Virtual Desktop Infrastructure (VDI): Centralized, Virtualized Workspaces at Scale1 2VDI Overview:
VDI is a method of providing centrally managed virtualized workspaces to client devices at scale. Learn what VDI is, the competitive advantages of a VDI solution, and how you can support your remote access strategy with VDI.

Learn what VDI is, the competitive advantages of a VDI solution, and how you can support your remote access strategy with VDI. What Is Virtual Desktop Infrastructure (VDI)?VDI refers to abstracting and hosting numerous virtualized desktop sessions on a centralized, back-end server. These virtual desktops are then made accessible to users through thin client endpoints. (Thin client devices are typically cost-efficient PCs with minimal hardware, designed for one task or a few functions.) VDI has been around for over a decade and is a common method of providing a high number of repeatable endpoint experiences to a large workforce. Global disruptions such as COVID-19 mean that businesses need to be ready to support a massive remote workforce at short notice, and many IT decision-makers are looking with renewed interest at VDI as a potential solution to abstract the entire desktop or a subset of its applications. How Does VDI Work?In a VDI configuration, a central server hosts the entirety of the virtual desktop, including OS and apps. The server uses
remote procedure call (RPC), a series of functions that facilitate communication to and from end clients. System administrators use an RPC orchestrator on the server to configure the virtualized desktop environments, select which apps are available, and establish settings and permissions for the operating system (OS). End users will then individually connect to the server and access a virtualized desktop environment through their client PC. Usually, the endpoints in a VDI configuration will be
thin clients, which are PCs with an ultralightweight configuration: just enough processor speed and RAM to perform a few functions, built for a closed corporate LAN network. However, as the VDI model is evolving, new configurations are exploring the potential for supporting VDI over the cloud to PCs and rich end clients outside the corporate firewall. A key example of this is Windows Virtual Desktop, which Microsoft supports through the Azure cloud service. Windows Virtual Desktop
provides a full Windows 10 experience with Microsoft 365 apps, enabling more variety in productivity or interactivity compared to traditional VDI with stationary thin clients. Accordingly, the end user device for a Windows Virtual Desktop setup may offer a full PC or laptop experience with more-robust specifications, including a faster processor, Wi-Fi, and integrated graphics. Microsoft also hosts the infrastructure for
Windows Virtual Desktop, so businesses don’t need to invest in or manage server infrastructure to support the solution. Businesses can be up and running faster, and they spend less on maintenance and overhead.
Persistent and Nonpersistent VDIThere are categories of VDI deployments known as “persistent deployments” and “nonpersistent deployments.” Persistent VDI refers to VDI configurations that preserve end user settings and files each time the user logs out or shuts down their PC. Nonpersistent VDI locks down the virtual desktop such that any changes introduced by the end user are discarded at the end of each session. Saved files are wiped clean, configuration settings are reverted to default, and any unintentional change like downloaded malware is erased. Nonpersistent VDI can be used in an environment where endpoint PCs and terminals are publicly shared and there is no need to preserve user profiles from one login instance to the next. VDI vs. Desktop VirtualizationDesktop virtualization is a method that allows workers to remotely access and run applications on a desktop workspace from a separate device. A common scenario is when a worker logs into their office PC from their home PC using remote access software. Desktop virtualization may also refer to running multiple virtual machines (VMs) on a single device in order to keep workloads separate and isolated. A common example of desktop virtualization is when a worker runs two separate VMs on their PC: one VM for professional and business use and one VM for personal use. VDI is different from desktop virtualization in that desktop virtualization is decentralized. It generally refers to accessing or managing VMs between one or more devices. VDI is a centrally managed, locked-down environment where all virtual desktops are hosted on a back-end server. VDI Use CasesVDI can be useful to any industry that is looking to implement a highly repeatable end user experience at scale. Here are a few key examples:
Benefits of VDIVDI is useful in any scenario where an organization needs to lock down company data or limit end user functions to a singular purpose or mode of productivity. The following is a list of benefits in a traditional VDI use case, but as previously stated, the model is evolving to accommodate richer remote online experiences.
VDI Technology RequirementsTraditional VDI implementations are composed of one or more central servers and a number of lightweight endpoint devices. However, as workloads and multitasking are increasing in volume and scope, endpoints need to become more robust and offer richer end user experiences. The challenge with deploying rich clients in a VDI environment is that the more capabilities you add to an endpoint device, the harder it is to manage centrally and the more expensive it gets. This is especially true when you take endpoint devices outside the corporate firewall. As more and more businesses are turning to VDI and solutions like Windows Virtual Desktop to equip and enable their remote workforces, there is a greater need for remote manageability platforms to make it easier to access and secure these devices. Intel vPro® Enterprise for Windows OSRich clients enabled by Intel vPro® Enterprise for Windows OS are an ideal solution when paired with centralized, virtual desktop offerings like Windows Virtual Desktop to support agile and flexible remote workforces. This platform was purpose-built for business environments and equips IT departments with specialized tools to help secure and manage endpoint devices while helping to boost day-to-day productivity.
