Presentation Virtualization

Presentation Virtualization is an application delivery method that delivers users desktops and applications from a shared server, AKA server based computing. This method of delivering applications to users focuses upon running an instance of each Windows desktop operating system application i.e., Word, Excel, PowerPoint and Office for each user on a shared instance of a Windows Server operating system. (Read More)

The most popular product in this category is Citrix XenApp and its predecessors which include Citrix Presentation Server, and Citrix MetaFrame. In the 6.0 releases of its products, Citrix bundled XenApp into XenDesktop. In the 7.0 releases of its products, XenApp has been made available separately again. Microsoft also has a product in this category – Microsoft Remote Desktop Services, but this offering is mostly used in smaller implementations that do not require the enterprise class features that Citrix offers.

UIAs: Whatever Happened to Them?

ApplicationVirtualizationA couple of years ago, UIAs (user-installed applications) were all the rage. AppSense had a product called StrataApps (and you can do it in Application Manager also), RES has native functionality that allows this, Unidesk can do it (admittedly in a slightly different way with its layering technology), Citrix was pushing Personal vDisk with its acquisition of RingCube—the list goes on. However, the actual use of UIA functionality has been limited, to say the least, and the response to it from IT departments remains frosty at best. Despite predictions that UIA requirements would become an integral part of desktop and (to a lesser extent) server virtualization projects, they seem to have quietly faded away. What happened to the UIAs?  Continue reading UIAs: Whatever Happened to Them?

Coopetition: Citrix +/- VMware Products and People

DesktopVirtualizationIconIn the virtualization marketplace, when a vendor expands its core business and attempts to grab a piece of the new market from an existing incumbent, the vendors view each other as competitors. In 2007, when Citrix purchased XenSource, VMware vSphere clearly became the enemy, and Citrix envisioned that XenServer + XenApp/XenDesktop would take over the virtual world. That didn’t quite happen. Continue reading Coopetition: Citrix +/- VMware Products and People

Citrix Solved the vGPU Problem, So…Where Is the Parade?

DesktopVirtualizationIn March 2013, Citrix announced they had GPU sharing working and available for XenApp (multi-user/RDS). In December 2013, they announced it was available for XenDesktop (multi-OS/VDI). This has been a major barrier to adoption for many companies that need the ability to deliver a high-end multimedia experience to their end users in order to gain acceptance for adoption.

Installing/Packaging Applications: The Unexpected Bottleneck

ApplicationVirtualizationVirtualizing applications is simple, right? After all, Microsoft Office can be installed or packaged in a matter of minutes, so all apps must be this easy. And via a tool like Citrix App Orchestration, the application can be published, secured, and presented to users auto“magic”ally. Thus, application virtualization professionals must have easy jobs, right?  Continue reading Installing/Packaging Applications: The Unexpected Bottleneck
