What is virtual desktop infrastructure (VDI)? - Definition from WhatIs.com. Virtual desktop infrastructure (VDI) is the practice of hosting a desktop operating system within a virtual machine (VM) running on a centralized server.
Fusion PPT compared the leading vendors and their offerings. In spite of its many perceived benefits, virtual desktop infrastructure (VDI) has yet to fully gain traction and still remains a niche market. After well over a decade since its early introduction, VDI has faced challenges when it comes to truly duplicating the local desktop and competing on cost. The introduction of cloud-based computing models for VDI (known as desktop as a service or DaaS) now offers a combined benefit and challenge to the IT decision maker. Whereas on-premise data center-hosted VDI represented a known model that has been tested and refined over the years, cloud-based VDI is the new kid on the block and has yet to effectively prove itself. In this guide, we take look at four of the leading VDI vendors, including their capabilities and differentiators. VDI shoot-out: Citrix XenDesktop vs. VMware View. More than 20 years ago, the desktop revolution swept across the land, ushering in a new paradigm of computing, taking processing away from a centralized host, and moving it to personal computers at the edge of the network.
With VDI (virtual desktop infrastructure), as the saying goes, what's old is new again. Using virtualization, IT now has the ability to bring those distinct computing platforms back under one roof, while also providing for greater control and flexibility of user access. This review of VDI solutions features the two heaviest of virtualization heavyweights. As in my comparison of entry-level VDI solutions (Kaviza VDI-in-a-box, NComputing vSpace, and Pano Logic's Pano Express), my goal was to see what it would take to deploy a complete VDI solution based on Citrix XenDesktop 5.5 and VMware View 5 for up to 50 users. During my evaluation, I found that conceptualizing the deployment was easy.

What ever happened to VDI? It's a good question: What ever happened to VDI?
It's a question that I think some of us have forgotten to ask over the past six or seven years. I remember a time when predictions were in the billions of dollars related to converting standard desktops to virtual ones via VMware, Citrix, and others. Funny thing is it hasn't really happened. I wrote on ZDNet, in Linux Magazine, and other places as well that VDI is too expensive, doesn't perform well, users hate it, and it's a transitional technology. My last assertion that VDI is a transitional technology is really the focus of this post. Do you really need VDI? Try desktop as a service instead. For years, IT has been looking at virtual desktop infrastructure (VDI) as a more managed, consistent way to provide Windows desktops to users via local PCs or thin clients.
Vendors have provided a variety of tools to alleviate the LAN and storage bottlenecks that VDI can create as all those PC sessions travel over the local network to the hosting servers in the data center. Vendors have even WAN access to VDI, so it only makes sense that eventually the idea of using VDI through a cloud service provider would arrive. It has, in the form of desktop as a service (DaaS). DaaS provides IT the same advantages as local-network VDI -- centralized desktop control and security, centralized data control and security, and centralized backup and disaster recovery for those virtual PCs -- but also eliminates all the capital expense of an on-premises VDI deployment.
Rather than buy all that equipment, you essentially rent it from the cloud provider as part of your subscription cost.
