2. Desktop Infrastructure Challenges • Distributed workforce • Mobile & remote workers • Outsourcing & off-shoring • Contract Workers • Limited control of PCs • Patch compliance • Security • Regulatory compliance • Management complexity • Deployment • Support • Security • Focus on PC hardware • Many makes & models • Refresh cycles • Reducing Cost • CAPX/OPX

3. Typical Corporate Desktops The corporate desktop PC model has changed little in nearly 2 decades. User Data Applications Operating System Hardware

4. Typical Corporate Desktops User Data In most environments, the components are linked together in ways that are difficult to support and maintain. Applications Operating System Hardware

5. Problems Can Start At Any Layer ? User Data A problem at one layer often causes a chain reaction that can destroy the whole stack. Applications Operating System Hardware

6. Local Failures Can Mean Data Loss @%#! This makes recovery difficult and threatens any locally stored user data and settings. Most organizations just replace or re-image the whole PC. User Data Applications Operating System Hardware

7. There has to be a better way… Could a Virtual Desktop be the answer?

8. VDI Enables Hardware Independence User Data Desktop OS Virtualization breaks the link between the Operating System and any specific hardware. Applications Operating System Hardware

9. Virtual Desktops Leverage File Servers Effectively VDI proximity to the data center also enables data isolation through file shares and profile management. User Data Applications Operating System Hardware

10. File Shares and User Profiles Data This allows users to access any VM and always get their data and their profile. Apps Apps Apps OS OS OS Virtualized Hardware

11. Virtual Machines with Everything Data We could install all of the applications that everyone needs in all of the machines. OS OS Virtualized Hardware

12. Overall System Instability Data And the more applications you install, the less stable things tend to get. OS OS Virtualized Hardware

13. What’s new with VMware View 3 VMware View 3 Unified Access ThinApp View Composer Offline Desktop (experimental) Virtual Printing Reduce app conflicts Increase density Reduce support costs Increase laptop security and recovery Reduce storage costs

14. vClone Direct Storage Cost Savings Dramatically (90%+) reduce the amount of storage consumed Increase overall performance due to better storage controller / cache utilization. 25 MB Clone Ratio % Savings 25 MB Clone 1:50 85%+ 1:100 90%+ 25 MB Clone 1:1000 95%+ 10 GB OS

15. Create Conflict Free Applications Problem: Tightly coupled relationships between OS, Applications and Data • Symptoms: • Application Conflicts • Complex Compatibility Test Matrices • Diminished Time to Deployment • Loss of User Productivity Solution: VMware ThinApp Agentless application virtualization decouples applications and data from the OS

16. How ThinApp Works: VMware ThinApp links the application, Virtual Operating System (VOS), file system and registry into a single EXE/MSI file • Application Encapsulation & Isolation • Intercepts file and system calls • Process Loading- start exe from VOS, Launch from host OS (Virtual/Physical).   • DLL Loading. loads DLL dependencies the EXE/DLL/OCX files from archive • Thread & Process Management. VOS tracks all processes and threads inside virtual registry (COM & Utility)

17. Simplify Desktop Delivery & Costs with VDI & ThinApp • Reduce Storage • Reuse templates • Install VM without apps • Simplify Software Delivery (no agents/infrastructure) • Multiple versions of same app installed on VDI image • Many ways to deliver shortcut • Plugs into existing App Mgmt tools w/o infrastructure • Streamline Patch Updates • Modify 1 app for whole environment • In place upgrades

18. Unified Access • Support other platforms accessible by RDP • Terminal Server • Blade PCs • Physical PCs • Increase in device support • Broader USB • Smart Card and CAC • Universal Printer Blade PCs Physical PCs Terminal Servers

19. Virtual Printing Driver Free Printing: No Installation and Maintenance of printer drivers on Virtual Desktops All necessary printers automatically available Minimize network utilization up to 98% with advanced print stream compression High quality printing even over WAN connections Use of client printer driver rather than complicated server installations RDP RDP View Client View Client

20. Offline Desktop Offline VDI • End-users can check-in and check-out their virtual desktops • Administrators can extend security policies to the local computer • Near approximate of the full local experience Offline VDI

21. Let’s bring it all together… Unified Access SVI VDM VC Offline AD Clients Linux / Partner Clients

22. Don’t Make Big Virtual Machines Data So instead of installing everything into huge cumbersome VM’s. OS OS Virtualized Hardware

23. Create the Smallest VM Possible Data We install nothing but the OS from a single template. OS OS OS Virtualized Hardware

24. Deliver Apps and Data on Demand Data And deliver applications on demand from a file server. OS OS OS Virtualized Hardware

25. Deliver Apps and Data on Demand Data Data Based on what the user actually needs or has permission to use. OS OS OS Virtualized Hardware

26. A Single Location for Applications Creating a software repository. Data Data V1 OS OS OS Virtualized Hardware

27. No Distribution Needed Eliminating the need for software distribution. Data Data V2 OS OS OS Virtualized Hardware

28. Thinapp Blocks System Changes And we store the sandbox in the profile where it can follow the user. Thinapp System Content Sandbox User Space System Files Registry Files Registry

29. Deploying Updates… User data disks are “connected” to the new master at next login or user prompt. IE7 IE6

30. Creating vClones Create a baseline Windows virtual machine on your Virtual Infrastructure. V1 OS

31. Building Desktops with vClones This replica will then create a set of small linked clones and join them to the domain. V1 V1 OS OS

32. Building Desktops with vClones Profiles are stored as user personality disks, created on first logon if necessary. VM V1 V1 OS OS OS

33. Building Desktops with vClones User data is stored on virtualized file servers. V1 V1 OS OS

34. Building Desktops with vClones Thinapps are launched from network shares V1 V1 OS OS

35. Building Desktops with vClones The user’s PC is the resulting combination. V1 V1 OS OS

36. Building Desktops with vClones Update the baseline Windows VM with a patch. V2 V1 OS OS

37. Building Desktops with vClones Publish the new SVI source VM. V2 V1 V2 OS OS OS

38. X Building Desktops with vClones X X X X X As users log out, the clones are deleted… V2 V2 OS OS

39. Building Desktops with vClones …and attached to the new master replica. V2 V2 OS OS
