Demystifying Technology: Virtualization Beyond Servers
Reviewed and updated in October 2026.
Virtualization has been used for decades to run servers as virtual machines (VMs) and deliver email, databases and other services to employees. It started with servers, moved to the desktop and more recently to mobile devices, with one goal: a secure digital workspace that users can reach from anywhere, on any device, regardless of who owns it.
Introduction
A virtual server does the same job as a hardware server, with advantages such as faster provisioning and deployment, lower hardware costs, better distribution of resources, portability and easier migration.
As most organizations move partly or fully to the cloud, virtualization has become another cloud service, which makes it even easier to deploy. Here are the options.
What is Virtual Desktop Infrastructure (VDI)?
VDI uses virtual machines to provide and manage virtual desktops for end users. Desktop environments are usually based on Windows or Linux. They can be hardened for security, branded with the corporate look and feel, and provisioned with the public or in-house apps users need for their daily work. These customized environments are called images, and an organization can build as many as its use cases require, for home office users, travelers or external collaborators, for example.
The VMs run on central servers, either on premises or in the cloud. A cloud offering is called Desktop-as-a-Service (DaaS); Microsoft's Windows 365 and Azure Virtual Desktop are well-known examples. VMs are delivered to users on demand, almost instantly.
Users reach their virtual desktop from their computer or mobile device through a web browser or a client app. After signing in with their corporate credentials, they land in their digital workspace and work with their usual business apps and documents, much as if they were sitting at an office PC. Resource-intensive applications run on server hardware rather than on the local device, and shared hardware can be assigned dynamically to VMs that need it, which makes better use of capacity overall.
Applications and data persist, so users can switch devices, from a tablet to a computer for example, without losing their work. Corporate data stays in the data center; only an encrypted display stream travels to the device, using a protocol specific to each vendor.
If something goes wrong, user data or the whole machine can be restored to an earlier state from regular snapshots.
What is Virtual Mobile Infrastructure (VMI)?
Like VDI, VMI hosts mobile apps centrally and gives users personalized, secure access to them from any device, anywhere.
Employees install a client app on their mobile device, sign in with their corporate credentials and reach a virtual workspace with their work apps and documents. The experience resembles an Android Enterprise or Samsung Knox device in Corporate-Owned, Personally Enabled (COPE) mode, with a private, unmanaged space and a managed work space. The difference is that the device itself does not need to be managed, which makes VMI a good fit for Bring Your Own Device (BYOD). How those management modes work is explained in Demystifying Apple, Android Enterprise and Samsung Knox.
The client app works as a secure container: data loss prevention rules stop information from leaving or entering it (see Demystifying Security: Data Loss Protection (DLP)). As with VDI, no corporate data is stored on the device; it only receives an encrypted pixel stream over a vendor-specific protocol.
Android is the usual operating system for mobile VMs, which is why VMI is sometimes called Android-based VDI. For organizations with in-house mobile apps, that simplifies development: an app built once for Android can be used from any mobile device without extra coding.
For BYOD, where little or no device management takes place, VMI lets employees use work apps and data securely while personal and corporate data stay completely separate. The organization has no access to or visibility of private data on the device. One example is described in Solution Highlight: Hypori Virtual Mobility.
Why virtualization?
Virtualization can give every employee a high-end experience while saving hardware costs, either through lighter, cheaper company workstations or by letting employees use personal devices in a BYOD program.
Security improves too. Corporate apps and data stay behind well-guarded walls, on premises or with a cloud partner, and only display data and input travel back and forth. That is containerization in its essence, and it fits well with a Zero Trust approach (see Demystifying Security: Zero Trust).
Employees can reach their digital workspace, apps and documents from anywhere, at any time, on any supported device. Which ownership model fits your organization is discussed in Why Ownership Model Matters.
IT teams benefit from simpler, more flexible resource management: a new, fully configured workspace with all corporate apps can be provisioned in minutes, adjusted when needs change and removed when an employee leaves.
Conclusion
Virtualization gives users a secure digital workspace they can reach from anywhere with a consistent experience. Whether VDI, DaaS or VMI fits best depends on your use cases, your devices and your ownership model.
