Desktop Virtualization – Fact or Fiction?

Agenda

• Server virtualization worked out great, why not desktops?– Because VMware invented it, right?– Hardware consolidation– Ease of management– Fault tolerance

• Because desktop management is hard– Windows is cheap because it's an open platform = cheap

hardware, but millions of device drivers = Low CapEx, high OpEx

• Security and Offshoring– Data cannot leave my network, but the presentation of that

data can

• Greater client device choice, including thin clients• Remote Access

Desktop Virtualization – Why?

• Hosted "partial virtualization“• Hosted full desktop virtualization• Client-side/distributed partial virtualization• Client-side/distributed full desktop virtualization• Also worth mentioning: Application Virtualization

Desktop Virtualization Types (1)

• Hosted "partial virtualization“• Terminal Server/Session Host

– Back to the future! This is where it all began– “Remote presentation”, “Windows mainframe” …– “Slice” of a Windows server, remote presentation, thin

client– Sometimes treated as an application virtualization tool, but

can provide a full desktop too (see next slides)– Lack of personalization: Profile can be personalized just

fine, but no user-installed apps. Do you want them anyway?

• Parallels Virtuozzo– Shared Windows Server, but with greater session isolation

than Session Host– Popular with MSPs for virtualizing Linux workloads – gaining

some early traction for virtualizing Windows too

• Hosted full desktop virtualization• Windows XP or 7 images on a server hypervisor

(ESX/ESXi/Hyper-V/Xen/KVM)• Rapid, automated provisioning of virtual desktops in

datacenter• Remote access = wide choice of access devices• 4x cost compared to Terminal Server/Session Host!• Massive forecasts from Gartner, Goldman Sachs et al• Don’t assume you have to do it the same way as

server virtualization– Local storage vs. network storage– Personal vs. Pooled Desktops– Do you need VMotion/Live Migration?

Desktop Virtualization Types (3)

Annual per user costs Physical Desktop VDI (HVD) Terminal Server

Hardware costs $340 $300 $110

Software costs $100 $200 $170

IT Operations $600 $400 $260

Total $1040 $900 $540

Desktop Virtualization Types Compared

• Select the appropriate technology for each class of user:

Knowledge Workers

VDI

Power Users

Physical PCs

• Fast and personal

• Provisioned on-demand

• Fully isolated and secure

• Standard desktop OS

Task Workers

Terminal Server

• Shared OS and Apps

• Server OS

• High user density

• Low licensing costs

• Fast and powerful

• Unlimited graphics experience

• Demanding users/applications

• Laptops for travelers

• Client-side/distributed partial virtualization– Redirects local OS to provide central management and

control– No hypervisor– Performance should be roughly same as physical desktop

• Vendors include: Wanova, AppSense, Ringcube• Only solves part of problem of desktop

management?– OS deployment– Badly behaved apps– Patches and updates– Security

Desktop Virtualization Types (4)

• Client-side/distributed full desktop virtualization

• Vendors include: MokaFive, Virtual Computer, XenClient, Virtual PC, Windows 7 “XP mode”, MED-V

• Well-suited to “offline” or intermittently-connected users

• Some solutions that sync the entire disk image with a hosted VM in the datacenter = big $$$

• Other solutions rely on apps to sync user data and leave the VM on the laptop

• Type 1 vs Type 2 – a religious debate! Table on next slide:

Security

Type 1 vs Type 2 Client Hypervisors

• For hosted virtualization types, the user experience is determined by the display protocol

• 1) Intelligent client protocols– Microsoft RDP, Quest EOP (for RDP), Citrix ICA/HDX– Uses client resources to draw graphics and play multimedia– Better server scalability– Works on WAN/VPN/Internet– Multimedia apps need to be supported individually

• 2) Bitmap remoting– Teradici PCoIP, Microsoft RemoteFX, Red Hat SPICE?, HP

RGS?– Bitmap remoting allows for simpler, cheaper clients but

requires more server resources and network bandwidth– Automatically supports all apps

Display Protocols

• Possibilities:– Full-screen Flash with EOP Multimedia Acceleration over

WAN if connectivity allows– Effect of EOP GA on animation– Effect of EOP Xtream on latent connections

Short Demo

• 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...

• 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

• 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

• Let’s look at some case studies

So What Do I Do?
