Since launching XenDesktop, one of the most common questions I have heard from XenApp customers is "Why would I use XenDesktop with my current XenApp implementation?" Well, there are a lot of reasons and this white paper helps answer them. According to the document's description:

The white paper explores these areas:

• Best Practice: Separate Apps and Desktop
• Step 1: Is it an app or desktop problem?
• Step 2: Which workers have this problem?
• Step 3: Identify the solution
• Step 4: Justify with Cost Analysis

Take a read and let us know what you think.

 XenApp and XenDesktop: Using Application and Desktop Virtualization Together

Did you know that Citrix has a private Customer Advisory Community that enables global Citrix customers to serve as virtual advisors, providing their perspectives and opinions in an online forum?  The Customer Advisory Community is comprised of 400 Citrix customers who span more than 30 countries and represent a broad cross-section of industries and organizations.

Customer Advisory Community members log in to the site each week, and provide Citrix with a wide range of feedback, including insight into their organization's IT direction, IT industry trends, and feedback on Citrix products, services and marketing, among other topics.

The Customer Advisory Community has a limited number of openings for new members this month, and we would like to offer Citrix customers the opportunity to be considered for membership!   

As a member of the Citrix Customer Advisory Community, you would have the ability to:

• Provide insight into your organization's needs and challenges
• Share your thoughts on a variety of technology industry topics
• Learn early on about new Citrix initiatives and influence their direction
• Interact and network with your peers in a private, online forum
• Receive periodic rewards in exchange for your participation (if your organization's policies allow)

Those chosen to participate in the Citrix Customer Advisory Community will be asked to complete a click-through Non-Disclosure Agreement, create an account, and then log in and contribute their thoughts (via surveys, bulletin boards, etc.) an average of 5-15 minutes per week. Citrix partners with Communispace Corporation, a professional community management firm, to host and moderate the online advisory community.
 
To be considered for membership, please complete this brief, 10-minute questionnaire by July 25, 2008. Customers using one or more Citrix products are encouraged to apply.

We hope to see you in the community!

There have been nearly 10,000 runs of the (free) XenApp Upgrade Calculator, which launched in 1Q08. Customers and partners alike have found it valuable in making cost comparisons between applying a Subscription Advantage (SA) budget and upgrading editions of XenApp. Since the first year of SA is included in all XenApp edition upgrades, upgrading at SA renewal frequently makes financial sense.  Here is what a couple of partners have said about the current calculator:

• "I hear customers ask all of the time... "What would be the cost difference between upgrading my existing solution and just getting the latest?" Citrix made it happen again, nice tool!"
  (Citrix Platinum Partner)

• "Time Saver!! When the customer wants to know what the cost savings are compared to the upgrade, here is the tool for it. Way to go Citrix!"
  (Citrix Platinum Partner)

 The next version of the XenApp Upgrade Calculator is imminently available. Some of the new functionality includes:

• Country pricing
• Volume discounts
• Feedback
• Download of XenApp Evaluation Virtual Appliance

Stay tuned for the announcement on this blog and let us know what you think about either the current calculator or the next version.

One of the most common questions from the field, especially after Citrix acquired XenSource, was "What type of performance do I get if XenApp is virtualized on the server?". This Tolly Group Report conducts a performance evaluation of Citrix XenApp in a 64-bit virtualized server environment using Citrix XenServer Enterprise 4.1.0.  Test highlights include:

• Achieves maximum performance of users when XenApp runs on a 64-bit XenServer virtual machine, operating with as little as 7.6% overhead versus running XenApp in a comparable physical server environment
• Virtualized 64-bit XenApp exhibits 82% higher performance than a 32-bit virtualized environment using XenServer
• Provide features to allow XenApp to run at optimal performance levels with default configuration

If you're interested in running XenApp with XenServer, be sure to check-out these other white papers:

• Benefits of Virtualizing Citrix XenApp with Citrix XenServer
• Optimizing XenApp Performance with XenServer 4.1.0 Enterprise Edition

Learn how to run AutoCAD Map 3D on Citrix XenApp in this webinar on Wednesday, June 25, 2008 featuring Arnold Schwabe, Autodesk Technical Consultant.

A number of guides for running AutoCAD on Citrix environments have been floating around on the Web. There is the  unofficial guide to running AutoCAD 2006 via Terminal Services or XenApp (it was called Presentation Server at that time) as highlighted by Michel Roth.  More recently, Gus Pinto from Citrix highlighted the just-released guide Installing AutoCAD Map 3D on Citrix XenApp. In short, I've observed a lot of energy around the Citrix/Autodesk relationship in the past few quarters.

Now learn more about running AutoCAD Map 3D on XenApp by attending the Citrix and Autodesk TechTalk webinar (registration required) . Topics to be covered are: 

• Simplify application management by delivering AutoCAD Map3D with Citrix XenApp
• Improve efficiency and flexibility of Autodesk's geospatial applications
• Enhance application performance - scalability and performance test results
• Technical overview of installation and server configuration
• Reduce costs - a detailed look at ROI results

Featured Speaker
Arnold Schwabe, Autodesk Technical Consultant

Arnold has been using Autodesk products since 1990 in a variety of fields including agriculture, dredging, forestry, land development, property management, and geospatial consulting for government agencies and private companies. He has also spent time in IT/IS administrator roles in similar organizations. While working for an Autodesk reseller, he taught and authored several standard and custom training classes on AutoCAD, Land Desktop, Civil 3D, and Autodesk Map. As a consultant, he has provided services related to geospatial and civil products and worked as a contractor to Autodesk for Civil 3D QA work and testing of new functionality of Map 3D.

You can find more information on how Citrix and Autodesk are working together here.

Leave a comment on anything that you would like to cover during the webinar. I will pass it along to the presenters.

Want to understand the differences between Presentation Server 4.5 and Terminal Services in Windows Server 2008 and Windows Server 2003? Take a look at the new 14-page Citrix Presentation Server on Windows Terminal Services: A Feature Analysis  just completed by the Citrix Technical Marketing Team. But this is not just the Citrix perspective on what is different between the products. This document was co-developed with a couple of members from the Microsoft Terminal Services team (blog), so it is the view of Citrix *and* Microsoft on the products.

The analysis looks at these 5 areas:

• Centralized Control
• Application Compatibility
• Optimized User Experience
• Comprehensive Access
• Enterprise Scalability

By the way, If you combined download counts for earlier versions of the Presentation Server and Terminal Services side-by-side evaluation docs previously available on citrix.com, that combined count would rank as one of the top 5 most downloaded docs in the past 12 months... out of nearly 750 docs on the citrix.com site.
 
You can also see more Citrix coverage at the tag Windows Server 2008 on the Official Citrix Blog.

Take a read of the new feature analysis and let us know what you think by leaving a comment.

With the launch of Windows Server 2008 this past Wednesday, Feb. 27, 2008, the question "Do I need Citrix or is Terminal Services enough" is back en vogue. In fact, the Google search for "do i need citrix with windows server 2008" is one of the top 3 search phrases driving traffic to my blog.  In that search, my earlier post Evaluating Project Delaware and Terminal Services in Windows Server 2008 is the 6th-ranked result. Brian Madden's classic post, Do you need Citrix or is Terminal Server enough?, with 22,000+ views, is the top result. Clearly, people are interested in this topic. Today, Citrix took the next step to help customers understand the differences and released this new white paper:

Citrix XenApp on Microsoft Windows Terminal Services - A Feature Analysis

Compare the base-level features of Terminal Services within Microsoft® Windows Server® 2003 and Windows Server 2008 to the features of Citrix XenApp™ (the new name for Citrix Presentation Server) running on Windows Server 2003.

Take a read and let us know what you think. I expect this doc will be updated once Project Delaware is released.

UPDATE: The Feature Analysis on Windows Server 2008 has temporarily been removed as we make additional edits based on feedback (thanks!). The previous version is available here. Once the updates are completed, I will re-post the new version on this blog. I apologize for the inconvenience and understand the frustration this may cause.

Update 2: The new 14-page Citrix Presentation Server on Windows Terminal Services: A Feature Analysis is now available. Read more here.

In the spirit of the Oscar Awards last night where No Country For Old Men won best movie of the year ( a surprise to me), I thought I would pronounce the best Citrix "film" of the year. And the winner is... Understanding and Designing Presentation Server Farms (scroll down)

Of all the Citrix XenApp (the new name for Presentation Server) technical videos, this video has 60% more views than any other video over the past year. The runner-up was the "Licensing Essentials" video. Better luck next year. And the "Application Streaming and Isolation" video, uploaded last week, missed the entry deadline. Sorry.

Since Citrix admins are so interested XenApp design issues, I suggest taking a looking at the March 5 TechTalk webinar Designing Citrix Presentation Server Farms for Maximum Scalability. It will be hosted by Gagan Singh and Mike East who together have 21 years of experience working with XenApp and all the previous versions of the product back to MetaFrame 1.0. No doubt, we can all learn a thing or two from these guys. Here are their bios:

• Gagan Singh - Director, Product Development
  Gagan is responsible for quality assurance of the Citrix XenApp (the new name for Presentation Server) product line. He has been with Citrix Product Development for eleven years. Gagan has delivered over 14 Citrix products (from Citrix Metaframe 1.0 for Windows Terminal Server to Presentation Server 4.5, FP1). He created and developed the first scalability team dedicated to the testing of large farm environments. Gagan's team delivered scalability for four XenApp releases and grew the dedicated scalability test eLabs from 200 servers to over 2,000 servers over that time period.
  

• Mike East - Manager, Product Development
  Mike has been with Citrix Engineering for ten years. He is widely recognized as one of the world's foremost experts in Presentation Server farm architecture and design. He was also one of the original authors of the Advanced Concepts Guide. Three years ago, Mike assumed management responsibility of the scalability team dedicated to enhancing the robustness and resiliency of the Citrix XenApp Platinum Edition. Over a year ago, Mike assumed management responsibilities of the IMA development team which delivers the backbone of XenApp infrastructure.

UPDATE:  Yes, this year's "Citrix Oscar" goes to Brian Madden. Sorry for omitting that in my original post.  So Brian, when you're ready to make your acceptance speech, we're all-ears. I'll make sure the Academy Awards band doesn't start playing at 45 seconds 

Citrix is heads-down working on the launch of Project Delaware, the next version of Presentation Server. And Microsoft is finalizing launch details for its Heroes Happen Here launch events for Windows Server 2008 (along with Visual Studio 2008 and SQL Server 2008), which begins on February 27, 2008 in Los Angeles. At this event, you will see the new Terminal Services features first-hand, but don't wait until then to get a sneak-peek of some of those features.

With the upcoming release of these new products from Microsoft and Citrix, organizations are asking themselves with increasing frequency questions like:

• Will I still need Presentation Server?
• Will Terminal Services in Windows Server 2008 meet my needs?
• Why should I pay more for Presentation Server as compared to Terminal Services?

These questions are nothing new to the Terminal Services teams at Microsoft and the Presentation Server teams at Citrix. In fact, in my nearly 6 years at Citrix, these same questions are asked continually, and more frequently as we near product launches.  But the truth is, new releases of Presentation Server are **always** complementary to new releases of Terminal Services.  Maybe that's why Microsoft named Citrix Global ISV of the year in 2003 and again in 2005.

If you are considering Terminal Services and Presentation Server, are all of your questions answered in these items?:

• Value-add to Terminal Services
• Citrix Value-Add to Windows Terminal Services White Paper
• Performance Evaluation of Presentation Server 4.5 and Windows Terminal Services White Paper  

Will an update to these docs answer your questions? Or would you like to see something new?  What questions do you need answered when considering these products?
