Microsoft Windows 7 Enterprise Application Recommendation: Desktop virtualization brings added value

Microsoft has released the Windows 7 operating system for more than two years, when this new operating system let people see a bright, concise boot screen, fresh appearance, convenient mode of operation, user-friendly settings ... Today, individual users have a deeper experience of the benefits of Windows 7 after use, and there is no doubt that the greatest improvement is performance, in addition to its good compatibility, enhanced reliability and security, faster upgrade speeds, and so on.

Although many individual users are still using Windows XP, for business people, upgrading to genuine Windows 7 will bring them a number of benefits, one of the most attractive features is desktop virtualization, which is the Windows 7 value-added value in the enterprise-wide area of the key embodiment.

When it comes to desktop virtualization, it doesn't require local, powerful and full-featured terminals, more suitable for companies that require a high degree of centralized control, or want to centrally manage a large number of it users, such as finance, telecommunications, and so on, while application virtualization gives the terminal greater flexibility for those who need more flexible local processing capabilities, But also want to ensure the application of data security users, such as the company's senior and mobile workers, small and medium-sized users. This type of user's computer itself can also completely receive the virtual desktop (that is, desktop virtualization must include the application of virtualization, but the application of virtualization does not require the desktop is virtual), thus for the enterprise IT executives to build for different users of the application and management model to provide greater convenience. The ultimate goal of desktop virtualization is to make the IT architecture of your enterprise more secure, efficient, and manageable.

Desktop Virtualization diagram, we can break their computer into three levels, the hardware layer is the local computer, and the desktop layer is the operating system, application layer is the application software, if the desktop is not local, is the virtual desktop, the application is not installed locally, is the application of virtualization. Note the relationship between desktop virtualization and Application Virtualization, although application Virtualization is part of desktop virtualization, but it can be used alone. When we deploy desktop virtualization and deploy desktop and application to the background, you will find that the existing hardware is more than just a role to display input and I/O input, thus significantly reducing the need for hardware performance, which is clearly beneficial to reducing terminal costs

If desktop virtualization has far-reaching implications for both users and developers, migration to Windows 7 is certainly a catalyst. Desktop virtualization Technology in the Microsoft Windows 7 operating system focuses on data, applications, and Windows configurations, allowing users to access their data at work or at home.

Virtual Desktop Infrastructure (VDI) is an architectural pattern in which customer operating systems are run in a server-based virtual machine environment and are connected to users through the network to interact

Microsoft's VDI infrastructure, the background is Hyper-V based server virtual platform, used to provide virtual machines, and the front-end PC or thin client more simply for desktop rendering

The advantages of VDI are mainly three: reducing TCO, ease of management, and increased office flexibility

With desktop virtualization technology in Windows 7, you can reduce total cost of ownership (TCO), and client PC management and terminal configuration will be more efficient and flexible. In fact, the customer's PC may not be given by the enterprise, personal purchase of PCs in the enterprise application environment, will bring many uncertainties and insecurity, and if the office environment is unified in the Desktop virtualization architecture, the management of equipment to the management of the account, it is much simpler.

After the deployment of desktop virtualization, in addition to the enterprise's IT hardware architecture and environment changes, but also to the day-to-day business model of the enterprise change. Many companies in addition to formal staff, there are temporary and hourly workers, in the past, the office environment, these personnel mobility of the enterprise IT system configuration poses a greater challenge, and the use of desktop virtualization, you can flexibly deploy new desktop image to these mobile staff. In addition, when employees outside the office, desktop virtualization can also make the data node single, outside staff as long as the network can access the enterprise internal data, so also make the staff's work location more flexible and diverse.

We can imagine that as long as there is a certain rate of bandwidth connectivity, you can seamlessly connect to the company's virtual desktop environment, then the company's branches can enjoy the headquarters of the virtual desktop environment, employees can even achieve home-office ideal. Moreover, because the data are stored in the company's data center, does not exist in the terminal (including PCs, notebooks), so the problem of leakage of data has been well contained, which is good for the safety management of enterprises.

Desktop virtualization utilizes technology and architecture similar to Remote Desktop and Terminal Services, where client PCs and thin clients use the Remote Desktop Protocol (rdp,remote Desktop Kyoto), where the desktop runs on a server in the background, and the front end is used only to render desktop images. RDP is an important design concept for Windows 7 that allows 3D rendering to be done either on the local computer or on a remote desktop computer, and RDP can make full use and compression of network bandwidth, thereby reducing network overhead. Currently, Windows 7 uses RDP 7.0, which leverages the client's GPU capabilities to support Aero Glass UI and video playback.

Windows 7 Service Pack 1 uses the latest RDP, which offers many benefits for RDP client rendering and host-side rendering

Microsoft is about to launch its Windows 7 Service Pack 1 next year, further enhancing desktop virtualization, adding remote access platform RemoteFX, allowing virtual desktops and application users to receive rich three-dimensional and multimedia experience while accessing information remotely.

RemoteFX is not a new stand-alone product of Microsoft. Instead, it contains a series of RDP technologies that highlight graphic virtualization and use advanced coding. RemoteFX can be said to be a "secret weapon" in Microsoft's Remote Desktop server, allowing users to gain a high quality experience by connecting to their virtual desktops and applications over the network. With Microsoft RemoteFX, users can work remotely in Windows Aero desktop environments, watch Full-screen video, run 3D applications, and so on, all of which are close to the local performance of connecting to a LAN. Users can use RemoteFX to access their work environment through standard RDP connections that include PCs, thin clients, and low-cost client devices. RemoteFX technology can be applied not only to common remote desktops, such as RDP, Terminal Services, but also to virtualized environments such as Hyper-V.

RemoteFX in Windows 7 will implement a near-local rich media experience with a session based or virtual desktop

The structure of the various components of Hyper-V VDI and RemoteFX

RemoteFX, like the virtual desktop you use, uses DirectX to present applications that are not available on a virtual desktop, and that future Web sites can take advantage of Flash and Silverlight, which are also necessary to deal with the future market expansion of VDI.

The value of RemoteFX is embodied in the realization of technology and delivery of customer value

All in all, Windows 7 will continue to play its unique advantage and role in the enterprise-class arena, accelerating the pace of mainstreaming into virtual desktops. At the same time, as Microsoft continues to strengthen the virtual desktop features and user experience of Windows 7, business people's day-to-day office will be more efficient and convenient, while increasing productivity and creating higher value for the enterprise.
