the desired infrastructure state in a declarative way, which is fundamental to Infrastructure as Code (IaC) practices. With IaC, the infrastructure to host applications becomes reusable, maintainable, extensible, and easy to manage, which is an advantage for deploying Azure Virtual desktops at a wider scale.
Are there built-in templates available for automating Azure Virtual Desktop deployment?
Yes, Microsoft provides some built-in templates to deploy Azure Virtual Desktop and related resources. These templates can be customized as per the specific deployment needs.
Can we use both ARM templates and Bicep together for automating Azure Virtual Desktop deployments?
No, Bicep serves as an alternative to ARM templates, designed for overcoming some limitations of ARM templates. However, Bicep files are transpiled into ARM Template JSON files, you should choose either ARM or Bicep based on your specific requirements and preference.
