  • 22. History in short • Citrix turned Windows in to a multi-user operating system and became a leader in Server Based Computing in Windows world • VMware became a leader in server virtualization • In 2005-2006 term VDI was introduced, which may be considered as a hybrid of SBC and server virtualization • Both Citrix and VMWare was playing like kids in 1st grade, but became older • Microsoft is slow in adopting new ideas, in fact there is no releases between operating system releases
  • 23. Trends • • • • • • Migrating old workstations to the datacenter Using blade PCs Moving to cheaper thin clients VDI started as an alternative to terminal services Users became mobile Lack of technical benefits of VDI was compensated by a ―lower TCO‖ speech • VDI supposed to make OS migration easier
  • 24. VDI Expectations Source: Gartner’s Chris Wolf (
  • 25. VDI Adoption Source: Gartner’s Chris Wolf (
  • 26. VDI Adoption Source : Forrester (
  • 27. VDI Adoption • According to Simon Bramfitt from Entelechy Associates, 55% of the companies have VDI in test environments ( • In report prepared by Jeroen van de Kamp and Ruben Spruijt from Project Virtual Reality Check, The majority of people (31,91%) is using VDI in pre-production, or early production (34,92%). ( • By 2016 30% of large organizations will have deployed HVDs to 20% of their users (Gartner ) • Many customers don’t realize that they actually use desktop virtualization for years.
  • 28. How Market Keep Desktop Virtualization On the Top Of the Hype? • Desktop-as-a-Service is here to help • • Hundreds of cloud service providers Special licensing from vendors • VDI vendors turn to virtual desktops • • • • Wanova Virtual Computer RTO Software Application virtualization vendors
  • 29. Competition “ VDI vendors are not competing against each other. They’re competing against the status quo. They’re competing against those pallets full of Dells that you’ve been buying for the past twenty years Brian Madden, ―The VDI Delusion‖ ”
  • 30. Summary • VDI is not new • VDI started as an initiative of converting physical desktops into a VM • In the beginning of 2009, Gartner said that Hosted Virtual Desktop market will surpass $65 Billion in 2013 and have 49 million users ( • All vendors made a lot of acquisitions to make their products look more competitive

  • 75. What Is Layering? • Way to define a container that contains relevant registry keys and files • Not possible on a block level • Application deployment ≠ application layering • OS deployment ≠ OS layering
  • 76. Why Layering Is Good? • Manage each layer separately • User data stored separately, making backup easy • OS and App layers can be generalized and shared between instances • Rollback each layer independently • Great for non-persistent deployments
  • 77. Layers In A Real Life • • • • • • Difficult to separate User Data from User Settings Per-app user settings are merged in a user profile Layering adding a performance overhead Number of golden images grow Complexity Say good bye to your desktop management experience
  • 78. Pros of persistent desktops One-to-one Your helpdesk know what to do Performance Familiar management tools Users get what they expect SCCM, Altiri s, Ghost, La nDesk Users store their files in weird locations
  • 79. Cons of persistent desktops One-to-one Familiar management tools Users get what they expect Best way to make your storage vendor happy Each instance managed individually Users can ruin your environment
  • 80. Pros of non-persistent desktops Less storage New ways to manage your images Locked-down desktops Share your golden image Ideally one golden image Just reboot for refresh
  • 81. Cons of non-persistent desktops Less storage New ways to manage your images Locked-down desktops Harder to manage IOPS Old management tools doesn’t work App virtualization is required No personalization

  • 90. How To Fail Or Succeed With Desktop Virtualization & Workplace Mobility Application Virtualization and User Profiles, How Does it Work? Denis Gundarev @fdwl, Entisys Solutions
  • 91. What is Application Virtualization? • Application is executed inside the sandbox isolated from operating system • Improves security (isolates insecurity) • Eliminate application conflicts Package Deliver Execute
  • 92. Every time you disable UAC… Steve Ballmer kills a kitten Please, think of the kittens
  • 93. Every time you: • Modifying ACLs on Program Files or HKLM • Making user a local admin • Just give users SeBackup, SeRestore, SeCreateGlobal and SeLoadDriver privileges, but keep them as standard users
  • 94. Application Virtualization Example
  • 95. Application Isolation Environments Was introduced in MetaFrame Presentation Server 4.0 (2005) Virtualization layer that redirects system resources Virtualizes: – File system – Registry – Named objects (events, semaphores, etc) Transparent to the application Was a great compatibility aid for: – Applications which are not multi user friendly – Applications which have problems coexisting on the same server – Applications that cannot have multiple instances running simultaneously
  • 96. Isolation Environment Roots Specifies directories and registry locations User Profile Root – Changes made by the user reside here – Suitable for Multi-user incompatible applications Installation Root – Per Isolation environment location – Enables conflicting applications to coexist
  • 97. Isolation Environment Rules • Three types of Rules: • Ignore • Redirect • Isolate
  • 98. Isolation Environment: IGNORE Rule Used to create ―holes‖ in an isolation environment Virtual address is not modified by the virtualization system Used to allow access outside of the isolation environment
  • 99. Isolation Environment: REDIRECT Rule Redirects an application request for a file or registry key to a specified location – If an application creates the file, c:tempdata.txt, regardless of the user, then it might be sensible to redirect those files to c:aietemp%USERNAME% – This means, if UserA ran the application isolated, then c:tempdata.txt is created in c:aietempUserAdata.txt
  • 100. Isolation Environment: ISOLATE Rule Per User: – Ensure that each user gets his own copy of the requested resource Per Isolation Environment: – A single copy of the required system resource is created in the installation root location and shared by all users
  • 101. Application Streaming Introduced in Citrix Presentation Server 4.5 (2007) Added delivery mechanism to AIE Had 6 major releases before being deprecated in 2013 Still available with XenApp 6.5 and XenDesktop 5.6 Completely removed in XenDesktop 7
  • 102. Application Virtualization Internals
  • 103. How it works Two main components of Application Virtualization: – Isolation/Redirection – Delivery mechanism Optional features: – – – – File type associations and OS integration Rights Management and usage tracking Packaging Shareable sandboxes
  • 104. File I/O Redirection options API Hooking – at USER or Kernel Level • Hooking CreateFile, OpenFile, DeleteFile, NtCreateFile, NtOpenFile, NtDeleteFile etc • Hooking into System Service Descriptor Table (SSDT) File System Filter Driver or Mini-Filter – Write file system driver to redirect virtualized file requests.
  • 105. Registry Redirection Options API Hooking at USER Level – Hooking advapi32.dll - RegCreateKeyEx, RegDeleteKeyEx etc – Hooking Ntdll.dll – NtCreateKey, NtDeleteKey etc API Hooking at Kernel Level – Hooking SSDT – NtCreateKey, NtDeleteKey etc
  • 106. Application Virtualization Vendors
  • 107. Application Virtualization Products Microsoft App-V VMware ThinApp CloudVolumes Symantec/Altiris SVS Spoon (Novell ZENworks) Numecent Jukebox FSLogix Sandboxie Microsoft Windows
  • 108. Microsoft App-V Version 2.0 was released in 2002 by Softricity ~8 major and ~50 minor releases before App-V 5.0 App-V 5.0 is completely rewritten and released in 2012 Available as a part of MDOP under SA
  • 109. App-V 5.0 Cons Requires SA User-level apps only Cannot virtualize drivers Cannot isolate applications that are a part of the OS
  • 110. App-V Pros Tons of information on Internet Huge user community Integration with System Center Integration with XenDesktop Managed by PowerShell
  • 111. VMware ThinApp Uses user-mode hooks Application packaging solution, just like Emulates Windows COM and DCOM Supports Streaming Execution (SMB/CIFS) and Deployed Execution (i.e. USB) Does not support installed Apps No centralized management (for standalone product) End of availability (―EOA‖) of VMware ThinApp, effective on December 15, 2013. After that will be available only as a part of View or Horizon
  • 112. CloudVolumes AppStack – basically a VHD or VMDK attached to a VM Web-based management console that communicates with hypervisor Full support for server software Available Now: VMware ESX 5.0, 5.1, Coming soon… HyperV, Azure, Amazon EC2

  • 125. Sandboxie • Isolated sandboxes for applications • Virtualizes Files, Disk Devices, Registry Keys, Process and Thread objects, Driver objects, and objects used for Inter-process communication: Named Pipes and Mailbox Objects, Events, Mutexs (Mutants in NT speak), Semaphores, Sections and LPC Ports • Not designed for VDI • Not designed for Enterprise • Developed by one person
  • 126. Microsoft Windows • UAC Virtualization is available out of the box • Application compatibility toolkit can be used to manage folder and registry redirection • No additional software needed
  • 127. What Are Shims? Applied to specific apps – Configured with Compatibility Administrator in the App Compat Toolkit – Deployable to enterprise Changes what the app thinks it sees Does not change what app is allowed to do
  • 128. What Are Shims Good For? Great for many kinds of bugs: – – – – – – Bad Windows version checks Writing to HKCR at runtime Unnecessary checks for ―am I admin?‖ Writing to WRP-protected keys and files Windows thinks your app is an installer File/Registry redirections

  • 132. Conclusion
  • 133. How To Fail Or Succeed With Desktop Virtualization & Workplace Mobility What Happens When Technology Meets Marketing? Denis Gundarev @fdwl, Entisys Solutions
  • 134. Security • • • • • Desktop Virtualization ≠ secure environment Non-persistent VM = disposable gloves for hacker Non-persistent VM ≠ Virus Protection SSL ≠ Secure connection Disabled clipboard+disabled drive mapping ≠ DLP
  • 135. ― Horizon View offers ease of management along with a secure, robust architecture, and the ability to offer end users the freedom and choice they need to be productive. In comparing VDI and sessions, VDI offers the following advantages over sessions: • Eliminates application-compatibility issues • User or OS resets do not impact other users (sessions require resetting entire server) • Provides better native-application compatibility • Eliminates application-to-application conflicts in a multi-session Environment • Applications do not have to be written with TS or RDSH in mind (i.e., desktop applications are supported) ‖ Source: VMware (
  • 136. Application compatibility • Most of the appcompat issues caused by migration to the new OS generation • Windows OS is stable • Windows Client is not much more stable than Windows Server • Applications that work on Windows 7 in 99% of cases will normally work on Windows Server • Virtualization is not a solution, it’s workaround
