  1. Tim Mangan TMurgent Technologies Microsoft MVP for Application Virtualization Application VirtualizationConcepts and Platforms

  2. Virtualization Encapsulation Use as ifin original environment Isolation

  3. Application Virtualization? Server Virtualization • Server Consolidation • Share hardware resources Application Virtualization • App Compatibility • Central App Management Primary Partition Virtual Machine A Virtual Machine B Virtual Machine C Guest OS Services and Applications Guest OS Services and Applications Guest OS Services and Applications Guest OS Guest OS Guest OS Hypervisor Host Hardware

  4. Application Virtualization! • Eliminate conflict between applications • DLL Hell • Need different versions of required component (e.g.: Java) • Different versions of same application • Customize app to the task • Centralized Management • Install and configure once (offline) • Monitor application usage • Enforce vendor license agreements • Portability / Flexibility • Dynamic IT!

  5. Components of AppVirt • Encapsulation • Execution • Encapsulation • Publication • Delivery • Execution All Vendors

  6. Encapsulation • Offline process • Sequencing, Profiling, etc… • “Clean PC” (Virtual PCs!) • Install and configure application • Create a portable package • May/may not include virtualization client • Test

  7. What Is An Application? • Files • Executable Components • Configuration • Data • Registry • Machine/OS Related • App Related • User Related • Integrations • With OS/Machine • With Other Applications

  8. Encapsulation • Packaging Effort • Process • Take “clean” PC • Minimum common image • Install App • Run App (license etc…) • Customize App • Documentation • Have “App Expert” verify

  9. Delivery • File Transfer • Network share • Thumb drive / CD • MSIs • Streaming • On demand delivery • Three levels: • Package: All bits must arrive before execution • File: Entire file must arrive before use • Block: Parts of file needed before use

  10. Block Level Streaming • Average 10 – 30% needed to start • Less than 50% ever used

  11. Publishing • Access and authorization • Shortcuts • Start Menu “All Programs” • Desktop • Quick Launch Bar • Shell Integrations • File Type Associations • .DOC  msword.exe • Icon Representations • “Send To” • “New File”

  12. Publishing (continued) • Per machine or per user? • Consider Terminal Server use • Non-company owned equipment

  13. Execution • Redirection Style Isolation • Only virtual app can “see” files/registry • Virtualization • More complete isolation • Protection of App/OS components • Layered integration

  14. Ultimate Goal • State Separation Presentation

  15. App Virtualizaiton Example Windows Registry Non virtualized Applications, Services, dlls, and COM components Virtual Application X Files (Data) User Profile Virtualization Settings Package Virtualization Settings

  16. Virtual App Execution

  17. Vendors • Microsoft App-V (formerly SoftGrid) • Citrix XenApp App Streaming (formerly AIE) • VMware ThinApp (formerly Thinstall) • Symantec (Altiris SVS/AppStream) • InstallFree • Xenocode • EndeavorsTechnology

  18. Vendor: Microsoft • Microsoft App-V • Purchased Softricity SoftGrid 2006 • Version 4.5 – release Sept 8 2008 • Oldest, most feature complete • Client based – full virtualization • Publishing per user or per device • Streaming, Pseudo-Streaming, or MSI • Reporting and License Compliance

  19. Vendor: Citrix • Citrix XenApp App Streaming (formerly AIE) • Developed in-house • First Release ~2005 • Client based nearly full virtualization • Publish per-user (same as non-virtual) • Desktop or TS scripted choice • Pseudo Streaming • Integrated reporting if TS

  20. Vendor: VMware • VMware ThinApp (formerly Thinstall) • Purchased Thinstall 2008 • First Release? • Clientless • No publishing today • File copy delivery

  21. Vendor: Symantec • Symantec Workspace Virtualization (AltirisSVS/AppStream) • Purchased multiple companies • AppStream: • Client Based • Isolation • Streaming • SVS • Publishing • Reporting • Best Potential to compete, but slow in integrating components… • See http://eval.symantec.com/mktginfo/enterprise/fact_sheets/b-datasheet_endpoint_virtualization_suite_02-2009.en-us.pdf

  22. Vendor: InstallFree • Formed 2006 – First product April 2008 • Thinstallclone called “Bridge” • Some Central Publishing • Block level streaming – but user mode

  23. Vendor: Xenocode(Code Systems) • Founded 2002 – but focused elsewhere • Announced switch to App Virt in June 2008 • OEM deal with Novell • Virtual Application Studio – in Beta

  24. Vendor: Others • StreamTheory/Tadpole/Endeavors/Arcsael • “Ceedo Enterprise” (www.ceedo.com) • FastScale Composer (www.fastscale.com) • Greenborder • RingCubeMojoPac (www.ringcube.com) • Trigence AE (www.trigence.com) • Trustware (www.trustware.com)

  25. Factors to consider Client or Clientless Centralized Delivery and Management Copy or Streaming Delivery Desktop / Terminal Server OS support 32 bit / 64 bit support VirtApp Isolation (avoid conflicts) VirtApp Cooperation (avoid over isolation) What can’t be virtualized?
