Unlocking the Potential for Virtual Desktop Infrastructure

Virtual desktop infrastructure isnt new; companies have been creating and deploying virtual desktops for decades. VDI typically leverages local stacks to deliver performance thats nearly identical to user experiences during in-person access.

The process is fairly straightforward: IT teams designate a data center server for VDI, install virtualization software and then create virtual machines that effectively mimic local desktops. The result? Students logging in to local VDIs are greeted by the same desktop setup as on-campus alternatives.

Control is the biggest selling point for VDI solutions. Since virtual instances are spun up and managed on local stacks, university IT staffs enjoy granular control over security, resource access and digital sprawl. In addition, many schools have already deployed VDI solutions to reduce hardware footprints across physical classrooms. This serves an increasingly mobile student population, which in turn offers a ready-made starting point for more extensive VDI implementations.

By leveraging the as a service trend popularized by evolving cloud environments, DaaS solutions make the best use of public and private cloud resources to manage desktop instances at a distance. As noted by TechRepublic, the DaaS model has all hardware handled by cloud providers. This means local IT teams wont need to worry about maintenance, upgrading or compatibility issues.

Joyner puts it simply: A true DaaS solution is one where youre going to purchase a virtual desktop from a provider. Many will have canned offerings, such as Windows 10 instances that allot specific GPU and CPU resources.

While this means the configuration of specific apps and services still falls on in-house IT pros, the biggest benefit that DaaS brings is flexibility: New desktops can be created and customized on demand.

No matter which approach schools select, Joyner notes, user experience is king. Students expect services and resources to work as they do on campus. If you experience an unexpected lag, latency or lack a key functionality, this will frustrate users and limit the efficacy of online learning tools.

But VDIs and DaaS solutions offer so much more than easy interactions and straightforward access.

For example, virtual desktops excel at converting unused physical resources such as powerful PCs sitting untouched in computer science labs into easily accessible desktop instances. This is ideal for students who need to access GPU-intensive applications such as AutoCAD, even if they cant attend classes in person.

Meanwhile, DaaS offers the ideal solution for scalability. Since these desktop instances are cloud-based, they can be spun up or scaled down on demand, allowing schools to respond easily if enrollment rises quickly or suddenly levels off.

Both also come with potential pain points, however. According to Joyner, VDI solutions require more in-house expertise compared to the cloud, especially if schools choose to host these virtual instances entirely on-premises.

When considering cost, however, initial DaaS outlay often seems much more budget friendly. But as instances expand and usage increases over time, the price of offsite performance can outpace on-premises alternatives.

Its also worth noting that this isnt an either-or proposition. As noted by Joyner, schools can mix physical and virtual resources if they need scalability but also security. Theres no need to toss one or the other away.

The shift to learning at a distance wont disappear, even as pandemic pressures ease and students slowly return to physical classrooms. Its therefore critical that postsecondary schools find a desktop delivery framework whether its VDI, DaaS or a combination of both that empowers student success with familiar UX functionality, secure access to key systems and effective application of existing IT resources.
