Windows 8: A Summary and Some Points of View

Each new version of Windows for Microsoft brings new challenges, which are more or less well identified.

Microsoft Windows 8 is thus forced to meet a demanding timetable and therefore limit the range of developments that could cause widespread disruption, while providing an operating system to meet two challenges:

- One is strategically and commercially very limited in the short term, taking into account the level of PC of different forms of virtualization.
- The other is more tactical but commercially important in the short and medium term: to provide a credible alternative to Apple and Google Android IOS on the market shelves (or slate), whose popularity among the general public could be extended in companies.
8 Windows and virtualization
Windows 8 will include a hypervisor (Hyper-V v3.0) which will natively run different operating systems on a workstation. Like what is currently offered by Microsoft Windows Server 2008 R2.
We will not detail the improvements made in version 3 of Hyper-V will be integrated into Windows 8 (this is discussed in the news section of the same letter Calipia), the main addition for server virtualization with such opportunities for multi-session travel hot – without interruption to the user – of virtual machines (with Live Migration) hot or moving VMs between different storage spaces (with the Live Storage Move).
That said, some new features in Hyper-V v3.0 is interesting for workstations, such as Hot reallocated RAM to a virtual machine, network communication possible between two virtual machines via a WiFi network or the graphic optimization RemoteFX 8 on Windows to access a virtual machine with Remote Desktop Connection (RDC).
The ability to enable Hyper-V on Windows 8 will only be possible for computers equipped with 64-bit processors (x64, as with Windows Server) and supporting the role of Second Level Address Translation (SLAT), which manages two levels of mapping physical and virtual memory addresses, providing significant gains in performance in a virtualized environment. And of course this possibility is unlikely given that the eight editions of Windows to businesses (and the equivalent of the Ultimate), but it is too early to be assertive, Microsoft have not yet reported on practical aspects of marketing of its future operating system.
These practical issues are discussed the arrival of virtualization on the desktop with Windows 8 brings some thoughts as follows:
- With the integration of its technology Hyper-V v3.0 in Windows 8, Microsoft is on the desktop at once hard enough to rival VMWare and to a lesser extent his “partner” Citrix, giving a significant boost (if Windows knows the expected success 8) to its file format virtualized hard drives, which could significantly change the situation in a market currently dominated by VMware.
- The previous Microsoft virtualization technology for desktop was Virtual PC Virtual PC and Windows (Windows 7). What about the support of this technology certainly outdated but still used by individuals who opted for Windows XP mode (to run incompatible applications on Windows 7) or companies who have chosen, for the same reasons to deploy the component MED-V (Microsoft Enterprise Desktop Virtualization) included in the Microsoft Desktop Optimization Pack (MDOP)? A small redesign of these components is therefore …
- Most importantly, Microsoft has filed a patent in August on the possibility of getting the operating system in an isolation mode (sandbox / sandbox / not bother me / etc.) Which means that applications are executed virtually. And no communication on the availability of this specific technology called Windows Live Experience (probably after hours of meetings between the marketers would do better to spend time with their children), one can legitimately ask the question of the link with offer application virtualization APP-V also proposed through the MDOP.
This integration of hardware virtualization in the Windows operating system 8 raises the question of potential duplication of infrastructure and APP MED-V-V for companies that made these components and having a fleet Windows Vista, Windows 7 and Windows 8 …
