Typical Corporate Desktops
The corporate desktop PC model has changed little in nearly 2 decades.
Typical Corporate Desktops
In most environments, the components are linked together in ways that are difficult to support and maintain.
Problems Can Start At Any Layer
A problem at one layer often causes a chain reaction that can destroy the whole stack.
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.
There has to be a better way…
Could a Virtual Desktop be the answer?
VDI Enables Hardware Independence
Desktop OS Virtualization breaks the linkbetween the Operating System and any specifichardware.
Virtual Desktops Leverage File Servers Effectively
VDI proximity to the data center also enables data isolation through file shares and profile management.
File Shares and User Profiles
This allows users to access any VM and always get their data and their profile.
Virtual Machines with Everything
We could install all of the applications that everyone needs in all of the machines.
And the more applications you install, the less stable things tend to get.

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

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 View Client

Let’s bring it all together…
Don’t Make Big Virtual Machines
So instead of installing everything into huge cumbersome VM’s.
Create the Smallest VM Possible
We install nothing but the OS from a single template.
Deliver Apps and Data on Demand
And deliver applications on demand from a file server.
Deliver Apps and Data on Demand
Based on what the user actually needs or has permission to use.
A Single Location for Applications
Creating a software repository.
No Distribution Needed
Eliminating the need for software distribution.
User SpaceSystem
And we store the sandbox in the profile where it can follow the user.
Thinapp Blocks System Changes
Deploying Updates…
User data disks are “connected” to the new master at next login or user prompt.

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

This replica will then create a set of small linked clones and join them to the domain.
