Administrators are used to the idea, that running applications under Application Streaming will permit poorly written applications to run in a multi-user terminal services environment.   For example, if the application wants to write to the \Windows directory, no problem; the application will believe that it wrote there and later if it reads the same stuff, it will see what it put there and generally, the application will work. What is less known is that that Application Streaming and XenApp publishing can be used to reduce the rights of the application at execution so that it has a reduced chance of hurting the machine.

Privilege vs. Isolation

Isolation and "privilege" are different things. Running the application "isolated" does not mean that the application can't do powerful things.   An administrator privilege ISOLATED application CAN still perform privileged operations such as adding new users to the machine, marking them as administrators and adding them to the remote desktop group where the evil doer can then remotely login, as a non-isolated administrator and easily do evil things. 

Not a problem for XenApp hosted execution

To be clear, none of this is important for XenApp hosted execution.  Here, the user is already a user and stripping power from the user to get them to user power is a "nop" because they were a "user" to start with.  This discussion of "privilege" reduction is more of a Windows XP client side, or hosted desktop statement where "admin" power users are the norm.   On Windows XP, unless you're very good at locking down the machine the end user will be running as an "Administrator" and this is not desired.  How can you make this happen as little as possible?  How can you get MOST of the applications to run with the least privilege possible?

Brain damaged applications

Some applications even CHECK to see if they are admins and refuse to run if they are not.   Awesome!  If you can't figure out how to code it, demand admin rights machine wide!    You can easily hit a situation where 90% of your desktop applications will run fine without admin rights, yet you have no choice but to make the user a full blown administrator because some small subset of the applications demand admin rights; or perhaps, even really need them.

What about the "normal" applications that don't need admin rights, or at least don't need admin rights when run under isolation?  It would sure help if we could at least make the "all powerful" user be a "lowly user" for the purposes of the majority of application execution, even if the user is really an administrator.  You can, and XenApp makes this easy.  First, some history.

DropMyRigthts

Go back in time and take a look at this 2006 technet article from Microsoft on Least User Access and a description of the DropMyRights utility by Michael Howard.   Excellent stuff and here is a related set of blogs from Aaron Margolis of Microsoft who seems to have a passion for running apps as a user!   The output of this early work was a command line utility called DropMyRights which would duplicate the user's logon token, strip the powerful rights - and then use the modified token to launch the application.  Good stuff.  As an example, here is the .BAT file I used to use to launch MS Outlook.

• dropmyrights "%PROGFILES%\Microsoft Office\OFFICE11\OUTLOOK.EXE"

The idea of running apps on forced user privilege on Windows XP was not unique to App Streaming, but we did wrap pretty GUI around it and wrapped application publishing around it to make it easy to use - and then we didn't tell anyone it was there.  To be fair, most of the usage was server side, so it wasn't as important, but hosted desktops are changing this.

The XenApp publishing system makes this dropping of user rights accessible via easy to use GUI.

Access Management Console

Here's the AMC screen that controls this setting.  Notice that this "stripping of rights" is controlled in the AMC - not in the streaming profiler.  Could it be controlled in the profiler?   Sure.  Both of these tools are nice GUIs which could accomplish the same goal, so yes, it could be controlled in the profiler, but it isn't.  One could even make a really good argument that it is in the wrong place and SHOULD be in the profiler because this is where the admin is that knows more about the application.  I would agree, but it wouldn't matter, it's still in the publishing console whether or not this seems like the right place.  

 
When I wrote the draft for this post, I did it in a place without internet access, so I couldn't easily check the default.  I wrote that SURELY! the default is that we strip the rights before launching the app.  Surely, Shirley, what ever you call it, the default is the other way; by default, the launch leaves the user's token alone and launches the app using what ever power the user has according to logon.  If you CHECK the box, then the Access Management Console tells the Citrix IMA to tell the Citrix Web Interface to tell PNAgent to tell the Streaming Client that it should strip power from the user for the purposes of running this stream to client application.  Where the application will permit it, You should set the checkbox.

XenApp server side, it won't change anything;XenApp Client side, it will ensure that the application is launched using a user token that has "lower power".  Lower power is better...

While a mandatory based profile solution was the original approach (something we leveraged in the earliest releases), we are not going to return to that method. Let me explain why and get your thoughts and opinions on this.

One request that has been commonly voiced has been around a mandatory style implementation. While previously we had leveraged a mandatory profile as the base, for many reasons we moved away from that approach. One key reason was to save time that the merging process required (the copying of the mandatory down first and then copying of all the net changes). All in the spirit of logon speed. Another key reason is that it really was not a mandatory profile anymore. Profile management captured all the net changes from that base mandatory. So no settings were enforced or re-written at next logon. Basically it was a holder of starting settings when a profile was loaded. But the net changes were always re-applied over the base so nothing was ever enforced. So in the end, you needed to leverage Group Policy to enforce any permanent settings anyway.

It's also been explained that having a mandatory approach enables customers without Group Policy delegation to have a means to control the profile settings. And mandatory by itself is a great solution albeit the limitations on the breadth of personalization - which the amount of personalization afforded by a mandatory solution is probably adequate for many scenarios. While you can redirect folders like My Documents, Favorites, Cookies and others, the ability to change anything registry related is prevented e.g. wallpapers, application configurations and such. But if you try to combine this with something like Profile management to enable those changes, how are you going to restrict what does not get saved? You would need to create an exclusion list of all the settings you want enforced (and thus excluded from being saved). Doable on a few settings but it will get unwieldy really fast. And I am willing to bet it's going to be harder than Group Policy to manage before long. In the end, it seems capturing all the settings and using Group Policy to enforce setting as required is the way to go and thus the direction for our profile management solution.

Finally, let's address the capability of having a base profile to start with. We do offer a template profile capability which you could think of as a Global Default User profile. When a user logs onto Windows and does not have an existing profile (be it local, mandatory, roaming or TS), Windows creates a new profile for that user based on the Default User profile located on that current machine. The fun of this is unless you want to sync all the Default User profiles across all the machines a user might likely log onto for the first time, the starting profile will different (although often only slightly) from user to user. Might not be a big deal initially or on smaller scales, but will be more problematic as your environment expands and grows.

The purpose of the template profile is to enable a consistence starting point for a new profile being created no matter the machine. The template profile can leverage a copy of the mandatory profile you use today but you just need to rename the NTUSER.MAN back to NTUSER.DAT (so no you can't use the same one as both the template and a mandatory). And the template profile has to be complete (e.g. the entire directory structure and NTUSER.DAT). Also keep in mind that this is used for profile creation. So changing the template is fine, but only affects new profile being created and not existing ones. Need to change or enforce a setting for all users? Then we are back to using Group Policy for those situations.

So that is where we stand today with our Profile management feature (a feature of both XenApp (Enterprise and Platinum) and XenDesktop (Advanced, Enterprise and Platinum). Of course this is always open to debate and discussion if you have scenarios that illustrate weaknesses to this approach that Citrix should pay more attention to addressing.

We have had a great discussion going about user-installed applications and the need/risks associated with this type of solution. One of the comments I received in favor of allowing users to install applications was around Firefox. For those of you who don't use Firefox, there are thousands of add-ons a user can install to customize their browser experience. I personally have about five different add-ons configured with my Firefox implementation.

Now I've been advocating the need for IT to have a process in place that can handle the expansion of the application pool for the users as needed by:

1. Taking user requests for new applications/tools
2. Validating the need
3. Delivering in a timely manner

This is all well and good until we get to the topic of these add-ons. I don't expect any IT organization to have a requirement to support the add-ons. There are thousands of them. Think about it, do you really expect your IT to be spending time messing with these add-ons? And what would it look like for the user? A Firefox application with thousands of add-ons? CRAZY (I do wonder at what point that app would crash. Maybe need a MythBuster episode on it)

All of the sudden, I had a very enlightening experience. I just got my new XenDesktop 4 environment built. I went in an started to personalize my environment, including my 5 Firefox add-ons (remember I'm using pooled desktops from a single base image with roaming profiles). The next day, when I logged onto my virtual desktop, my Firefox starts up and BAM all of my add-ons are still there?!?!

I did some investigation into this. Well, this is an example of an intelligent application design. The add-ons are located within the user's profile (the roaming portion). User's are able to customize the Firefox application without any special tools/utilities. The discussion about Firefox and the add-ons is now a non-issue as the application manages this for us.

So, 1 application down, only 999,999 to go   The point is you need to test before deciding if something will or will not work.

With the release last month of HDX 3D for Professional Graphics as a feature of XenDesktop, Citrix now offers two alternatives for delivering high-end 3D graphics from hosted applications. Let's compare these two solutions.

HDX 3D Pro Graphics on XenDesktop

Our premier solution for 3D professional graphics is based on hosted Windows desktops and works with either the XenDesktop 3 or XenDesktop 4 Desktop Delivery Controller. HDX 3D Pro Graphics features our most advanced technologies for data compression, making XenDesktop the best solution on the market for delivering 3D graphics to remote workers. For top level performance, we offer GPU-based compression, leveraging NVIDIA graphics processors with 96 or more CUDA cores. The compression level is automatically adjusted based on bandwidth. Just below that is CPU-based JPEG XR compression (no special GPU required). JPEG XR (the 'XR' stands for 'Extended Range'), formerly known as HD Photo, is an ISO/IEC standard for high dynamic range image encoding. These compression options are supported by the HDX 3D online plug-in for Windows, a special version of the ICA client. With advanced compression and other clever innovations, HDX 3D Pro Graphics delivers a good experience even at 2 Mbps and 200 ms roundtrip latency. And, of course, it delivers a high definition "like local" experience on high bandwidth, low latency connections.

Application compatibility is excellent with HDX 3D Pro Graphics because the applications run on a standard Windows XP operating system (and Windows 7 support is in development). It doesn't matter whether the applications use DirectX/Direct3D or OpenGL or whatever. HDX 3D supports True Color, important when a very large number of colors, shades, and hues need to be displayed, as with high quality photographic images or complex graphics. Customers are already using HDX 3D to work with models with more than a million parts, and 64-bit OS support is coming soon, which will enable huge amounts of memory to be addressed.

These comments from our customers sum it up best:
• So far this is the only product to have anywhere near acceptable performance
• Everyone is loving it
• 50 to 75% better than our existing solution
• In pure Swedish, it is "sh$@#ing good"!
• At 1.5 Mbps it is still very usable
• We have been extremely impressed

HDX 3D on XenApp for Windows Server 2008

For many organizations, HDX 3D on XenApp provides a great solution for delivering professional graphics, since Windows Server 2008 now enables a graphics card to be used for 3D rendering on Terminal Services / Remote Desktop Services. While hardware acceleration is limited to DirectX/Direct3D-based applications, that may be all you need depending on the specific applications your end users require. OpenGL based applications are CPU-rendered but they perform much faster on 64-bit Windows than on 32-bit so you may find that to be adequate. Of course, if you really need hardware acceleration for your OpenGL applications, go with HDX 3D Pro Graphics on XenDesktop.

Compression options with HDX 3D on XenApp are not quite as extensive as on XenDesktop but are generally sufficient for intracontinental WAN access. The highest level of compression is obtained by selecting Heavyweight JPEG, a special variant of JPEG that uses arithmetic encoding instead of the normal Huffman encoding. It gives a further reduction in bandwidth of around 10 to 20% without changing the pixel quality at all (compared to standard JPEG), at the cost of higher CPU consumption. With Progressive Display, users get a responsive experience even over WAN/Internet connections because images are delivered with lossier compression while being moved and quickly resolve to full resolution when motion stops.

A single graphics card in the server can support multiple concurrent users, depending on their usage characteristics. I spoke with a customer using an entry-level NVIDIA FX 370 GPU and they support four concurrent users on an HP 360 G5 server with a dual-core Xeon processor and 4 GB of memory running 32-bit Windows Server. They estimate that they will be able to support 12 to 16 simultaneous users on a dual quad-core server with 64-bit Windows Server and 32 GB of memory. Again, it depends on the application and the work profile of the users. A more powerful GPU, like the NVIDIA FX 5600 or 5800, will help with scalability, too.

HDX 3D on XenApp supports lossless compression (important in Healthcare), but color depth with DirectX hardware acceleration is currently limited to 16-bit High Color. True Color support (16 million colors) is offered with CPU-based rendering, and True Color with GPU hardware acceleration is planned for the near future, making HDX 3D on XenApp a great option for delivering PACS applications over hospital campus networks.

A Look Ahead

How will these technologies evolve in the future? 64-bit Windows XP and Windows 7 support is planned for HDX 3D Pro Graphics on XenDesktop, and True Color support is coming soon for HDX 3D on XenApp. Windows Server 2008 R2 is likely to bring some benefits, too. And as the graphics and hypervisor vendors introduce GPU virtualization, we expect to leverage that on both XenApp and XenDesktop; some exciting progress in this area is already happening in the lab. Expanding the VM Hosted Apps feature of XenApp to encompass 3D graphics apps would be a natural step.

Tell Us about Your Experience with HDX 3D

If you're using either of the HDX 3D technologies described above, I'm sure other customers would like to hear your story. Please tell us about the 3D applications you deliver, your data center and network, and how your users are benefiting.

Citrix XenApp 5 Feature Pack 2 for Windows Server 2003 has a very cool feature called Secure Clipboard Control. The technical folks may know this feature as "Read-Only Client Drive Mapping and Clipboard", but the end results are the same: it further mitigates risks of data leakage.

Granting remote users CDM access is great because they can open local files with server published apps. But they also have the ability to save server documents locally thereby increasing the probability that confidential data leaks out beyond the enterprise. Some customers have tried to tackle this problem by disabling CDM and clipboard altogether, but that does not offer users flexibility - what if administrators want to only let users save documents back on the server? This is where the new Secure Clipboard Control setting can help. It is a really simple feature for administrators to configure, yet provides an added level of flexibility (users can save documents to the server, but cannot save documents to the local device) administrators didn't have before.

To enable the feature in the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdm\Parameters, create a DWORD value with value name ReadOnlyMappedDrive and value data 1.

To enable one way clipboard In registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard, create a DWORD value with value name ReadOnly and value data 1.

After rebooting the server all users that connect will only be able to read documents from their mapped drives and will only be able to copy and paste text into a published application. Data that is copied into the published application clipboard (via CTRL-C) will not show up in the client's clipboard paste buffer. Whenever the user tries to save a file to a mapped drive they will get an error saying they don't have permission to write to the location because XenApp has the drive open in read-only mode.

For now both settings are server wide so remote users will have to be confined to specific machines where the settings are enabled. You can find out more about this feature at CTX123002 and in Citrix eDocs here.

As the first opportunity to really interact with customers and partners on a large scale after the XenDesktop 4 and FlexCast announcements, Tuesday's CitrixLive!was a really exciting day for many of us at Citrix.  Ron Lott, Frank Anderson and I had the opportunity to do the Q&A sessions for FlexCast, our name for the uniquely numerous methods Citrix has of delivering virtualized desktops and applications, all under one product, XenDesktop 4.  As my XenDesktop counterpart SME, Frank is an incredibly savvy technologist and fellow Citrite, with a rather impressive employment history with some of Citrix's largest and most successful partners, customers, and XenApp rollouts.  I knew him when he was at Disney and Emory, but have really enjoyed watching him work over the last couple of years in a vital role on our XenDesktop product team... just a great guy to work with.  But I digress...

Back to FlexCast and the delivery options:

Simply put, FlexCast is all about enabling the broadest class of capabilities under a single product from a single vendor, in order to enable IT buyers and engineers to focus on the right implementation for their environment and users, without getting caught up in what many are finding to otherwise be a costly, multi-vendor solution that usually doesn't quite cut it.

After some of the questions on FlexCast during the CitrixLive! Event on Tuesday I thought it would be a good idea to start a blog series about FlexCast On-Demand Apps by presenting the matrix of application and desktop delivery options included in XenDesktop 4.  Dan Feller has posted a quick video over in his "Ask the Architect" Blog that goes into this as well.  Dan's posts are always a great resource so please check them out.  In follow on posts we will go into more detail about specific implementations from this matrix, which grows much larger when you take into account that some users actually use multiple desktops and scenarios, sometimes all at the same time.

In the matrix I have included traditional installation as "End-point Installed", not to include it as part of FlexCast, but to acknowledge it in perspective to the options enabled by FlexCast. 

I have also separated "Online streamed/app-v" and "offline application streaming/App-V" in order to clarify the target platform for these on-demand delivery types. "Offline" in the Citrix vernacular describes the ability of an execution platform to run an isolated app without requiring an active connection to to a back-end XenApp server. 

App Type \ Desktop Type	Hosted Shared Desktop	Hosted VM-Based Desktop	Hosted Blade  Desktop	Local Streamed  Desktop	Local VM-Based  Desktop	Installed Desktop
Online Installed
Online Streamed to Server
Online App-V Streamed to Server*
Offline Application Streaming
Offline Microsoft App-V**
End-point Installed***		3rd Party	3rd Party	3rd Party	3rd Party	3rd Party

    * Requires Microsoft VDI Suite - Premier
  ** Requires Microsoft VDI Suite - Standard
*** Manual or 3^rd Party ESD installs are not part of FlexCast 

As you can see, there are 28 discreet options to be considered for any single desktop implementation. This can at first sight be a little overwhelming.  I would argue that this is much less overwhelming than being forced into one particular desktop or application delivery solution and then trying to address all of the complexities of a growing number of access scenarios (i.e. are all of the users on campus? How many branches do we have to serve and what are the idiosyncrasies of each one?  What do you mean the CEO is working from a remote island with crappy internet access, next week, but still wants to work like they are on the dedicated 10Gb link we installed in his office yesterday)  OK, maybe that last one was a bit of an exaggeration, but you get the point. 

With all of the other considerations to take into account, being hobbled by any solution that can only address the problem in a single, specific way, because that is all it can do, is often like painting a car with push broom, yep the paint will go on, but is the end result really what you were hoping for?  Citrix FlexCast pretty much covers every consideration that needs to be taken into account for cost effective desktop and application delivery.  Especially in light of current economics and increasing budget constraints, let alone consumer based end-user expectations that are outpacing the current capacity of corporate IT to deliver acceptable usability and service levels.

In the flexibility line of thought and in light of all of the pressure we are all under in a down economic climate, I'd like to share an excerpt that hit me from one of my favorite books while I was looking at this matrix and reflecting on the great opportunities that On-Demand Apps and XenDesktop 4 introduces.

All three quotes are from one book, they are not in sequence but they cover three thoughts...

The opportunity: 
"Congratulations!
Today is your day.
You're off to Great Places!
You're off and away!
You have brains in your head.
You have feet in your shoes.
You can steer yourself any direction you choose.
You're on your own. And you know what you know. And YOU are the guy who'll decide where to go."
 
The Trap to avoid:

"You can get so confused that you'll start in to race down long wiggled roads at a break-necking pace and grind on for miles across weirdish wild space, headed, I fear, toward a most useless place.

The Waiting Place...for people just waiting."
 
The Reward for getting it right:

"Oh! The Places You'll Go!

You'll be on your way up!
You'll be seeing great sights!
You'll join the high fliers who soar to high heights.

You won't lag behind, because you'll have the speed. You'll pass the whole gang and you'll soon take the lead. Wherever you fly, you'll be best of the best. Wherever you go, you will top all the rest."

Wow, I almost feel like Stuart Smalley after that one, anyway thanks for allowing me the tangent, and oh yes, thanks Dr. Seuss, one of the 20th centuries greatest philosophers!

Now, back to business... I am looking for the community to help this blog series evolve by asking questions, sharing examples, and pushing us to deliver more in those areas where you have real pain but no real solution yet.  These are the things that I would really like to be talking about, so let's have at it!

I was away for a couple of week, but I'm back and very excited to tell you about the HDX Plug-n-Play for USB storage device. HDX Plug-n-Play for USB storage is another HDX/High Definition eXperience feature introduced in XenApp 5 Feature Pack 2. I believe this new feature will really eliminate many headaches for XenApp administrators and end users alike. So imagine, users now have the ability to plug-in their USB thumb drive/USB stick and use it with their XenApp delivered application at any time; before launching the application or while they are in the middle of working with the application. Effectively, users now have a local-like experience when interacting with a USB stick or USB disk drive.

For those not familiar with how USB storage worked prior to Feature Pack 2, let me explain... Let's say you are working with Microsoft Powerpoint delivered to you via XenApp. A co-worker stops by, hands you a USB stick and asks for a copy of the Powerpoint. Naturally, your instinct tells you to plug in that USB stick, go to Powerpoint - File - Save As... <bzzzz - wrong!>. Prior to Feature Pack 2, users must first plug in the USB stick before starting the Powerpoint. Otherwise, XenApp would not recognize and map the thumb drive in the session. Needless to say, it's not very natural, and couldn't be any less instinctive.
Many customers & admins I talked to are raving about this new feature in XenApp! They are excited because they no longer need to "re-train" users how to use USB drives with XenApp. IT no longer have to field support calls on why they don't see the USB stick in the application. Applications delivered with XenApp become ever more transparent to the end users...and that's a great thing!

How do I enable this feature? This feature is enabled by default. So, if you have policies to not allow use of USB sticks, you'll need to disable this feature in the registry by following the instructions below or in eDocs.

On XenApp 32-bit edition
HKEY_LOCAL_MACHINE\Software\Citrix\Policies\DisableUSBRedirection
On XenApp 64-bit edition
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Citrix\Policies\DisableUSBRedirection

Type: DWORD
Values:
1 = redirection disabled
0 = redirection enabled

Now, I also want to point out that this feature, like the HDX MediaStream for Flash is currently available on XenApp 5 for Windows Server 2003. Support on Windows Server 2008 is forth-coming and I'll be sharing more information on this site in the near future.

So, there you go... XenApp 5 Feature Pack 2 makes life easier for admins and end users, again! And if you missed my first post on how XenApp 5 Feature Pack 2 delivers a local-like experience with Adobe Flash content, take a look at HDX MediaStream for Flash
But wait! Tomorrow, Ola Nordstrom from our Security team will post our HDX Easter-egg feature called Secure Clipboard Control. Very cool feature for customers who require better control of information flow in an XenApp session. So, stop back tomorrow!

It's been a very hectic week and a bit since Citrix announced XenDesktop 4. As owner of the Trade-up to XenDesktop 4 program for XenApp customers, I have been fielding lots of questions from partners, analysts, customers and Citrites as the word has been spreading rapidly. I thought it would be a good idea to follow up with a blog post series that captures many of the questions and answers.

Before I get into the first question, let me do a quick refresher on the program. First, the program is designed to make it very easy and attractive for any XenApp customer to trade-up to XenDesktop 4. Any customer, who is current on Subscription Advantage (SA) that Trades-up all their licenses to XenDesktop 4 at once, gets 2 XenDesktop 4 user or device licenses for every 1 XenApp concurrent license. The pricing is such that they save 80% off the purchase of new XenDesktop 4 licenses. If a customer doesn't want to trade up all their licenses at once, they can trade-up a portion of them and receive 1 XenDesktop 4 user or device license for every 1 XenApp CCU. Pricing is set such that the customer saves up to 70% off the purchase of new XenDesktop 4 licenses. In both cases, customers can use their existing SA renewal budget to fund the bulk of the Trade-up. This program is similar to the Upgrade to XenApp Platinum that we introduced to coincide with the launch of Platinum in Q1 of 2007 and was very well received by our customers. In fact approximately 70% of the upgrades to Platinum happened at SA renewal time.

If a customer has expired SA, no problem. They can Trade-up any Enterprise or Platinum licenses going back to MetaFrame XP. Pricing is set such that the customer saves up to 50% off the purchase of new XenDesktop 4 licenses.

In all cases, customers get another year of Subscription Advantage and when they renew, they do so at the lower XenDesktop 4 rate.

One of the first things that comes up is - "who should consider the Trade-up?" Before I answer, consider the following two key points. XenDesktop 4 contains all the functionality of XenApp (including the latest goodies introduces in XenApp 5 Feature Pack 2 like VM Hosted Apps, HDX enhancements for Flash and Power and Capacity Management) as well as all the latest XenDesktop 4 features (such as FlexCast Delivery Technologies). Customers who Trade-up and implement XenDesktop 4 can leverage all their XenApp experience to deliver apps the way they always have and full virtual desktops as well. What is even cooler is point two. If you Trade-up your licenses now, you don't have to implement XenDesktop 4 until you're ready. Your current XenApp implementation will run on your new XenDesktop 4 licenses. You can update your infrastructure when you're ready. One last little pitch. XenDesktop 4 works with any existing storage management and server virtualization infrastructure (including VMware).

All that said really any customer who has a concurrency ratio of 2:1 or less or multiple users per device should consider the Trade-up. If your organization is thinking about desktop virtualization now or in the future, you should consider the Trade-up. If you're about to embark on a desktop refresh with Win 7 and are looking at ways to reduce desktop management costs, consider the Trade-up.

Let's look at an example of a customer who has 1,000 licenses of XA Platinum at a 2:1 concurrency ratio and is considering Trade-up (Please note that prices here are SRP. No volume discounting has been applied). Of course, first thing they would do is go to the Trade-up calculator to check out the dynamics. If the customer Trades-up 100% of their licenses, they'd get the 2-for-1 and would have 2,000 XenDesktop 4 user or device licenses. To fund the Trade-up, they'd take their $50,000 of budgeted SA renewal and add $45,000. Now they have the ability to deliver full virtual desktops as well as applications. The renewal rate of SA the following year would be based on the $35/user or device and would be $70,000. Not bad considering they have more than twice the functionality they had before and double the number of licensed users or devices. Plus, the licensing flexibility gives the customer to provide access unlimited virtual devices per user or unlimited users per virtual device depending on whether they choose a per user or per device model.

We worked hard to make it easy for our customers to add desktop virtualization to their working XenApp implementations, to minimize risk and to reward them for their loyalty.

Probably enough for the first post. More to come.
