Step-by-Step Guide to Windows Virtual Desktop Fall 2019 Release

Create a Host Pool
Part 1 of this series gave an overview of Windows Virtual Desktop. Part 2 was about creating a WVD tenant. Part 3 created a service principal, and assigned a role to the service principal. You will now use the Azure Marketplace for provisioning a host pool. Hosts are the virtual machines that users connect with in your WVD tenant.

Provision of a new host pool
Sign in to Azure Portal. Next, use the search bar at top to type Windows Virtual Desktop. Make sure you select Windows Virtual Desktop – Provision a hostpool from Marketplace Windows Virtual Desktop under Services is used in conjunction with the Windows Virtual Desktop Spring 2020 Update, which I will discuss in future posts.

This will take to you to a overview of Windows Virtual Desktop. Click Create to start provisioning your host pool.

The pages or tabs in the host pool provisioning wizard are organized into pages. There are four tabs: Basics; Configure virtual machines; Virtual machine settings; Windows Virtual Desktop information.
Basics
The Basics tab:
1. Subscribe
Select your subscription from this list.
2. Resource group
Choose an existing resource group or choose Create new and give it a unique name.
If you want to select an existing resource type but it isn’t in the list, then you might need to change your region in the next field and then select the resource again.
3. Region
Select a region from this dropdown list.
4. Name of the host pool
Enter a name to be your host pool. This name must be unique.
5. Type of desktop
If you choose Personal, each user will be assigned a virtual machine permanently.
You can select Pooled to get Windows 10 multi-session and multiple users per VM.
6. Default desktop users
You will need to enter a list of UPNs for the users that you wish to grant access to Windows Virtual Desktop.
You will add the users to the Desktop Application Group and get full Windows 10 desktop access.
PowerShell allows you to add users later. I like to add one user here for testing and then add more users later.
Add at least one licensed user to your deployment to ensure that you can test it at the end. Remember the Part 1 license requirements?
7. Service metadata location
You can choose the same location that you used for the virtual network with connectivity to your Active Directory domain controller.
8. Next: Configure virtual machines

Configure virtual machines
On the Configure virtual machine tab:
Create an Availability List
Availability sets ensure that VMs are distributed across multiple hardware nodes in a cluster. This provides high availability.
Profil de usage
The usage profile determines how many users are per vCPU. There are three options: Light (6), Medium ((4)), Heavy (2), and Custom. To create a certain number of VMs, choose custom.
Total users
You will create 3 VMs in the host pool if you choose Light (6) and enter 50 users. Each VM can support 6 users and has 4 vCPUs. That’s 24 users per virtual machine. Two VMs could cover 48 users. You’ll need three VMs to support 50 users.
Size of virtual machine
You will see the number and default size of the VMs created based on your selections.
Prefix for virtual machine name
Name VMs by adding a dash to the prefix that you specify and an incrementing number. (Prefix-1, Prefix-2,…)

6. Select Next: Settings for virtual machines
Setting up virtual machines
You will find the following information under the Virtual machine settings tab
Image source
You can choose from Blob storage, Managed images, or Gallery. You can choose to have Blob storage, Managed image, or Gallery.

Disk type
You can choose between Standard SSD, Premium SSD, or Standard HDD.
AD domain join UPN
Enter the UPN password and username of an account that has permissions for joining the VMs to yourdomain.
