Windows 10 Virtual Desktop is a desktop and app virtualization service that runs on the cloud." The cloud Microsoft is talking about is Azure, and running WVD on Azure gives the following benefits:
A scalable multi-session Windows 10 (full) deployment
Virtualization of Microsoft 365 Apps for enterprise
Windows 7 Virtual Desktops with free Extended Security Updates (for enterprises that haven't migrated to Windows 10)
Bring your existing Remote Desktop Services (RDS) and Windows Server desktops and apps to any computer
Virtualization of both desktops and apps
Ability to manage Windows 10, Windows Server, and Windows 7 desktops and apps with a unified management experience.
One of the main benefits of WVD is that a user can access their desktop from anywhere they have internet access, using their company-issued device, a shared work computer, or their own device. So an employee who finds themselves stuck in a remote location would be able to dial in and have their same desktop experience with all its functionality and personalization.
By using WVD, an enterprise can realize cost savings in several ways. First, hosting on Azure greatly reduces the infrastructure needed, mainly servers and the rooms to house them in. Also, with employees being able to work from anywhere, the amount of office space needed is less, especially when options for shared work spaces, like WeWork and Regus, are available.
Labor savings will also be significant since you won't need as many full-time employees to maintain a vast infrastructure. Also, a part of labor savings will come from needing less help desk support staff. This is because desktops are created virtually with the latest versions, so there are no issues with installation or older versions.
For companies that will allow employees to bring their own device (BYOD), the budget for new devices can be reduced since those companies are relying on the employee.
Scalability and Security
A company that wants to grow quickly can do so with WVD. Massive rounds of hiring don't need to be hindered by new infrastructure setup or device procurement in a BYOD setting. For company-issued devices, the processes of creating an image, app packaging, and app deploying aren't necessary. Conversely, an organization that is going through a re-organization or layoffs can easily downsize the amount of users on WVD, and if it was a BYOD environment, it isn't stuck with devices and servers that will become outdated soon.
