What is Azure VDI and its advanatages?

VDI on Azure is the use of Azure resources and services to create an infrastructure for the remote delivery of desktops. It is based on Azure’s Windows Virtual Desktop (WVD) service, which you can manage with Remote Desktop Session Host. The service is designed to enable you to deliver Windows desktops to your users on nearly any client device.
Here are the top three benefits of the Azure VDI
1. Range of Potential Uses
The amount of use cases for WVD are endless. For example, virtual desktops can be provided to remote workers securely using your existing Active Directory for authentication, thus allowing users to access their desktop from home via the internet.
Do you have a legacy application that you want to publish to a subset of users? Applications can be installed on a WVD host and published to a group of users in order to minimize maintenance and management.
WVD is a global service from Azure. WVD hosts can be deployed in multiple regions around the world to support your users globally. Being able to provide virtual desktops within the same geographic regions of your remote users ensures a great user experience.

2. Ease of Management
The WVD service manages the RDS infrastructure, so you only need to manage your users, applications, and virtual machines. RDS components such as Gateways, Brokers, and Licenses are provided by the WVD service and no longer need management. If you already have Microsoft 365 licenses, it covers WVD licensing for Windows 10.
With the latest WVD release (Spring 2020), the WVD components are now Azure Resource Manager (ARM) resources and can be managed within the Azure portal or through PowerShell. This makes managing WVD much more convenient. For example, users can be assigned to personal desktops or pools of desktops within the portal and through Azure Active Directory (Azure AD) group memberships.

3. Windows 10 Multi-Session
WVD hosts can be Windows 10 Enterprise, Windows 7 Enterprise, Windows Server 2012R2, 2016, or 2019. However, a major benefit of WVD is the availability of the Windows 10 Enterprise Multi-Session Operating System.
This OS support allows for multiple users to log into a single Windows 10 VM. The multi-session capability promotes significant cost savings compared to other VDI solutions. In standard VDI solutions, single users are assigned a dedicated virtual machine. Whereas when using Windows 10 multi-session with WVD, multiple users are assigned to a pool of desktops, thus sharing resources (and costs).

I hope this information is helpful!
