Desktop Virtualization (i) Vision and reality

Today's end-user computing has come to a revolutionary era, with a common vision of how you can access your applications and data whenever and wherever you use it. Can desktop virtualization make us a step closer to this vision?

I've been focusing on desktop virtualization since the end of 2008. There are also four or five desktop virtualization projects that are directly involved in the next few years. Although a lot of media analysis every year is noisy this is the general trend, but did not see large-scale popularization. To think carefully, many of the user's concerns are also understandable. This article takes you to analyze some of the user's concerns to explore some possible solutions.

A large investment in the early stage

Whether the user wants to have a project, input and proceeds this account must be counted. Server virtualization, the benefit is obvious, the investment income than even I buy vegetables are not clear money also see plainly. Desktop virtualization to save costs This card is not good to make.

Hardware input

Data center facilities, servers, networks, and storage a little. In particular, desktop virtualization is a high requirement for storage. Items that fail frequently are folded onto the store. For example, take a virtual desktop 30 ioPS example, 3,000 virtual desktop is 90,000iops. Storage devices that support this IOPS demand are not cheap. Network bandwidth, latency and security also need to meet the needs, in some cases need to buy network optimization equipment, load balancing equipment, security access control, expand bandwidth and so on. There is also the cost of thin terminals and so on.

Software input

In addition to desktop virtualization software, Microsoft's licensing costs are not low. Would someone not understand that I already have permission to use Windows? This refers to the license VDA that accesses the terminal equipment used by the virtual desktop. Microsoft's license to desktop virtualization is complex, not the focus of this article. Especially want to provide Desktopas a service service provider more to Shipi careful.

Human resources: Design and implementation of the complexity of the requirements of a strong ability to take this job, have the ability to not cheap, this manpower cost is a piece.

Recommendation: Compared to traditional storage scenarios, there are a number of emerging storage solutions that can significantly reduce the storage costs required to implement desktop storage. For example, distributed storage solutions, pluggable SSD to reduce storage array IOPS requirements, storage tiering and so on, master image optimization can greatly reduce IOPS, in some cases, network optimization equipment can greatly reduce the demand for bandwidth;

Two management is not simple

Is it bob to move the desktop from the local to the data center? Management can be a bit sloppy. First of all, how do you manage Master Image? How to ensure timely updates can also not affect users? Second, how do you let virtual desktop users use applications? Is it appvirtualization? Xen App? or pre-installed in Masterimage. Often desktop virtualization is a large enterprise, which is necessarily a physical desktop and virtual desktop coexistence environment, you are adopting a consistent strategy, or the individual management?

Suggestions:

It is best to have a holistic view of the physical PC and the Virtual PC in management. Although the same scheme is not necessarily used entirely. But it's best to be forward-looking. When the technology matures, the physical environment and the management of the virtual environment can be integrated together.

Desktop is not an end, the application is the user's real concern. How to install and manage applications, preferably with a strategic consideration. For example, some enterprises take applicationvirtualization as the first strategic consideration

Be cautious about expansion. The expansion of the desktop virtualization system is not as simple as adding hardware, which can cause bottlenecks somewhere. Need to have a perfect capacityplanning and reporting system, let the manager know that the current hardware can support the maximum number of users, if more than the current design capacity of the new user words, need to invest how much.

Three users are not satisfied

We have used windows for nearly 20 years and have formed our user habits. We have personality settings, we can install software, we want to enjoy video audio, we want multiple large screen, network printing and so on. These are not problems on the physical desktop, and now the most basic hardware can meet the needs of most people. But after desktop virtualization, how much computing and network resources can you have on a virtual desktop? Users regardless of your set, expectations will not be reduced, the virtual desktop How to achieve expectations is a small challenge.

Suggestions:

In the project verification phase of the user needs to be thoroughly digested. A large enterprise often has a variety of different user groups, its focus is also different. Virtualization scenarios need to be tailored to different user groups, rather than across. Persistentdesktop, Pooled Desktop, published Desktop and so on have their own suitable user groups.

GPU virtualization can be considered when the application of graphics processing ability is high. This avoids consuming a lot of CPU resources for graphics processing.

In user personalization, many vendors have a plan for user profile management. In recent years, the concept of user environmentvirtualization has been put forward.

In addition to special environments such as call center, most users want to have permission to install the software themselves, which needs to be considered in terms of authority management.

Summary

The above recommendations only address the user's concerns to explore some possible ways. I never thought a scheme was right for all situations. Desktop virtualization is no exception. But as technology and markets mature, it may be possible to see more users actually realize the range of changes that desktop virtualization brings. such as BYOD, anytime, anywhere access and so on.

The wonderful is only just beginning.
