TechAgility

So as things slowdown in the lead up to the break I have had some time to get back and review some twitter posts and other blog articles that I have been meaning to catch up on. I must admit that I tend not to use Twitter that much but do find it quite useful as pointers to additional material for research and recently posted material on the topics that I’m interested in.

So one article that really caught my eye was this from Ruben Spruijt’s post at Brian Madden, because for a number of years now it is the Hard Drive that has not kept pace with advancements in technology for the rest of the PC/Laptop components, and in particular I have noted a number of people getting very enthusiastic about the performance improvements they have actually noticed when using Laptops with SSD’s

Runcore SSD’s – promises to boost computer performance vs. the traditional 1.8" HDD by more than 400% with read/write speeds up to 75/40MB/sec.
Experience with 128GB 1.8" ZIF in HP 2710p – Read/write performance for 4K random files has improved over 500% (even under Bitlocker). it just became the fastest computer I ever used… Word and Excel launch in one or two seconds (compared to 30-60 before)…

Just how fast does the storage component of VDI have to be?
So it stands to reason that if you are going to Virtualize your Desktops (and by definition centralize?) then you are going to need to give some serious throughput for the Disk I/O or IOPS? So for anyone who is embarking on this then I would seriously recommend giving this article a through read? Understanding how storage design has a big impact on your VDI!

Possibly the most interesting point that Ruben did bring to my attention with this is that in VDI implementation the Disk I/O is predominately Writes and not Reads – I know this sounds contradictory in some respects, but do review this for yourself – in particular is a good comment from Claudio Rodrigues regarding the nature of how the O/S’s deal with this, as well as confirmation from Dan Feller at Citrix who confirms that most of the numbers and math are in sync with his findings. Ruben has also supplied a Sizing Tool to get a good idea of what might be needed?

So it also starts to make sense that you make sure that you focus very sharply on the XP or Windows 7 Template VM’s in the first place to reduce the I/O required as much as possible?
Citrix has some great tips in this document - Best Practices – Citrix XenDesktop with Citrix Provisioning Server

So as this brought up some interesting thoughts I also found this article relating to sizing and best practices, VMware View sizing & best practices
which followed on from this original article Virtual Infrastructure best practices and in essence this confirms that the storage requirements will need to focused somewhere around an 20/80 split on the Read/Write (20% read and 80% write)

While this table gives a quick representation of what sort of sizing requirements are out there please make sure you research this subject thoroughly, and read the post in full? J

In all fairness I must also confess at this point that my weakest area in IT is storage, and as yet I have not had a functioning Lab running either Citrix’s XenDesktop or Vmware’s View to be able to play around with this and get my hands dirty with either Provisioning Server or Composer. From what I can see (based on Marketing so far J) both of these products have the ability to drastically minimize the storage needed for VDI and as a consequence I am assuming that this may indeed have a flow on effect to mitigating the IOPS issue? (Can anyone comment or set me straight on this?)

I then went on to find some more details around the costing and financial side of VDI implementations and found this article of Doug Brown’s regarding Cost Savings of VDI: Is It Possible? as the diagram below points out, it is complex, and as such it could be that the regular ROT/TCO calculations are not highlighting all the potential benefits and savings?

Changing the ROI/TCO Calculation?
So this then brings me to another update in my Twitter was from Tyler at LiquidwareLabs.com with a new addition to the ROI/TCO debate,
COP – Coefficient of Productivity in VDI the New Math , in which he points out that you should also factor in any additional productivity gains and use this to dilute the true cost of the CAPEX.

Now I wonder how many VDI proposals are brave enough to start assigning values to what has traditionally been seen as "additional" benefits related to an architectural change? Don’t get me wrong, I’m not against it, but I can see the debate might start to get a bit heated in the boardroom? and in some respects maybe that’s exactly what’s needed – by assigning values and assumptions and then extrapolating them across an enterprise the resultant *potential* savings become too hard for the board to ignore?

Sure there will be debate, and rightly so, but in following this sort of process it should quickly become apparent that there is a technological shift under way where the concept of "My Desktop" still being something that can be pointed to in the Office sitting on a desk somewhere is rapidly becoming redundant?

Now having said all that – it’s interesting to note that Gartner’s Hype Cycle Report for 2009 seems not to have VDI listed? Maybe it’s hiding under something else here?

So will VDI make it to "mainstream"? AMD seems to think so, Taking Desktop Virtualization Mainstream, but also a lot of it will depend on a number of factors.

My main thoughts on this are:

To truly succeed VDI needs to be able to deliver a *High Fidelity* User experience equal to or better than what users have today – if what you are designing is unable to provide this then you should stop and re-evaluate now

If you can build a system that is able to provide this then users will want (no, Demand!) that they have it ASAP – you will know that you have succeeded when demand outstrips supply

To provide this *High Fidelity* User experience I’d suggest focusing on two key areas that may/or may not apply depending on your particular focus and what is considered in or out of scope for your project?

• Graphics
  
  • Bottom line – Graphics performance in this design CANNOT be measured, it has no metrics, or Best Practices. One persons "that’s fine" is another persons "there is absolutely no way I’ll put up with that", etc. This will always be a completely subjective assessment based on whoever is rendering the judgement.
  • You may think that you don’t need to focus too much on Graphics because "there isn’t much need or requirement for Video from the business" but I can almost bet that you would be wrong – if you are operating on this assumption be sure that you double-check with Stakeholders and get their agreement in writing?
  • So much content on the Internet is done in Flash today, it’s not just watching a CEO or Analyst briefing via YouTube, a lot of Web Based Training modules use the same or similar technologies, so even if you currently block YouTube and Facebook today it’s still quite likely that you need to factor this in to your design
  • Is RDP good enough? Check this assumption by giving targeted business users a Thin Client and removing their desktop to the lab and forcing them to access via the Thin Client – this is a simple but effective test that validates whether they truly need/demand High Fidelity, or will OK Fidelity do?
  • Do you need Citrix HDX? PCoIP? RGS? While I’m making the point about Remote Protocols – don’t forget to gather details of connecting accessories? Do you need to support serial or parallel?
• HDD or IOPS
  
  • Make sure the VM performs as well as possible while measuring the I/O on the VM itself? Check the disk queue, and ensure that it’s not the disk performance that’s holding this back – and make sure you have enough throughput to allow for Login’s etc.

So where does that leave us?
In the Graphics space there is already a number of solutions for VDI that have been out for some time (Citrix’s HDX) or have recently been released (Teradici’s software version of PCoIP). In addition to that there are other approaches if you need to support High Fidelity Users at the top end with HDX-3D taking advantage of Nvidias GPU’s that almost bring TeraFLOP performance to the Desktop.

A good introduction to CUDA – Just how powerful can GPU’s be? Back in mid-2008 the GT200 was able to deliver 1 TeraFLOP performance, the G80 supports 768 Threads per Core – on 128 Cores… Want a Personal Supercomputer? What would you use it for?

So I suspect that we are not far away from seeing vGPU’s being available to VM’s that will be able to deliver the performance on demand – the main thing is that you make sure you are either using a Remote Protocol stack that can provide this functionality – OR make sure you are using a Broker that supports a shift to one?

At the HDD level I’d suspect that as SSD prices come down and SSD longevity increases, along with improved methods of utilising this in some kind of shared caching mechanism in a VDI deployment we may well see some serious advances that enable VDI to overcome this IOPS roadblock?

With the monotonous regularity of Moore’s Law driving CPU performance up it should be possible to provide way more CPU power to users than they really need to enable this – but again – it’s quite possible that the Disk I/O that has the potential to spoil this party?

Please feel free to correct any of my ramblings?

So along with Alessandro I’m curious as to why the name ThinApp has been chosen as it does have more than a passing resemblance to Citrix’s new XenApp?

I wonder if this is any indication of the coming marketing campaigns in the push for customers attention in the Desktop Virtualization market?

VMware ThinApp is the final name for Thinstall technology

In January 2008 VMware, a hardware virtualization company, acquired an application virtualization startup called Thinstall.
The plan is to use the Thinstall technology to stream virtualized applications on the virtual desktops that VMware spawns through its connection broker: the Virtual Desktop Manager (VDM).

So fare VMware has been pretty fast in rebranding the Thinstall Application Virtualization Suite: the beta program for the new version is open since end of February and the testers can already download the beta 2.
The final version of the product, temporarily called Project North Star, is expected for the H2 2008.

The only information missing so far was the final name that VMware wants to use.
Now Micheal Keen, Director and Senior Solutions Architect in the Enterprise Architecture group at Alliance Technologies, reveals that the final name is ThinApp.

Duncan Epping further validates the news reporting that a former Thinstall employee confirmed.

The choice is interesting considering that Citrix just renamed its Presentation Server product in XenApp.

It is something of a shame that Symantec is not making the best of this acquisition, especially when you consider the amount of change and hype in the Virtualization space over the last 14 months since Symantec announced the purchase?

I made the comment only a few weeks ago (Thinstall quick out of the blocks) that it was quite gratifying to see good technology not sitting by the sidelines waiting for the politics and marketing to settle before it can again back on with getting the work done – but in this case it looks like Symantec are still dragging the chain?  

Symantec creates an Endpoint Virtualization Business Unit

Friday, March 21, 2008   |   0 Comments

After over one year since the acquisition, Symantec is finally operating the integration of Altiris in its corporate departments.

It’s not clear anyway if and in which way the security giant will pitch the successful Altiris application virtualization product: SVS.

The subsidiary in fact will disappear inside the Symantec Security and Compliance department, while a brand new Endpoint Virtualization department will be created, as reported by eWeek.

There are no details available yet but this reorganization may mean just two things:

• the first option is that Symantec plans to use SVS only to deliver virtualized versions of its endpoint security agents (the anti-virus is probably the first in the list)
• the second option is that Symantec will seriously enter the corporate desktop virtualization market, a space where VMware, Microsoft and few others are already busy with VDI, application virtualization and virtual machines security wrappers

In the first case Altiris SVS would be clearly out of the application virtualization market. In the second case Symantec may soon need more than just SVS to compete with the other players.

So this certainly adds some ammunition for VMware’s coming stoush with Microsoft in the Battle of the Hypervisors?

It makes you wonder who’s next on VMware’s radar?

VMware acquires Thinstall

Just yesterday virtualization.info published the news about a possible acqusition of VMware in the application virtualization market, speculating that the acquired firm could be FastScale.

The official announcement comes today, clarifing the actual acquired company and the company strategy behind the move:

VMware, Inc. , the virtualization software leader, today announced it has entered into a definitive agreement to acquire Thinstall, a privately-held application virtualization software company headquartered in San Francisco. VMware is acquiring Thinstall to expand its desktop virtualization capabilities which help customers better provision, deploy and update desktop environments. The terms of the acquisition, which is expected to be completed in the current fiscal quarter, subject to customary closing conditions, were not disclosed…

The acquisition of Thinstall and its use for VDI scenarios extended the competition front with Microsoft (which acquired Softricity application vendor in June 2006) and Citrix, and brings the company a notable set of OEM partnerships: with LANDesk (March 2007), with Provision Networks (July 2007), with BMC (September 2007) and with Macrovision (October 2007).

Given the strong focus of Thinstall on Microsoft platforms, the acquisition seems to validate an important point, often emerging in surveys: large majority of virtual machines contain Windows guest OSes.

At the same time this acquition validates once and forever the fact that application virtualization is considered one the next mainstream technology for most major players: before VMware, Microsoft acquired Softricity, Citrix acquired Ardence, Symantec acquired Altiris and even Google acquired GreenBorder.

Thinstall is the 7th acquisition for VMware. Before it the virtualization player acquired Akimbi (June 2006), Propero (April 2007), Determina (August 2007), Dunes Technologies (September 2007), Sciant (October 2007) and Foedus (January 2008).

If the trend continues VMware will acquire a new company per month.

I’m afraid I haven’t had time to actually download the docs and read them through as there are other things I need to get done before heading over to Vegas for Citrix’s Application Delivery Expo next week.

But it would appear that the Guide for Softgrid has come at a very opportune time as I’ve been contacted a couple of times now in the last few weeks by recruiters looking for people here in Australia with experience in Softgrid, in fact a few weeks ago I was contacted by a recruiting firm in Hong Kong who was looking further after they had received little response locally

Well it’s not much of a surprise that we’re not likely to see a replacement for Windows XPe any time soon? Well apart from an update based on SP3, but clearly it’s going to be some time before we see Vista based version of embedded? But I must confess that while reading through some of the details I was starting to get concerned that we are almost mimicking the bloatware that is afflicting the regular PC’s, Laptop’s and Servers?

Microsoft plots embedded OS futures

Oct. 09, 2007
In his keynote at the Embedded Systems Conference (ESC) last month, Kevin Dallas, GM of Microsoft’s Windows Embedded unit, tipped some of his group’s future product plans. Included are new versions of Windows CE 6.0 and Windows XP Embedded, plus the arrival of "Windows Vista Embedded."

Before detailing these, Dallas began his talk by providing "examples of where we could improve as an industry." Devices need to be service-aware, he said, citing telephony and navigation as examples.
It should be possible to use a mobile device to receive a phone call at home via VoIP (voice over IP), have it automatically switch to a WAN (and hands-free operation) when moved to a car, then seamlessly switch over to a corporate WLAN at the office, said Dallas. Similarly, he added, navigation devices ought to move information from a PC, to a mobile device, to an in-car system automatically.
Dallas noted four key trends that Microsoft is trying to develop its embedded technologies around, according to Dallas. These are:

• The "Software Plus Service" concept. "We can no longer build software that just sits on a device," he said. "Instead, we have to build software plus a service."
• Next, is a move away from just ramping up clock speed, and toward having multiple heterogeneous cores on a single chip — an applications processor, a graphics processor, and a radio processor.
• Then there’s the trend toward loosely-coupled services. Today, a device such as the Zune portable music player (PMP) is tied to a single music store, while a set-top box might be tightly coupled to a specific video-on-demand service. "In the future, these devices will be able to discover and connect to other services," Dallas said.
• "Finally, of course, there’s service-oriented development," Dallas continued. A service that a device is connecting to "may be on the same device in another core, it could be on the circuit board, it could be on the premises where the device sits, or it could be connecting out … to a web service that’s, frankly, on the other side of the world."

Visual Programming Language (VPL)
Dallas continued his keynote by revealing a new tool called the Visual Programming Language (VPL), with demos by Windows Embedded software architect Mike Hall. "Many developers think of building embedded operating systems in terms of technology stacks … What we’re suggesting is that you start to think at a much higher level," he said.
VPL will allow developers to use a graphical user interface to link services together, explained Hall. It will then be possible to determine at build time whether these services are going to run on a single device or on distributed devices, he said.
Hall added that, "As you start to link the inputs and outputs of services together, you are dynamically prompted for the inputs and the outputs that you want to match … The tools will be smart about determining the matchup between the output of one service and the input of another."

Windows Embedded Roadmap

Windows CE 6.0 Release 2 — Nov. 15, 2007, with Web Services on Devices (WSD), enhanced VoIP, and AJAX support

Windows XP Embedded — sometime in 2008, based on Windows XP Service Pack 3, including .NET Framework 3.0, an updated Media Player, and an RDP (remote desktop protocol) 6 client

Windows Vista Embedded — in 2009 or 2010, a componentized version of Windows Vista

New versions of Windows Embedded
Dallas then detailed future releases of Microsoft’s embedded operating systems. First among these will be Windows CE 6.0 Release 2, scheduled for release on Nov. 15, he said.
According to Dallas, this release will add AJAX (asynchronous Javascript and XML) and "heavy data entry" support in the browser. It also will include enhanced VoIP functionality, such as three-way audio and video conferencing.
The most key feature, according to Dallas, is Web Services on Devices (WSD). This is already included in Windows Vista as a native stack; it’s said the addition of it to Windows CE 6.0 Release 2 will allow communication between the two.
A manage code runtime environment, such as .NET Compact Framework, is no longer required, according to Hall, who also provided a "bubble" demo of graphics on a Vista machine being controlled by a Windows CE device. Instead, Hall said, WSD applications can be written in C or C++.
The second OS update, scheduled for "2008" according to Dallas, will be an enhancement to Windows XP Embedded based on the forthcoming Windows XP Service Pack 3. It will include .NET Framework 3.0, an updated Media Player, and version 6 of the Remote Desktop Client (RDP), he said.
Finally, "Windows Vista Embedded," a componentized version of Windows Vista, akin to Windows XP Embedded, will appear in "2009 or 2010."
Dallas concluded by saying, "You’ll see this common theme of new releases every two years. In between, you’ll see updates in components to drive differentiation, and updates in tools."
"We’re going to continue our ongoing investment [in embedded]," he promised. "We realize what our role is going to be around platform tools and services that enable these smart, connected service-oriented devices. So we’re going to continue to drive leadership in that area."

Brian Madden and Gabe Knuth have been looking deep at a possible VDI Solution for a University and they have shared their experiences, I must say it’s an Excellent Post – nothing like igniting the fires just before iForum?

On Brian and Gabe’s behalf I take exception to those who have commented on this post and are giving them a hard time on their *recommendations* to the University – especially those who feel free to shoot them down without offering any other alternative AND simply hiding behind the "Guest" ID

It is great to see someone come out and be completely open about this process and bring it to the public domain where we can all have our 2cents worth – and for this they deserve and have my thanks, as we’re all trying to keep up with all the multitude of different options and potential solutions to help customers get the most out what they’ve got.

This is seriously only a small section of this, if you have any interest in VDI Solutions you should take the time to read through the full Post and all the comments

VDI for hundreds of apps and thousands of users? A case study where we recommended this instead of a Terminal Server-based solution

Posted by Brian Madden on September 26, 2007.

A very strange thing happened yesterday. Gabe and I were working with a customer—a university—and we ended up recommending a VDI solution instead of a Terminal Server-based solution. Afterwards I was feeling, “Wow! I can’t believe I just did that!” But I really feel it makes sense. And in fact I think it might continue to make sense more and more, and now I’m wondering if VDI can start to come out of the niche and into the mainstream?

Let’s start at the very beginning. Gabe and I worked with this university six months ago. They were not using any server-based computing or streaming or anything like that. It was a brand new environment. They had four scenarios (or “use cases”) they wanted to enable:

1. There are 1200 lab workstations throughout campus. Users need to be able to walk up to any one of them and access any of 200 applications. The users also need access to their own data and profiles.
2. They want to publish a remote desktop via server-based computing to people so that they can access the “lab workstation” from their dorm rooms or off campus.
3. They want to publish individual applications (as opposed to a full desktop like in Scenario 2) to users on their own computers.
4. Longer term, they want people to be able to run these applications locally on non-university-controlled workstations (i.e. student laptops), and they want this to work offline.

The initial plan

For Gabe and me, these four scenarios were perfect for a combination of traditional Terminal Server-based application delivery and application streaming.

We were thinking they could use something like SoftGrid to isolate and stream all (or most) of their applications. Then they could add some Terminal Server and a third-party application publishing tool to deliver individual applications. Our initial suggestions for each scenario above were:

1. Use SoftGrid to stream the applications so they run locally on each lab workstation. Install the few non-SoftGrid-compatible applications natively on the workstations.
2. Use Terminal Server, along with Citrix Presentation Server or one of the cheaper alternatives, to publish server-based computing desktops. A combination of SoftGrid and local installs would be used to get the applications onto these Terminal Servers, much like the lab workstations.
3. The same Terminal Servers, running Citrix or whatever, can be used to deliver seamlessly published server-based applications to desktops and laptops.
4. For the applications that can be sequenced with SoftGrid, they could also be streamed to Windows clients for local offline execution.

That was our recommendation and plan six months ago. Let’s look at how that worked out.
