Virtual desktop word bingo (XenDesktop 7)

XenDesktop 7In my previous article you’ve read about my aversion against the term VDI. The introduction of Citrix XenDesktop 7 showed us that delivery of  applications and desktops from shared and private computers are now integrated in one product. This requires us to explain the difference between shared versus private instead of XenApp versus XenDesktop, so now really is the time to start using new (and proper) terminology.

In the previous virtual desktop word bingo article I’ve asked you if you think we should abandon the term VDI, 61% agreed while 26% disagreed. The response showed that a lot of readers agree the term VDI is “incorrect” but replacing the term will be tough. Nonetheless I strongly believe we, as the community / experts, should strive to replace “VDI” with more future ready terminology.

Virtual desktop word bingo (stop using VDI)

I have developed a strong aversion against the term “VDI”. Basically because customers don’t understand what VDI means, caused by the simple fact that the people who explain this to the customers (the people in IT) don’t understand it either.

The term VDI is roughly 7 years old. Back then we presumed it was the right term to use, and maybe it was. But time has changed and I strongly believe we are ready for some change.

Are you ready for some virtual desktop word bingo?

You don’t need XenDesktop for a virtual desktop

Author: Ingmar Verheij

XenDesktop 7For years Citrix has a product to host applications from a centralized locations offering great flexibility and efficiency, called Citrix XenApp. In 2008 Citrix released XenDesktop, the VDI solution from Citrix. With this first release of XenDesktop it was possible to (only) publish a desktop hosted on a single user operating system (like Windows XP, Vista or 7).

Citrix has tried to choose an appropriate name for their products to help customers understand what product offers what solution (and reducing the ridiculous times they rename their products). Although this is an admirable attempt they failed to reach that goal.

A lot of customer assume that with XenApp they can (only) publish applications and with XenDesktop (only) desktops, how wrong can they be?

Whitepaper : Quantify Perceived Performance

Author: Ingmar Verheij

Determining the user experience is challenging since the experience is based on many factors. The performance of an application is one of the factors that determine the user experience.

If the performance of an application is bad, the user will grade the experience as bad.

Your machine(s) everywhere

Citrix Synergy starts tomorrow in San Francisco. From wednesday 12 may till friday 14 may all updates, new features and other news is presented to the public. One thing that’s excites me most is the upcoming XenClient, a baremetal hypervisor.

Combined with a VDI solution like XenDesktop the XenClients enables the customer to take the VM outside the datacenter en get it onto his desktop / laptop using his local resources. Altough this sounds a bit like we were used to work, and in fact it is, there is a big difference.

Do we need 'fancy' features for VDI?

Everyone knows that more and more people are thinking about VDI, or at least they’re talking about VDI. And most of these people don’t really know what they’re talking about, what they really want and what they need. There are more usecases, solutions, alternatives which might be better for most of them.
In this article i’m talking about ‘hosted virtual desktops’, the way most people see VDI. The desktop is a virtual machine running on a hypervisor in the datacenter.

Yesterday I attended a presentation where VMware was talking about VMware View, there product for VDI implementations. In this presentation one of the key-features of VMware View was there ESX plaform, and all the ‘fancy’ features this hypervisor has. And with ‘fancy’ features I mean features like VMotion, High Availability, DRS and Fault Tolerance.
These are all great features and very usefull, in enterprise environments, for servers. In smaller environments these features aren’t necessary or even needed. In fact, in most enterprise environments not all features are really required, there used because “we can”.
