User Data

In most environments, the components are linked together in ways that are difficult to support and maintain.

Could a Virtual Desktop be the answer?

Desktop OS Virtualization breaks the link

Create conflict free applications
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


How thinapp works
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
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
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

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
