With server-hosted virtual desktops (VDI), you take something that used to be a few centimeters from someone's fingertips - their Windows desktop - and move it sometimes thousands of miles away, and you expect them to be okay with that. It’s possible, but choose your technology vendor wisely, because the project’s success will hinge on the end user experience.
It’s not easy to give users an equal or better Windows desktop experience with VDI than they have with their local PC. If they rely on videoconferencing to collaborate with their colleagues, the VDI system has to work with their local webcam and it has to handle the video stream properly so they don’t get choppy voice and video. If they use a tablet, your VDI vendor’s tablet client has to be good, with intuitive touch gestures. There may need to be a way for them to install software, and they may need to use the system over a 4G/LTE network link while traveling.
To do all of these things and more across a wide range of work styles, devices, applications and networks requires sophisticated, expensive capabilities. If you choose your vendor primarily on cost, the solution you get may not have what you need to deliver an acceptable user experience - especially if your business needs change.
Intel has made no secret of its development of the Xeon D, an SOC product designed to take Xeon processing close to power levels and product niches currently occupied by its lower-power and lower performance Atom line, and where emerging competition from ARM is more viable.
The new Xeon D-1500 is clear evidence that Intel “gets it” as far as platforms for hyperscale computing and other throughput per Watt and density-sensitive workloads, both in the enterprise and in the cloud are concerned. The D1500 breaks new ground in several areas:
It is the first Xeon SOC, combining 4 or 8 Xeon cores with embedded I/O including SATA, PCIe and multiple 10 nd 1 Gb Ethernet ports.
It is the first of Intel’s 14 nm server chips expected to be introduced this year. This expected process shrink will also deliver a further performance and performance per Watt across the entire line of entry through mid-range server parts this year.
Why is this significant?
With the D-1500, Intel effectively draws a very deep line in the sand for emerging ARM technology as well as for AMD. The D1500, with 20W – 45W power, delivers the lower end of Xeon performance at power and density levels previously associated with Atom, and close enough to what is expected from the newer generation of higher performance ARM chips to once again call into question the viability of ARM on a pure performance and efficiency basis. While ARM implementations with embedded accelerators such as DSPs may still be attractive in selected workloads, the availability of a mainstream x86 option at these power levels may blunt the pace of ARM design wins both for general-purpose servers as well as embedded designs, notably for storage systems.
Previously Microsoft tried to discourage customers from using virtual desktop infrastructure (VDI) on top of rival operating systems by applying complex licensing rules involving various TLAs such as RUR, VDA and CSL (which I’m not going to explain here, because they are, thankfully, no longer needed). The USL is far simpler - clear Windows licensing replacing translucent frosted glass, so to speak.
I’ve recently been thinking a lot about application-specific workloads and architectures (Optimize Scalalable Workload-Specific Infrastructure for Customer Experiences), and it got me to thinking about the extremes of the server spectrum – the very small and the very large as they apply to x86 servers. The range, and the variation in intended workloads is pretty spectacular as we diverge from the mean, which for the enterprise means a 2-socket Xeon server, usually in 1U or 2U form factors.
At the bottom, we find really tiny embedded servers, some with very non-traditional packaging. My favorite is probably the technology from Arnouse digital technology, a small boutique that produces computers primarily for military and industrial ruggedized environments.
Slightly bigger than a credit card, their BioDigital server is a rugged embedded server with up to 8 GB of RAM and 128 GB SSD and a very low power footprint. Based on an Atom-class CPU, thus is clearly not the choice for most workloads, but it is an exemplar of what happens when the workload is in a hostile environment and the computer maybe needs to be part of a man-carried or vehicle-mounted portable tactical or field system. While its creators are testing the waters for acceptance as a compute cluster with up to 4000 of them mounted in a standard rack, it’s likely that these will remain a niche product for applications requiring the intersection of small size, extreme ruggedness and complete x86 compatibility, which includes a wide range of applications from military to portable desktop modules.
Bill Gates said "People everywhere love Windows.” Whether or not you agree, the fact that Microsoft Windows remains the de facto standard for business productivity after nearly 3 decades, suggests that many still do. But as the sales figures of Microsoft’s competitors suggest, people everywhere love lots of other things too. And one of the reasons they love them so much is that they like to get things done, and sometimes that means getting away from the office to a quiet place, or using a technology that isn’t constrained by corporate policies and controls, so they can be freer to experiment, grow their skills and develop their ideas uninhibited.
Technology managers I speak with are aware of this, but they’re justifiably paranoid about security, costs, and complexity. So the result of these conflicting forces coming together is inspiring rapid innovation in a mosaic of technologies that Forrester collectively calls digital workspace delivery systems. It involves many vendors, including Microsoft, Citrix, VMware, Dell, nComputing, Amazon Web Services, Fujitsu, AppSense, Moka5, and more. The goal of our work is to help companies develop their capabilities for delivering satisfying Microsoft Windows desktop and application experiences to a wide range of users, devices, and locations.
When I was maybe 2 years old, my mother lost track of me in a Toys-R-Us store. After a dozen stressful minutes, she finally found me - holding a Fisher-Price airplane. And so began my love affair with airplanes and aviation. So as I looked through the break-out schedule while attending NVIDIA’s GPU conference two weeks ago in San Jose, California, Gulfstream Aero’s session on transforming manufacturing and field service with desktop virtualization caught my eye. It didn’t disappoint.
There are 2 reasons why I liked this session so much and why I think it’s worth sharing with you:
It’s a nice example of technology that makes the work easier for employees, and helps them improve the customer experience directly.
It’s also an example of how a technology that’s not necessarily a money saver (in this case, VDI) shines when it enables workers do something that would be difficult or impossible any other way.
This week, IBM announced its new line of x86 servers, and included among the usual incremental product improvements is a performance game-changer called eXFlash. eXFlash is the first commercially available implantation of the MCS architecture announced last year by Diablo Technologies. The MCS architecture, and IBM’s eXFlash offering in particular, allows flash memory to be embedded on the system as close to the CPU as main memory, with latencies substantially lower than any other available flash options, offering better performance at a lower solution cost than other embedded flash solutions. Key aspects of the announcement include:
■ Flash DIMMs offer scalable high performance. Write latency (a critical metric) for IBM eXFlash will be in the 5 to 10 microsecond range, whereas best-of-breed competing mezzanine card and PCIe flash can only offer 15 to 20 microseconds (and external flash storage is slower still). Additionally, since the DIMMs are directly attached to the memory controller, flash I/O does not compete with other I/O on the system I/O hub and PCIe subsystem, improving overall system performance for heavily-loaded systems. Additional benefits include linear performance scalability as the number of DIMMs increase and optional built-in hardware mirroring of DIMM pairs.
■ eXFlash DIMMs are compatible with current software. Part of the magic of MCS flash is that it appears to the OS as a standard block-mode device, so all existing block-mode software will work, including applications, caching and tiering or general storage management software. For IBM users, compatibility with IBM’s storage management and FlashCache Storage Accelerator solutions is guaranteed. Other vendors will face zero to low effort in qualifying their solutions.
This morning Citrix announced the acquisition application mobilization vendor Framehawk for an undisclosed sum as the battle for high performance for corporate Windows apps on mobile devices rages on. Here’s my take:
It's a good acquisition for Citrix and in turn for I&O pros for 3 reasons:
Some of Framehawk's technology will be additive to Citrix's enterprise portfolio. Specifically, Framehawk's framebuffering protocol - called Lightweight Framebuffer Protocol, or LFP - is designed for mobile carrier networks like 4G/LTE where there is often highly variable latency, loss, and jitter. Citrix will add it to their arsenal alongside HDX to improve the end user experience of server-hosted Windows applications on mobile devices for XenDeskop App Edition and XenDesktop.
It will be a boon for DaaS providers' customer experience. Citrix is in the business of building a Desktops-as-a-Service (DaaS) platforms for service providers. One of the barriers to the success of DaaS in the enterprise, and a potential source of value for service providers, is the user experience on mobile devices over mobile networks. Another player to watch the remote desktop/app protocol space for mobile networks is RapidScale.
It's a competitive take-out play as well. Delivering Windows apps from the datacenter to both corporate and employee-owned desktops, laptops and mobile devices is what Citrix does - it's their place in the technology universe. Framehawk's technology approach, while expensive, has some advantages. Citrix was probably starting to see them in more deals as competition.
In Barcelona this week, VMware announced that it is acquiring Desktops-as-a-Service provider, Desktone. This is a market I've been watching for several years, and I think this is good news for both Desktone and VMware customers. On one hand it provides an alternative for VMware prospects who are unsure whether they want to make the investment in ramping up an in-house VDI initiative, and it provides a scale-out option for existing VMware View customers who may be loathe to make additional capital investments to expand their capacity. With Citrix also developing their own homegrown DaaS infrastructure offering for service providers, this move further legitimizes the DaaS market.
Forrester has been tracking the rise in interest in DaaS specifically in our Forrsights surveys of IT decision makers for the past 2 years, which gives us a unique view into the market. In Figure 1 below, we can see the rise in IT decision-maker interest in DaaS relative to on-premise hosted virtual desktops, and see that year-over-year growth of DaaS interest is strong. The market accelerated in part because Infrastructure-as-a-Service providers see it as a way to monetize their existing infrastructure investments.
Winning teams delight in the 'doing', not the 'winning'
When I was growing up in Pittsburgh, Pennsylvania, Chuck Noll was the head coach of the Pittsburgh Steelers, and his leadership was my first glimpse into what separates teams that win from teams that don't. My favorite quote from Noll exemplifies his view both simply and eloquently: "The thrill isn't in the winning, it's in the doing." What Noll taught his players, including Terry Bradshaw, 'Mean Joe' Green, and Franco Harris, is how to delight in the joy of doing, over the joy of winning. Why? Because the 'winning' won't come unless your passion comes from the 'doing'!
This is why I'm so excited about the explosive trend of BYOD and consumerization of IT on so many levels, from cloud computing to tablets. Workers are putting the joy back into the 'doing' parts of their jobs by exploring different ways of working, and using technologies that often exceed what even the best IT organizations can generally provide. It's also why I think we'll see a rebound of Hosted Virtual Desktops (also known as VDI) through 2013 and beyond. But first, let's look at the data:
IT interest in VDI appears to be on a downward trend
Forrester's annual survey of IT decision-makers revealed a drop in interest and plans for VDI initiatives from 2011 to 2012:
But a shift in the IT drivers for VDI suggests it could actually be an inflection point
