9. Virtual Desktop Infrastructure (or VDI) is an architectural model where a client OS
runs in a server-based virtual machine environment and interacts with the user via a
network connection.

with sophisticated IT
in highly regulated industries
Flexibility of access Business Continuity
Personalized desktops at shared Quicker recovery from device
terminals malfunctions
Work from home and approved Centralized data storage and backup
offsite locations without the reduces losses from stolen devices

Reduced IT travel to user workstations for support
Improved desktop lifecycle management through
quick access to centralized desktops.

Large Scale Deployment: Microsoft+Partner
Technology
Citrix XenDesktop or Quest vWorkspace

12. Virtual Desktop Access (VDA) -> License to access Windows OS
Hyper-V 2008 R2 -> Server Virtualization to host the VM’s
SCVMM 2008 R2 -> VM Provisioning
Windows 2008 R2 RDS -> Connection Broker
MS Application Virtualization -> Application Provisioning

14. Scalability: When do I use partner solutions?
Microsoft Inbox: Low complexity environment
Microsoft+Partner: Enterprise-ready
SCALE
100’s # of users 1,000’s
< 10 # of 100’s
few # of images many
MANAGEMENT
single # of sites multiple
static image placement dynamic
OS-level user profile advanced
CLIENT EXPERIENCE
LAN only connectivity LAN / WAN
Windows only client platform Windows / non-Windows
limited local peripheral support comprehensive

15. Partner Connection Broker Checklist
Low-Complexity Environment Enterprise-ready Environment
Microsoft VDI with
Microsoft VDI only
3rd Party Connection
Connection Broker
Broker
 Single site/location  Multiple sites/locations
 Static image placement  Dynamic image placement
 Single virtual desktop pool  Multiple virtual desktop pools
 Single, non-clustered broker  Multiple brokers in failover
configuration
 LAN-only connectivity
 LAN & WAN connectivity
 USB support limited to PnP
devices  Generic USB support

16. *If you already have Windows SA on your devices, then you don’t have to pay for the VDA license.
Note: Non-windows devices are not covered by Windows SA such as iPAD and Android devices.
VDI Platform:
Server and
Management
MDOP, SCCM CML and RDS CAL*
Technology
*RDS CAL is only required if you will also be using XenApp component of XenDesktop
Enterprise Value
AccessPartner
Add: Points Partners add value to the Microsoft VDI Solution
(PC, Thin clients)
Technology
Microsoft recommends that you consider partner solutions when you have enhanced needs of scale,
(such as multiple site requirements), manageability (which could support advanced provisioning
scenarios) or user experience enhancement such USB and Flash remoting.

17. Desktop Virtualization = VDI
VDI will save money immediately
All users will benefit from VDI
VDI is the future of the desktop
VDI is just one of many tools to virtualize your desktop

18. Hardware Costs
Storage
Redundant Links
Software costs is only about 1/3 of the total cost.
Consider other solutions for centralized
management. Remember VDI is just one of the
many solutions to achieve this.

19. Windows Remote Desktop Services (formerly
Terminal Services)
App-V+SCCM. Both works on physical and
virtual desktops

20. VDI is expensive and it will not reduce TCO.
Consider using Remote App:
Server Role in Windows 2008 and Windows 2008 R2
Also provides Seamless User Experience
Compared to VDI, the hardware requirements
are not as high.
It is basically the same Terminal Services
technology (RDP)
Partner Solution: consider XenApp.

24. Common requirement for VDI = Centralized
Management
There are existing technologies already that are
much cheaper than VDI
Combine System Center, App-V and Folder
Redirection…and of course a good standard
desktop policy.

26. Use MED-V for App-to-OS compat issues. MED-V is part
of MDOP.
Upsides for VDI:
VDI offers better user operating system isolation
VDI has better native application compatibility
VDI allows users to be admins of their own images
App-V complements VDI
Upsides for Session Virtualization:
Session Virtualization requires less hardware than VDI
Sessions are cheaper than VDI desktops
Server management is less than VDI
Can also use App-V
Remote Desktop Services enables both session virtualization
and VDI!

27. Improves Application Compatibility
• prevents one app conflicting with another
• Prevents one app conflicting with other instances of itself
• Fixes many issues where app wouldn’t run as standard user
Enables Consolidation of Session Hosts
• No longer any need for silos of session hosts
• Allows session hosts to be homogenous
Improves user profiles
• Application settings can be stored to network location / roamed
independently
• Increases usefulness of mandatory profiles
