Agenda
• Overview of VDI• Benefits of Hosted Desktops• VDI Drawbacks• Key Players• Microsoft• Citrix• VMware• Feature Comparison• Licensing Comparison• What is Right for You?
Overview
• SBC - Server Based Computing– What’s old is new again!– Thin Client Computing
• Virtualization– Decoupling OS from hardware– Sharing hardware resources
• VDI - Virtual Desktop Infrastructure– Hosted virtual desktops– Hybrid of SBC and virtualization
Expectations
2008 IDC Report
Desktop Management
• TCO for the traditional corporate desktop– $3500 and $5000 per user, per year– End user operational costs nearly 45%
• Hosted virtual desktops 2% to 12% more cost effective than traditional PCs

*Gartner TCO Comparison of PCs with Server-Based Computing
Components
• Virtualization platform– Highly available, resource load balancing
• Connection Broker• Endpoint
– Desktop, laptop, thin client
• Hosted desktop• Application
deploymentprocess/solution
Benefits
• Longer life of endpoint devices*• True user mobility• Centralized administration• Improved security
– All data stored in datacenter *• Speed of deployment
– New user– New operating system– Updates / patches
• Single image – hardware independence– No longer need multiple images
• Better hardware utilization• Higher availability
Drawbacks
• Large initial investment– Servers for virtualization infrastructure– FC or iSCSI SAN for shared storage– Network infrastructure
• More expensive than other SBC solutions– Cost benefit analysis
• IT training– Steep learning curve: virtualization, application
management, user state• Reliance on network connectivity*• End-user experience
Key Players
• VMware – View– Virtual Infrastructure / vSphere
• Citrix Systems – XenDesktop– XenApp (Presentation Server)– XenServer
• Microsoft – Remote Desktop Services (Terminal Services)– Hyper-V– Windows Server and workstation operating
systems
Microsoft
• Remote Desktop Services– Remote Desktop Connection Broker– Web Access and RemoteApp– Remote Desktop Virtualization Host– Remote Desktop Gateway
• Windows Server 2008 R2• Microsoft Hyper-V• System Center Virtual Machine Manager
Virtualization
• Microsoft Hyper-V R2– Live Migration (Failover Cluster Role)– Shared Cluster Volumes– Integration with System Center Operations
Manager 2007• Virtual Machine Manager
– Management of Microsoft virtualization– Single Administrative view– Templates, cloning, library, PRO Tips
Remote Desktop Services
• Connection Broker– Desktop pools
• Secure remote access– Remote Desktop Gateway
• Web Access• RemoteApp

Virtualization
• XenServer– Live migration with XenMotion– XenCenter for management– High availability with resource pools
• Platform support– Open architecture– Any endpoint device– Any virtualization platform
XenDesktop
• Desktop delivery controller• Citrix receiver, agent, web console• Desktop pools
– Pool– Assigned
• Persistent• Non-persistent
• Desktop availability– Work hours
Provisioning Server
• One to many– Streaming OS to endpoints– vDisk image
• Private to one desktop• Shared with many desktops
– WriteCache• Local, server, RAM
– Not restricted to only virtual machines
XenApp
• Citrix Presentation Server• Virtualized application delivery
– Use XenApp server for processing• Streaming application delivery
– Use virtual desktop for processing
– Sandbox– Pre-caching
Profile Manager
• Windows service that monitors logon and logoff
• Maintain settings across devices• Granular control of profile
– Reduce profile bloat• Settings deployed via GPO• Logoff
– Only changes synchronized• Logon
– Local profile synchronized
VMware
• View• vSphere - ESX/ESXi
– High Availability– Distributed Resource Scheduler– vMotion
• ThinApp– Application virtualization
vSphere

Conclusion – Which is Right for Me?
• A Few Questions to Ask Yourself:– Do virtual desktops still make sense for you?– Do you already have one of these vendors in
your environment and have experience with it?– Is there a particular feature that is very
important to you available in only one of the vendor’s solutions?
– Are you already partially or fully licensed for one of these solutions?
– Do you have in-house expertise or a qualified partner to help you with the solution?
