7. Virtual Desktop Infrastructure - Web Application Acceleration WEB APPLICATION ACCELERATION Web Application Acceleration Providers Citrix Netscaler Hardware Appliance Cisco Unified Computer Services (UCS) F5 BigIP 2

8. Virtual Desktop Infrastructure - Connection Broker CONNECTION BROKER Dedicated Desktop Pooled Desktop Connection Broker Providers Citrix with XenDesktop 5 Microsoft with Remote Desktop Services (RDS) VMware with View 4.5 3

9. Virtual Desktop Infrastructure - Application Streaming & Virtualization APPLICATION STREAMING & VIRTUALIZATION Install application on server; execute on local machine. Advantages: installation, upgrade, roll-back, delivery speed, ease of application support (management). Application Virtualization Providers: Altiris/Symantec Workspace Virtualization Citrix Application Streaming Microsoft App-V VMware ThinApp 4

10. Virtual Desktop Infrastructure -OS Provisioning OS PROVISIONING Single image on multiple workstations Advantages: upgrade or roll-back an OS quickly. When virtual desktops use OS provisioning, (valuable) storage is saved OS Provisioning Providers: Citrix Provisioning Server, part of the XenDesktop and XenApp family, DoubleTake Flex, Wanova Mirage and the VMware View Composer 5

11. Virtual Desktop Infrastructure - Server-Hosted Virtual Desktop (VDI) SERVER-HOSTED VIRTUAL DESKTOP (VDI) Two kinds of VDI: server-hosted desktop With server-hosted, desktops no longer bound to a location. Client display is delivered via Microsoft RDP, Citrix ICA/HDX, Teradici/VMware ―PC-over-IP client-hosted desktop Server-Hosted VDI Providers: Microsoft, Citrix, Kaviza, Quest, Oracle/SUN and VMware 6

12. Virtual Desktop Infrastructure –Server-Hosted VDI GPU Acceleration SERVER-HOSTED VIRTUAL DESKTOP WITH GPU ACCELERATION Rich Media Experience VDI with GPU Acceleration Providers: Citrix HDX 3DPro Microsoft RemoteFX Teradici HP RGS 7

13. REMOTE DESKTOP SERVICES (RDS) (Also known as Shared Remote Desktop) Every user has unique terminal server session that runs in the data center Programs execute centrally on terminal server versus locally on desktop desktop or application is location independent Low TCO Remote Desktop Services (RDP) Providers: Microsoft Citrix Quest Virtual Desktop Infrastructure – RDS (Terminal Server) 8

14. CLIENT-SIDE DESKTOP VIRTUALIZATION (VDI). (Also known as Client Hosted Virtual Desktop) virtual machines run locally on the client device Advantages: hypervisor ensures that each virtual machine is hardware-independent simultaneously use a number of virtual machines at the same workstation Two types of hypervisors: bare-metal client - Citrix XenClient bare-metal hypervisor client-hosted hypervisor - Microsoft Virtual PC and MED-V, VMware ACE and Fusion, VMware View Client with Local Mode and Sun VirtualBox Virtual Desktop Infrastructure – Client-Side Desktop Virtualization (VDI) 9

15. Client Management Services Features: OS deployment Patch management Application and client deployment Asset management Service desk integration Remote control Client Management Providers: Altiris Deployment Solution, HP Configuration Manager, IBM/BigFix, Intel LANdesk Client Management, and Microsoft System Center Configuration Manager (SCCM) Virtual Desktop Infrastructure – Client Management Services 10

16. Virtual Desktop Infrastructure – Web Application Acceleration Web Application Acceleration Web Application Acceleration appliances accelerate and secure web-architected applications Web Application Accelerator Providers: Citrix Netscaler F5 BigIP Microsoft Desktop Optimized Pack (MDOP) 11

17. Benefits of Application Virtualization – Citrix XenApp* Eliminate application conflicts and OS instability resulting from desktop application installation Reduce the costs associated with regression testing, deployment, maintenance, updates, and de-provisioning for applications running locally on users‘ machines Offer applications as an on-demand service Lower support costs by automatically updating and repairing applications every time they are used Speed regulatory compliance by eliminating the need for extensive testing to certify applications Enhance security by giving IT administrators complete control over applications delivered to desktops, even those of unmanaged partners and users * Citrix XenApp is included in Citrix XenDesktop Platinum

18. Benefits of Application Virtualization: Microsoft App-V Transforms apps into centrally-managed virtual services that are never conflict with other apps. Streams applications on-demand to any device. All applications are instantly available on any licensed device depending on user rights Standalone mode provides app caching on the local client for offline usage App usage & license metering are managed centrally Patch or upgrade once to the server Fully integrates with SCCM
