Desktop Virtualization Savings: It's in the Approach

One of the things we keep hearing from prospects about desktop virtualization is cost. In fact, in a meeting with our CIO Council this spring, the CIO of a major Wall Street bank said this firm’s investments in a virtual desktop infrastructure (VDI) solution had so ballooned out of proportion and the experience had been so painful that it’s left permanent bad taste in everyone’s mouth. There’s no way, he contends, that he could ever sell “desktop virtualization” to his firm again – management and end users alike.

That point really inspired us to work on a TCO model – so companies know what the costs entail before they commit to a desktop management path. Fundamentally, desktop virtualization is about easier desktop management and cost savings the icing on the cake.

In our TCO calculations, we show how MokaFive can dramatically cut desktop TCO by at least 45% by delivering savings in three areas:

1. Operational costs;
2. Helpdesk costs; and
3. Capital costs.

Operational Savings. MokaFive’s management model -- central management and distributed execution – is unique in the market, and critical to lowering overall TCO. The IT administrator creates one golden image, called the LivePC, which is sent down to thousands of users. To patch or update OS or applications, IT updates the single golden image in a central location, and automatically the changes are distributed to users’ machines. Contrast that to traditional software distribution, which requires every endpoint to be individually patched which can result in errors, complications and costs. (It’s no wonder companies are dreading the Windows 7 migration – and I am not at all surprised by the costs.)

Helpdesk Savings. MokaFive also delivers savings in helpdesk costs. Typically the most expensive calls occur when a user corrupts their machine with a virus. With MokaFive’s rejuvenate capability, a corrupted desktop can be “rejuvenated” back to its pristine state with all personal data intact – all with just a click of a button. The user doesn’t have to even make a helpdesk call or be online. The CIO of one of our earliest customers – a major law firm in Silicon Valley – recently raved to me about the unexpected savings in their helpdesk costs. They hadn’t even calculated it into their models (nor we, for that matter), but we now expect them to have paid for their initial investment in the next year.

If not for MokaFive, this customer’s helpdesk would be fielding level two and level three calls when a user corrupts their machine with a virus. This specific case calls for a desktop re-image, which can be a very cumbersome process taking hours, if not days to complete. When you re-image the machine, IT needs to supply a new OS, restore all the applications, and then re-apply all the user data.

We estimate steady state this is going to be true whether it’s a VDI instance or with software distribution because even in a VDI scenario the user has to make a helpdesk call and the administrator has engage and to revoke the VM and put the data back on.

Capital Savings. With MokaFive, enterprises have the option to implement BYOC (bring your own computer) programs for employees and contractors. Cisco and Dell made headlines last year when they initiated BYOC programs giving their employees a stipend to purchase their own computer. Both used virtualization to deliver company approved applications, but their approaches had significant limitations. In Dell's case, the only real choices was, well, Dell machines. Cisco at least allowed more latitude, so employees could purchase Macs, but "they are pretty much on their own for tech support." With these traditional desktop management models, and even with VDI, BYOC hits a snag due to online-offline access issues.

With MokaFive, IT deploys and manages the virtualized corporate environment on employee-chosen machines (Mac or a PC, online or offline) using MokaFive and benefit from the central management and distributed model I discussed above.

Going Green. There is one final area of savings I'd like to highlight -- though it may not necessarily be considered by CIOs when making a decision on desktop virtualization: the environmental impact. With MokaFive's approach, companies can use existing equipment; existing personal devices and existing corporate devices. In the case of contractors, companies are no longer buying assets, nor are they provisioning servers to the datacenter. All these add up to a reduction in new power-hungry equipment. MokaFive’s approach give you almost status-quo type of energy in the case of most work from home and contractor scenarios – and is even more effective than what we have today. I go into a lot more detail on this in an earlier post.

For our customers, the savings in all these areas have been very real. But the fact remains that desktop virtualization has over-promised and under-delivered for many years -- to the detriment of all of us. Just because two (with a third making very fast progress) very large vendors dominate virtualization, it doesn't mean innovation has ceased. It's still happening, and MokaFive is proof of it, 20+ patents and still coming.

We've really put a lot of thought into all the costs associated with managing desktops. Our customers have weighed in and helped us create a TCO model that factors in these four areas. We invite you to sign up for a personalized TCO for your environment.

Get ready. Start. Migrate.

We’ve entered the final quarter of 2010, the time when Gartner anticipates most Windows 7 migrations will start in earnest. They’ve done extensive number crunching on the costs of Windows 7 migrations, and many other analysts have further reviewed these findings and prescribed their remedy to ease the pains, if not the costs entirely.

Windows 7 migration is expensive.

No matter how one dresses it up, there’s no hiding the plain truth: IT organizations are being asked to budget an extra 20% to 60% to their costs over the next two years. In addition to the well known costs such as new hardware and Windows 7 licensing, there are many hidden costs with Windows 7 migration.

First, there is the cost of identifying which applications to migrate and when? This is a hard, time-consuming task. Even though Windows 7 is supposed to be backwards compatible, the reality is that many applications still do not work flawlessly.

Second, there is the cost of maintaining both Windows XP and Windows 7 environments for a protracted period, which can be up to two or three years for some organizations based on their migration schedule.
Lastly, there is the cost of migrating personal data. In many work environments, there has been a blurring of the personal and the corporate. Windows 7 migration brings this issue to the forefront, since IT has to decide what and what not to migrate.

There is a silver lining. Windows 7 migration also provides the best opportunity to clean up.

While the list of problems with Windows 7 migration seems endless, a migration project provides IT with the opportunity to upgrade its management architecture, enforce better data usage guidelines, and offer greater user flexibility.

The question becomes, which solution can really solve the problem? Virtualizing the desktop can significantly speed up image deployment. Gartner suggests going with a hosted virtual desktop (HVD or server hosted virtual desktop), but at the same time argues that it is expensive, and what you are saving in migration costs you are adding in capital costs.

The alternative approach (MokaFive’s approach) is to virtualize the desktop, but instead of putting it on a server, you send it back down to the endpoint for local execution, thereby eliminating the datacenter requirement. With this approach, you have no additional capital costs. You simply take your existing machines and deploy a Windows 7 virtual machine environment to them. Your users now have Windows 7 environment without having to wait for your hardware refresh cycle. The best part is that the users can still use the Windows XP on their host machine to access legacy applications.

Refresh hardware on your own timeline: Traditionally, with Windows 7, customers are left with the hard choice of either forklift-upgrading their machines or refreshing their hardware. Instead of trying to speed up the refresh, you can use MokaFive to deploy a Windows 7 LivePC on top of your existing machines until they need a hardware refresh. Even if your refresh cycle extends beyond 2014, you will be fine, since your users can be provisioned with a Windows 7 environment on their existing Windows XP machines. Then when the refresh happens on a true Windows 7 base platform, the Windows 7 LivePC can be moved in minutes.

Provide users with platform choice: With virtual desktops, you can now implement programs such as BYOC or offer employees the choice to bring in the much-desired Mac. You can leverage the migration project to get out of the device management business. Let users bring a device, and you manage the secure corporate virtual image on top of the device. Best part, unlike HVD, users are free to work online or offline.
Separate work and personal: Windows 7 migration gives the ideal opportunity to start enforcing best practices around user data. With a virtual desktop approach, users can move their personal data to the host machine, allowing you to lock down the virtual desktop.

Future-proof yourself: In IT, change often means cost and pain. But a hugely disruptive change like Windows 7 is also a golden opportunity to implement a 'future-proof' management architecture. Even if you muscle through a Windows 7 migration by 2014, what happens with the next big upgrade? By upgrading your management infrastructure to a client based virtual desktop solution, you can not only ease the next upgrade cycle but also get huge TCO benefits while at the same providing more choice to your users.

Local CPU is becoming MORE important

I caught up this week with Intel's technology evangelist, Charlie Milo, at the Intel Developer Forum, for an update on some of Intel's exciting new technologies, including accelerated 3D graphics, 3D television sets, 3D photos and cameras. One of the items that was showcased at IDF was Internet Explorer 9, which was released by Microsoft in beta yesterday.

Inevitably in our conversation, we discussed the impact of having such a browser; that is, one that renders graphics beautifully on the endpoint, on desktop virtualization. Through that discussion, it became clear that this browser will use a lot more CPU cycles to deliver the high-definition graphics and 3D images that we, the consumers, want. The question then becomes, where do you want this processing power to be executed? On an expensive server sitting in a data center, or on the endpoint?

Rendering rich 3D graphics requires a lot of power and speed, and more importantly needs to be computed close to the user for a rich, interactive experience. The data crunching can happen on the server, but in terms of rendering the graphics, it has to happen on the endpoint.

To me, these rich interactive performance applications further validate the bet we have placed on the client side, where virtual desktops are executed on the distributed resource.

How do you think the coming new browsers will impact desktop virtualization?

VMworld 2010: Great Show

It’s officially over! For us, VMworld 2010 was an exciting ride.

Day one started with a bang when Network World named MokaFive BareMetal the Hottest Virtualization Product at VMworld. Even though our booth (#1736) was in the far corner of the show floor, we had a crush of traffic visit the booth to learn more about MokaFive. There was a lot of the excitement and buzz about MokaFive especially around our recent announcements on BareMetal player, our partnership with AVG and our MSP beta program. In addition to the high volume of booth traffic, we had a great set of conversations starting with The Register in the morning, Forbes in the afternoon, and a sprinkling of industry analysts throughout the day. Then there were meetings with prospects and partners that went into the wee hours of the morning. The great food and wine at Marlowe just made it even better.

The excitement continued into day two, three and four. The session on VDI TCO caught my attention. It was truly revealing and entertaining. The speaker said, “don’t bother trying to justify VDI on the basis of TCO, find alternative justifications like security etc.” Now that is what I call clean speaking. This just reinforces my conviction that the MokaFive datacenter-less (distributed) approach is the right way to go. Among other attractions, both Brian and Gabe from brianmadden.com stopped by the booth to discuss BareMetal , we had a surprise visit by our angel investor, Vinod Khosla, and Dale did a radio gig on Internet Evolution.

Net-net the predictions I made in the previous blog turned out to be nearly correct. The messaging was cloudy and VMWare killed CVP officially. But contrary to my prediction there weren't as many open source application companies. Well two out of three, ain't bad.

It’s Official: MokaFive Goes BareMetal

Regular readers of this blog will recall that in June, we blogged about MokaFive BareMetal Player, which we were taking the wrappers off for industry insiders at BriForum. At VMworld we made our bare-metal preview official and demoed it to an appreciative audience. 

This comes, of course, at an interesting time. Just last month in its earnings call, , VMware killed its bare-metal hypervisor.  And just last week, Citrix decided to package its long-awaited XenClient bare-metal hypervisor with XenDesktop in an effort to get it to market faster.

With all the news, our bare metal solution was received as a welcome change.  The sentiment was echoed by Timothy Prickett Morgan of The Register in his eloquent (and irreverent) coverage of VMware, Citrix,  MokaFive and more.

We developed MokaFive BareMetal Player because our customers are asking for a solution that lets them forget about everything except the VM. They want to be able to run directly on the hardware and they want the same management they’re used to already with MokaFive Suite. And that’s exactly what we have with bare-metal: it provides a thin management layer that sits on the baremetal hardware, thus eliminating the cost  burden of managing additional OS’s and licenses.

Best of all, MokaFive BareMetal adheres to our commitment to deliver “choice computing.” In the bare-metal world, that means supporting a broad range of hardware—not half a handful of narrow configurations, and certainly not hardware deals cut in the backroom to lock customers in.

We believe our BareMetal will be a real game-changer in the desktop virtualization space. Like MokaFive Suite, BareMetal is designed to fit into existing infrastructure and to always be OS- and hardware-agnostic.

Take a look at this link of John Whaley’s video chat with Brian Madden at our VMworld booth. Generally, the response to BareMetal has been on par with Brian’s reaction – great! NetworkWorld even listed us as one of the hottest Vendors at VMworld.

VMworld Predictions

As I previously noted, next week’s VMworld will be MokaFive’s first showing in two years. We’re putting the finishing touches on our booth and prepping our demos. While we count down the days, I want to share some thoughts on what I predict will come out of VMworld.

1. Cloudy messaging around cloud. You don’t have to be clairvoyant to see this one. VMworld 2010 will be all about the cloud, so expect to see everyone putting out some “cloud” story—whether they have a cloud offering or not. As such, expect to sift through these myriad messages for what’s real, what’s pure marketing and what’s simply lipstick on a pig. Despite best efforts to align with the cloud story, the plain fact is that cloud is not an all or nothing model.

As an example, let’s look at desktop virtualization—which is, after all, what we know best. While server virtualization is a key component of the cloud-based delivery model, on the desktop side, the cloud discussion can take an interesting turn. Too often, the most obvious approach has been to take a desktop, virtualize it and then put it in the cloud. But, keeping in mind that cloud is not “all or nothing,” how about just centralizing the management in the cloud, but still keeping the desktop with you.

2. VMware goes back to basics. Based on recent earnings and (non) developments and news from VMware, I anticipate that it will go back to its comfort zone and core competency: the server. Like all vendors, VMware fell prey to the trends—and why not, since they have the revenue and clout. But the reality is, VMware’s business is the data center. They will refocus (or reaffirm) their server play, including server-side desktop virtualization (VDI).

3. Open source ecosystem. Expect a lot of smaller open source type plays to jockey for a position to fill into VMware ecosystem either around open source management or open source application development. They’ve seen VMware move into open source software and open source tools, so they will be want to a part to play in this.

That’s it for my predictions. The last food for thought I will leave you with is the VMware vs. Microsoft match up. VMware has openly declared war on Microsoft --but just how exactly will VMware message this at the show. I cannot wait to hear what VMware will say in its keynote.

What do you expect to see or hear at the show this year? I will be hanging around MokaFive’s booth (#1736), so would welcome your thoughts in person. This has always been one of my favorite shows, and I am excited for some real dialogue with some of the best minds out there.

Of course, we will also be demoing the MokaFive Suite, our new multi-tenancy capability and an exciting peek into a new forthcoming product that I believe will be a real game-changer. And we also will be giving away an iPad. Swing by for details.

Manage Desktops from the Cloud

Over the last two years, we’ve been helping our customers -- many of them very large brands with thousands of users -- succeed in rolling out the MokaFive Suite to their employees. Today, we’re taking the first step to make our virtual desktop management solution available to smaller companies – by enabling MSPs to offer desktop as a service with MokaFive Suite Service Provider Edition.

As part of this roll out, we’re opening up our beta program for managed service providers (MSPs) that want to offer desktop management from the cloud. Service Provider Edition includes capabilities that would allow an MSP to manage multiple customers on a single platform. As such, we’ve architected our core offering on a fully multi-tenant infrastructure, added reporting and enabled delegated management for MSPs.

This is great news for MSPs in that it can improve operational efficiencies of their desktop delivery and enable them to offer desktop management as a service at a lower overall cost. Many desktops in the world today are not managed within the enterprise, but managed by outsourced providers. This is due to the economies of scale (and skill) that can be achieved by outsourcing vendors as they pool managed desktop services across many companies.

There are other desktop management service offerings on the market, of course, but most of them have focused primarily on using the VDI-based model where both the desktop execution and management are in the cloud. As we have discussed in previous posts, that approach has inherent deficiencies such as no offline access and a poor end user experience. What we offer with the Service Provider Edition is desktop management services from the cloud, while still allowing for the virtual desktop to be executed locally and to be available online or offline.

That’s why we felt it was important to bring the power of centrally managed, locally executed MokaFive LivePCs to the channel, enabling our MSP partners to offer this technology to their customers.

MokaFive at VMworld

This year’s VMworld conference is fast approaching, and we are beginning to feel the excitement as we prepare to participate after a two-year hiatus. Over the past couple of years, we’ve been focused on three key areas: refining our product, gaining customer wins, and raising awareness of MokaFive.

First, on the product front: I am proud to say that over the last two years, the team here has built an enterprise-class product with all the capabilities, scale, security and robustness to manage enterprise endpoints.

Second, a good product translates to customer wins, and we have started to see a big ramp up in production deployments. We've spent the last two years working very closely with our customers to solve the complexities of managing desktops and enabling choice computing for end users. We’re now seeing customers who initially bought into the concept of server-based desktop virtualization saying the model is too complex and not cost effective. MokaFive’s approach of centralizing the management of virtual desktops and having them execute locally at the endpoint - irrespective of the type of endpoint - is actually gaining a lot of traction and truly validating the strategy we’ve established.

Lastly, we recently raised a round of funding this past April to add to our successes. We are now in a place where we can focus on raising awareness of the product and of MokaFive as a company. With a robust strong product and a great, referenceable customer base, I feel we can put our foot forward strongly and confidently.

As we look ahead to VMworld in less than two weeks, we’re excited about the quality of conversations we expect to have with CIOs, IT managers, sys-admins and end users about desktop virtualization.

If you are planning to attend VMworld, come by MokaFive’s booth (#1736) to see a live demo of MokaFive Suite, learn more about MokaFive’s BareMetal Player, and enter to win an iPad. You can also follow our our Twitter stream for updates before and during the show.

We look forward to participating in VMworld 2010! Stay tuned for our next VMworld blog post where I will predict the emerging themes and trends that will be discussed at the VMworld show.

VDI Project? One question to make sure you ask.

We recently hosted a CIO summit that was attended by several CIOs, representing some of the largest organizations in the US. The topic was desktop virtualization, and we had a terrific discussion about ongoing initiatives at each company.

One CIO cited a statistic that was so surprising, shocking really, it really stuck out in our minds. At their organization—one of the premier universities in the world--they’d recently evaluated the use of VDI for university employees. In their analysis, they found the all-in cost of VDI to be nearly $12K per user per year! (sound of jaws hitting floor) When contemplating the necessary server, storage and network improvements, the costs were so prohibitive they dismissed VDI as being completely impractical.

His argument was so sincere and thoughtful that other attendees were heard making mental notes to ask their staffs for a business case on their VDI projects.

If you’re considering, planning, or even deploying VDI, one piece of advice: make sure you ask this question too. If you don’t have a staff, then ask yourself. Or ask your boss. Just don’t let the question go unasked and risk a rude $12K surprise.

Overheard, five years from now: "Tell me again, why did we spend so much on VDI?"

As the story goes, during the 1960s space race, NASA was faced with a major problem. The astronauts needed a pen that could write in the gravity-free environment of space. After a $1.5 million effort, they developed the Astronaut Pen which could write in a vacuum, write with no gravity, and write in extreme temperatures. It was brilliant!

The Russians, faced with the same problem, had a simpler approach: they used a pencil.

This apocryphal tale contains a valid lesson: sometimes we spend a great deal of time, effort and money to create a “high-tech” solution, when a perfectly elegant and low cost solution is right before our eyes. (Of course, one clear alternative to VDI springs to our minds. J)

Question: how many abandoned VDI projects are littering the streets?

The CIO’s comments resonated with many of us, as we’ve heard, particularly recently, of many organizations that have investigated, piloted and ultimately abandoned VDI because the costs were so prohibitive, and because better suited alternatives do exist.

So we ask the question to all of you: how many of you have gone through this experience and ultimately decided to go with status quo or an altogether different approach?

Introducing MokaFive on BareMetal

We’re gearing up for BriForum this week, and for us, the highlight will be a sneak peak of an exciting new product that we have been working on: MokaFive BareMetal. Starting today, you can see for yourself what this solution is all about. Stop by our booth (#300) for the demo by MokaFive’s CTO, John Whaley.

The idea behind BareMetal is to provide a thin management layer that sits on the bare metal hardware. This is still in development so we don’t want to comment on the implementation details, but the benefits of BareMetal are clear: broad hardware support, extensive policy set, and the best management control in the industry.

If you’re familiar with MokaFive, you know we came out of the gate with support for VMware Player, and recently added another hypervisor to our arsenal – VirtualBox. Now, with MokaFive BareMetal, we’re going to eliminate the OS-middleman and enable users to run directly on the hardware itself.

So, why are we adding BareMetal? For one, it supports our commitment to be truly platform- and hypervisor- agnostic. Equally important, if not more, our customers have been asking for it. Those customers that are already running our Type-2 hypervisor based solution for their laptops and BYOC or employee owned devices are now looking to expand MokaFive management across all corporate desktops. With the BareMetal solution, customers will be able to use just a single Windows guest OS instead of licensing & paying for both the VM and the host OS. And the best part is that they can roll out the same virtual image, as well as policy controls, to both end users’ personal machines (using our Type-2 solution) as well as corporate-issued ones (using our BareMetal solution), with no additional management burden.

For the image, you can use the same image that you’re using for current deployments (BYOC). For installation of BareMetal, there will be a few different methods from which you can choose. Similar to other physical machines, you’ll be able to install it with installation ISOs, or over the network via a PXE server. I’m biased of course, but we have a solid solution here that dramatically simplifies management – of desktops and licenses – for customers.

If you’re at BriForum, be sure to come check out our BareMetal demo at booth #300. And while you’re there, Futurama fans should be sure to enter MokaFive’s drawing for a Bare Metal Bender.

Mac-Windows.com: "MokaFive virtual layers can rollback portions of VMs while retaining user data"

Want to know more about MokaFive's technology landscape? If so, check out the latest blog post on Mac-Windows.com—the web site for Mac-Windows integration—for more detail about virtual layers, policies, distribution, compression, and BlackBerries.

MokaFive "virtual layers" can rollback portions of VMs while retaining user data

With the layered desktop, MokaFive addresses the age old systems management problem by providing end user flexibility without compromising security. Enterprises can now reap the TCO benefits of true centralized standard image based management while enabling mass customization for their users. Unlike the classic monolithic desktop, the LivePC is separated into system, application, and user personality layers - that can be controlled and managed independently. Administrators can control and lockdown the corporate system and applications while enabling end users to customize their desktop with their own data and applications.

MokaFive 2.0 now available!

It's is a big week for the team here at MokaFive. As many of you know, MokaFive started as a project at Stanford to use virtual machines to make it easier to manage desktops. A little over a year ago we released our 1.0 product, which was a hosted solution. We got a lot of positive feedback from customers about our 1.0 product, but the number one customer request was to provide the capability to run the MokaFive service in-house.

So this week, we announced 2.0! The 2.0 technology comes in the form of an enterprise-ready Desktop-as-a-Solution platform: MokaFive Suite. With 2.0, you can install and run MokaFive Suite in your data center, behind your firewall, and serve your end-point clients without depending on us. You can integrate with all your existing management solutions. You are in total control.

Enterprise computing is reaching a turning point right now as desktop virtualization technologies mature - answering business challenges that haven't been solved before. Our customers are innovating with the quick to deploy MokaFive Suite, taking advantage of mass user-customization, policy-based security. We will share detail of how different businesses (across healthcare, legal, finance, other professional service companies) are solving their challenges - and the benefits they have achieved.

We have also added some exciting new capabilities on the client side. For a long time, we have been working behind the scenes on a new layering technology that dramatically changes the way you can deploy and manage virtual desktops. This technology allows you to separate the machine into layers that can be independently managed and updated. Among other things, you can now allow users to install their own applications, while you can still manage and update a single golden image. That's right, your users can install any applications (even kernel drivers) and they will persist across rejuvenation and updates, as long as you set the policy to allow them to do so. This is a major breakthrough and one of the biggest barriers to widespread adoption of desktop virtualization, and MokaFive is the only solution on the market today that gives you that ability.

We also re-designed the client and it is now using a new disk format. The new format is much more reliable and has better performance, especially if you are running a LivePC off of a USB flash drive that can be suddenly removed. Users running v1.x LivePCs will need to manually migrate to 2.0 to take advantage of the new features. The migration process is pretty straightforward. Export the LivePC with v1.x Creator and then import it using the v2.0 Creator. Here is a detailed document to walk you through it [link]. Let us know if you need help.

Stay in touch with the MokaFive blog for information and perspective on the concerns and trends related to the modernization of enterprise desktop computing. We invite your feedback, questions and opinions - starting with the announcement of MokaFive Suite.

Virtualization: Hype vs Reality, Part II

And we’re back with Part II of our series on what is hype and what is reality when it comes virtualization. Here is our perspective on two more topics that are getting a lot of play lately:

Reality: Virtualization is cheaper than other traditional infrastructures

Obviously a major issue for anyone in any industry right now is cost. People are looking to save money in every way they can. In light of this, many vendors in the virtualization space are chiming in about how their products and solutions can help you cut costs. Is this true? For the most part yes. BUT it’s not quite so black and white, so let’s break it down.

A desktop virtualization deployment can save you money in terms of management and support, but it can potentially be more expensive than a traditional deployment – it all depends on how it you approach it.

Right off the bat a VDI deployment costs 20-30% more from a CAPEX perspective than a traditional physical desktop deployment. However, once it’s up and running the deployment can make it much easier and cheaper to manage your IT infrastructure in the long run, *if* you do it right.

• For instance, if you go with the model of creating one image for each user, the deployment will not scale and it will end up being just as expensive to store and manage the virtual desktops as it would in a traditional physical desktop deployment, if not more expensive.


• To achieve real cost savings and make up the CAPEX expenditure, you need to leverage virtualization to make IT more scalable. What does this mean? Creating one golden image that goes out to all of your users or to large groups of users.

Hype: Remote display is the way to go

Remote display can work well, but only in very specific environments.

• Remote desktop is fast over LAN, but slow over thin pipes.


• Gigabit LAN to the server can achieve speeds nearly indistinguishable from local execution but at a much higher cost.


• Low-latency WAN connections can get acceptable performance but only if
  they are not using any graphically intensive applications.


• High-latency WAN connections are not viable for real-world usage.

Basically what it comes down to is that there are fundamental limitations to the interactive performance of applications across low bandwidth and high latency links, and we are getting close to the limit. Remote desktop just does not work well over wireless networks or on laptops.

So what do we recommend? For applications that require a high refresh rate or rich graphics, a locally executed solution is always going to offer the best performance, no matter what. Remote execution will always face speed of light limitations even with the fastest of connections.
