Wyse has launched a virtual desktop accelerator and hopes that will open the door to greater acceptance of the concept of a hosted virtual desktop environment. One of the key inhibitors in the past have been overall performance due to transmission latency and loss of data that required retransmission. Wyse, among others, has targeted this issue with its new product.
Here's what Wyse has to say about it:
Wyse Technology, the global leader in thin computing and client virtualization, today announced that it will launch a new software product, Wyse Virtual Desktop Accelerator (VDA). Wyse VDA addresses limitations of existing data centers, which are currently constrained by proximity. Today, an application or service, hosted and delivered from data centers is typically within 100-300 miles of the end-user recipient. Without this proximity, the user experience suffers from network latency, packet loss and other inefficiencies found in longer networks. Because of these issues, businesses are forced to maintain multiple data centers to handle all geographies. Wyse VDA virtually eliminates these geographic constraints by accelerating network protocols up to three times in order to greatly enhance remote end-user productivity and experience in virtualized settings.
Enterprises are able to consolidate data centers, eliminate redundancies, improve ease of management for the IT staff, and significantly reduce overall maintenance costs. The software-only solution is also easy to deploy, requires no hardware or appliances, and is optimized for virtual desktop deployments. The reduction in data center usage also has Green IT implications, as energy consumption and carbon emissions will also be significantly minimized.
Wyse Virtual Desktop Accelerator will accelerate popular virtualization architectures such as Citrix® XenApp™, Citrix® XenDesktop™, VMware View and Microsoft Terminal Services.
Wyse VDA addresses challenges faced by companies attempting to use cloud computing or virtual clients located around the globe but find the user experience unacceptable due to network distance. Working without specialized hardware, Wyse VDA complements existing remote desktop protocols, including Citrix® ICA®, Microsoft RDP, and VMware View ,accelerating the experience to LAN-delivered levels. By reducing the impact of network latency, Wyse VDA eliminates the sluggish performance often associated with virtual desktops connected to remote data centers or public clouds. Remote users will, for the first time, experience the same level of network quality as local users.
These benefits also extend to local geographies, whether end users are located only a few miles from a data center, are in the next state or the next country. Latency and packet loss inefficiencies are mitigated without any impact on end user experience.
Wyse VDA also can help enterprises with business continuity and in disaster recovery scenarios. In standard operation scenarios, end users are located close to the data center. With Wyse VDA, if those data centers are in a disaster situation, the enterprise can easily connect the effected end users into alternate data centers without compromising their experience.
Wyse VDA does not interfere with the security and encryption of the underlying remote display protocols. Wyse VDA works standalone or as a compliment to existing hardware WAN accelerator solutions adding value to customer deployments by providing acceleration specific to remote desktop protocols.
Available built-in to Wyse ThinOS 6.4 devices and select Wyse thin clients, and for PCs running the Microsoft Windows XP Pro operating system, Wyse Virtual Desktop Accelerator will be generally available July 8th.

Desktop virtualization, regardless of its form, has not gained the momentum that its cousin, server virtualization, has enjoyed. This may be because it is somewhat easier to deal with a smaller number of systems all housed in organizational datacenters than with machines that are distributed throughout the organization. A long list of companies, including Citrix, ClearCube, HP, Pano Logic, Virtual Computer, VMware, Wyse and others, have addressed this issue and yet, server virtualization is still the area of highest interest in most of the end user organizations I've visited.
I believe that this could be attributed to the fact that a person's desktop system is not viewed as a company-owned tool by many who use these systems on a daily basis. They are seen as personal tools, and individuals have a strong sense of ownership.
Local desktop virtualization, that is the ability to execute encapsulated workloads on one's own local system has gotten more attention than remotely hosted workloads for a number of reasons including the fact that individuals can still cling to the belief that the system is "theirs."
Wyse's announcement doesn't really address that issue although it appears to offer a great deal of value for those embarking on the journey to move virtual desktops to their own datacenters or, perhaps, are taking the first initial steps to move workloads into the clouds.
Unasked for shoot-from-the-hip advice
Wyse, you have products that address a number of the issues inhibiting the growth of desktop virtualiztion. It might be a good idea to focus a bit more attention on helping individuals understand that they're not giving up control by allowing some or all of the applications they use to be move either into the organization's own datacenters or into the datacenter of some hosting or managed services supplier.
If you can show that the experience these individuals will have is identical to that of having their own system, the level of resistance will be much lower.
