  6. 6. Agenda• Overview of VDI• Benefits of Hosted Desktops• VDI Drawbacks• Key Players• Microsoft• Citrix• VMware• Feature Comparison• Licensing Comparison• What is Right for You?
  7. 7. 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
  8. 8. Expectations 2008 IDC Report
  9. 9. 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
  10. 10. Physical vs. VirtualCost Physical Virtual Desktop DesktopClient hardware $900 $450Server hardware - $250Virtual desktop solution - $120PC deployment costs $185 $25Operations: Support, software $600 $392deployment, backup, security, virusprotectionEnd-user operations: Training, self- $2215 $1854supportAnnual downtime cost $90 $30TOTAL $3990 $2821 *Gartner TCO Comparison of PCs with Server-Based Computing
  11. 11. Components• Virtualization platform – Highly available, resource load balancing• Connection Broker• Endpoint – Desktop, laptop, thin client• Hosted desktop• Application deployment process/solution
  12. 12. 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
  13. 13. 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
  14. 14. 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
  15. 15. 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
  16. 16. 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
  17. 17. Remote Desktop Services• Connection Broker – Desktop pools• Secure remote access – Remote Desktop Gateway• Web Access• RemoteApp
  18. 18. Connection Manager• Remote Desktop Connection Manager – Load balancing of connections – Hosted Desktop • Assigned – User assigned to dedicated desktop • Pool – User connects to any available desktop• Remote Desktop Gateway – Secure remote access to desktops
  19. 19. Application Deployment• System Center Configuration Manager – Lite or Zero touch OS deployment – Application deployment• Remote Desktop Services – RemoteApp• App-V – Application virtualization
  20. 20. App-V• Acquisition of Softricity – Originally renamed SoftGrid• Application virtualization – Application sandbox – Streaming – Deployment – Dynamic Suite Composition
  21. 21. Profile Management• Profile Management – Microsoft roaming profiles – Maintain settings across devices• Folder redirection – User files stored on server – Flexibility in hosted desktop

  24. 24. XenDesktop• Desktop delivery controller• Citrix receiver, agent, web console• Desktop pools – Pool – Assigned • Persistent • Non-persistent• Desktop availability – Work hours
  25. 25. 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
  26. 26. XenApp• Citrix Presentation Server• Virtualized application delivery – Use XenApp server for processing• Streaming application delivery – Use virtual desktop for processing – Sandbox – Pre-caching
  27. 27. 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

  38. 38. 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?
