Back to Tech

When I started working as a technical director for AppSense at the beginning of 2011, the deal was that I can use a good part of my working time for contributing to the RDS/VDI expert community in a vendor-independent manner. What this means is that AppSense is paying me for doing stuff that is not necessarily related to only AppSense products, like looking into the technology behind Microsoft desktop virtualization, Citrix XenApp/XenDesktop or VMware VDI. But when our new Area Vice President Central Europe Stefan Hoelzl joined AppSense last April, we agreed on a temporary change of my job description. My new role was focused on building a strong technical team in Stefan’s territory as fast as possible. But he also said that he wants me to do this only for a limited time span and then return to my initial role.

So for the last nine months I was absorbed by restructuring and growing the AppSense professional services and presales team in Central Europe. As you can imagine, managing a fast growing number of technology experts didn’t leave me as much time as I sometimes wished for digging into technologies outside the scope of AppSense. But I can tell you that I had a great time doing this job, working with some great techies on my team.

In December we hired Georg Theunissen as our new director heading this technical team in Central Europe. Now, after the transition from me to him as the team lead, I’m back to what I like most: Digging into virtualization technologies and evangelizing other experts. As a technical director and a member of the global office of CTO at AppSense it’s one of my primary objectives looking at hot virtualization products. This means that I can spend more time digging into virtual desktops and remoting protocols again – and share my findings and opinions with the community.

New Tutorials

A couple of days ago I created a new section on my website, called Tutorials. I want to use this section as a library for documents I create when testing new RDS or virtualization functionalities or when preparing for delivering presentations or training classes. I started uploading a couple of documents I have already created in the past. Check them out and tell me what you think.

At this moment, the topics I have in mind for the different tutorials are as follows:

Stay tuned for the things to come in my Tutorials section…

VDI in the Cloud at HP Discover 2011

A couple of days ago I had the opportunity to attend HP Discover 2011 in Vienna. AppSense was one of the exhibitors there and I presented our sponsor session at day 1. It was my first time at Discover and I must say that I was impressed: 7,000 attendees, 270 executive meetings and 533 track sessions combined with a big exhibition hall full of HP technology and partners from HP’s eco system.

Besides evangelizing attendees and HP staff about the value of AppSense User Virtualization, I spent some time trying to find out what HP’s story is around desktop remoting and desktop virtualization in combination with their cloud offerings. Read more..

How to Compare Remoting Protocols

If you want to learn about a good way of comparing remoting protocols such as Microsoft RDP/RemoteFX, Citrix ICA/HDX, VMware/Teradici PCoIP and Quest EOP, this article is for you. As you may already know, Shawn Bass and I have invested substantial time into testing and comparing the most popular Windows remoting protocols in our vendor-independent labs over the last months and years. Presenting our results at major industry events such as Microsoft Tech-Ed, Citrix Synergy, VMware VMworld and BriForum created some buzz in the market. Occasionally, vendors like Citrix and Teradici made some controversial public comments about our findings and conclusions. Read more..

Citrix Synergy Europe 2011 – Impressive and Confusing

I’ve been in Barcelona last week, attending Citrix Synergy. If I were a Citrix customer, I’d be both impressed and confused after this event. There is a simple reason for this: While Citrix introduced amazing new products and announced spectacular acquisitions, they missed to present a clear strategy or just a simple overview. What is a customer supposed to do now? Stay with the products he already bought and just upgrade them? Move everything into the cloud? Collect information about all the new Citrix components and products in order to build the big overview picture themselves?

Let’s dig into the details and take a look at the things Mark Templeton and a handful of live demo specialists covered in a two and a half hour keynote on Wednesday morning. Read more..

New Website Design

It’s done. My website goes from the old wtstek.com design that seems to come from the 80′s of the last century to a modern theme. Graphics design and usability improvements are from Katie Lancaster, Mangoberry Web Design and Services. Many thanks, Katie! Read more..

RemoteApp on Windows 7

Many people know RemoteApp programs as applications that are accessed remotely through Remote Desktop Services on Windows Server 2008 (R2). RemoteApp programs appear as if they are running seamlessly on the end user’s local computer. Not many people know that RemoteApp programs are also configurable on Windows 7. Read more..

Lie to me – Using Built-in Windows System Filters

I bit more than a week ago, I presented a brand new technical session at BriForum in Chicago.  It had the title “Lie to me – Using built-in Windows system filters in virtual desktops”.  In this article I want to give you a brief overview of what I shared with the BriForum attendees. Read more..

Building a Hyper-V Client Hypervisor – Part 2

A couple of weeks ago I published an article describing my experiment to use Hyper-V as a client hypervisor. I’m working with this laptop setup since more than two months now, using it for everything I previously did on Windows 7. In addition I’m running all my demos when visiting customers or presenting at conferences. Now I want to share some lessons learned. Read more..

Spring 2011 Conference Season

It’s conferences season again, and I love it. Shawn Bass and I invested a couple of weeks into some fun stuff, like building reference environments in our labs, collecting new data and recording 400 videos for the new version of our remoting protocol comparison. Then we co-presented the results at BriForum in London (May 10 to 11) and at Microsoft Tech-Ed in Atlanta (May 16 to 19). Shawn presented it at Citrix Synergy in San Francisco (May 25 to 27) and I was invited to present it at Citrix Technology Exchange in Munich (June 6 to 7). Wow, this is just awesome – wait, it is “splendid”, I’m now working for a company that was founded in the UK. Read more..
