Desktop Virtualisation – Fact or Fiction?


Published on

The very term “Desktop Virtualisation” has become a source of controversy, with multiple technologies all claiming to be the breakthrough solution that will change the way we manage and deploy our desktops. This session compares the multitude of approaches, their costs, the myths, the FUD and what it all means.

  • vWorkspace delivers five levels of independence enabling organizations to deliver desktops and applications with the most cost-effective combination of virtualization technologies for the needs of each category of users.Reduce storage costs with choice across Microsoft, NetApp, and VMware technologiesGain flexibility for VDI across multiple platforms – run simultaneously or use to evaluate other platforms in the future without a rip and replace expenseDeliver the most cost effective desktop and application delivery type across multiple technologies - Mix and match (VDI, TS, Blade PCs) to provide dynamic and location-independent access for usersDrive employee adoption with an optimized user experience - have freedom to choose from multiple protocols to help deliver a quality end-user experienceSupport for a host of access devices including Windows, Mac, Linux, and Java, as well as support for thin clients from leading manufacturers including HP, Wyse, IGEL, 10zig and thinspacevWorkspace is about providing a customizable solution to meet your needs today and in the future!
  • The following is a collection of tools and assets to help you identify, position, and sell Quest vWorkspace. Many of these are available via PartnerZone (have no idea if this is true or not…should be )

    3. 3. Server virtualization worked out great, why not desktops?<br />Because VMware invented it, right?<br />Hardware consolidation<br />Ease of management<br />Fault tolerance<br />Because desktop management is hard<br />Windows is cheap because it's an open platform = cheap hardware, but millions of device drivers = Low CapEx, high OpEx<br />Security and Offshoring<br />Data cannot leave my network, but the presentation of that data can<br />Greater client device choice, including thin clients<br />Remote Access<br />Desktop Virtualization – Why?<br />
    4. 4. Hosted "partial virtualization“<br />Hosted full desktop virtualization<br />Client-side/distributed partial virtualization<br />Client-side/distributed full desktop virtualization<br />Also worth mentioning: Application Virtualization<br />Desktop Virtualization Types (1)<br />
    5. 5. Hosted "partial virtualization“<br />Terminal Server/Session Host<br />Back to the future! This is where it all began<br />“Remote presentation”, “Windows mainframe” …<br />“Slice” of a Windows server, remote presentation, thin client<br />Sometimes treated as an application virtualization tool, but can provide a full desktop too (see next slides)<br />Lack of personalization: Profile can be personalized just fine, but no user-installed apps. Do you want them anyway?<br />Parallels Virtuozzo<br />Shared Windows Server, but with greater session isolation than Session Host<br />Popular with MSPs for virtualizing Linux workloads – gaining some early traction for virtualizing Windows too<br />Desktop Virtualization Types (2)<br />
    6. 6. Operating System One<br />
    7. 7. Operating System Two<br />
    8. 8. Operating System Quiz<br />Windows Server 2008 R2 Remote Desktop (RDSH)<br />Windows 7 Desktop or<br />Virtual Desktop (VDI)<br />Operating System <br />One<br />Operating System <br />Two<br />Windows RDSH has > 5x the scalability over VDI<br />
    9. 9. Hosted full desktop virtualization<br />Windows XP or 7 images on a server hypervisor (ESX/ESXi/Hyper-V/Xen/KVM)<br />Rapid, automated provisioning of virtual desktops in datacenter<br />Remote access = wide choice of access devices<br />4x cost compared to Terminal Server/Session Host!<br />Massive forecasts from Gartner, Goldman Sachs et al<br />Don’t assume you have to do it the same way as server virtualization<br />Local storage vs. network storage<br />Personal vs. Pooled Desktops<br />Do you need VMotion/Live Migration?<br />Desktop Virtualization Types (3)<br />

Laptops for travelers</li></li></ul><li>Client-side/distributed partial virtualization<br />Redirects local OS to provide central management and control<br />No hypervisor<br />Performance should be roughly same as physical desktop<br />Vendors include: Wanova, AppSense, Ringcube<br />Only solves part of problem of desktop management?<br />OS deployment<br />Badly behaved apps<br />Patches and updates<br />Security<br />Desktop Virtualization Types (4)<br />
    22. 22. Client-side/distributed full desktop virtualization<br />Vendors include: MokaFive, Virtual Computer, XenClient, Virtual PC, Windows 7 “XP mode”, MED-V<br />Well-suited to “offline” or intermittently-connected users<br />Some solutions that sync the entire disk image with a hosted VM in the datacenter = big $$$<br />Other solutions rely on apps to sync user data and leave the VM on the laptop<br />Type 1 vs Type 2 – a religious debate! Table on next slide:<br />Desktop Virtualization Types (5)<br />
    23. 23. Type 1 vs Type 2 Client Hypervisors<br />
    24. 24. For hosted virtualization types, the user experience is determined by the display protocol<br />1) Intelligent client protocols<br />Microsoft RDP, Quest EOP (for RDP), Citrix ICA/HDX<br />Uses client resources to draw graphics and play multimedia<br />Better server scalability<br />Works on WAN/VPN/Internet<br />Multimedia apps need to be supported individually<br />2) Bitmap remoting<br />Teradici PCoIP, Microsoft RemoteFX, Red Hat SPICE?, HP RGS?<br />Bitmap remoting allows for simpler, cheaper clients but requires more server resources and network bandwidth<br />Automatically supports all apps<br />Display Protocols<br />
    25. 25. Possibilities:<br />Full-screen Flash with EOP Multimedia Acceleration over WANif connectivity allows<br />Effect of EOP GA on animation<br />Effect of EOP Xtream on latent connections<br />Short Demo<br />
    26. 26. There is no silver bullet. Even organizations who say they are going 100% VDI have other solutions for laptop users, power users, Macs, executives, etc...<br />Recommendation: Break users into classes and assign the most appropriate tech. VDI is *expensive* and so use lower cost alternatives wherever possible to lower the average cost<br />Don’t P2V existing desktops. You need a fresh start! For VDI to be affordable you need to restrict users, and get rid of wasted storage<br />Let’s look at some case studies<br />So What Do I Do?<br />
