2. Client Computing Versus Server Based Computing
`
Client based computing
`
1. Need to manage each client
* e.g. Install / Upgrade / Trouble-shooting
(may need to visit on-site which takes time)
2. Need to control policy
* e.g. Unnecessary appl. Install / Data Backup / Data leak
Server based computing
1. Only need to manage server
* Provide latest apps to users
Less trouble / Remote support (image rollback)
2. Centralized control policy
* Systematically apply standard policy to clients
`
`

3. Benefits of Server Based Computing
• Highly Agile Desktop/Application Delivery
• Highly Available Desktops
• Much Better Hardware Utilization
• User Endpoint Independent Computing
• Better Automation of Desktops
• Quick Resolution to Support Issues
• Lower Support Issues
• Migration to new OS is simple and very cost effective

5. Use Cases: SHD vs DVD
Key Points Shared Hosted Desktops Dedicated Virtual Desktops
User
Customization
Shared Operating System (Win2003, Win2008),
Shared Applications: Means less management but
no per user customization. User can not control
workspace.
Every user has personal OS and
Applications: Per user customization possible
without much management. User can control
desktop and workspace.
Application
Support
Common applications works very well. Some
applications can not work: Apps which needs
admin rights, graphics intensive applications and
Multimedia applications.
Most applications are supported. Apps
requiring admin rights are ok. Most graphics
intensive applications and some multimedia
applications won’t work.
TCO Only Needs very simple infrastructure. Less
Capital expense. Administration is easy.
Needs bigger and complex infrastructure.
More administration and training needed.
Target Users Very good for common business users, using
common applications like MS Office, Business
Apps, Web portals, client server applications. Not
much useful for power users
Very good solution for full time desktop
users with resource demanding applications,
like developers, R&D, etc

7. Benefits of Shared Hosted Desktop
• Easy to Setup
– Requires only Microsoft Terminal Services and Terminal Services Management Solution
(Propalms TSE)
– Can start with a single hardware
• Based on standard, proven, well known and understood Microsoft Terminal
Services
• Requires least infrastructure
• Easy to Manage
– Its simpler to manage a Windows server than 10 products to implement dedicated virtual
desktops
• Choice to deliver just applications or full desktop
• Real Application/Data Centralization
– Unlike dedicated virtual/physical desktop, applications/data are not fragmanted
• Simple Application Deployment & Licensing
• Maximum utilization of server hardware resources
• Only few server license for AV, Backup solution etc. required

8. Any Special Reasons to Choose Dedicated
Virtual Desktops?
• Not all applications can be centralized with Terminal Servers
– Some applications can run only on Windows XP
– Some applications require administrative rights to run, e.g. custom apps,
trading application
– Resource intensive applications (Engineering and research applications)
• Power Users need dedicated desktop
– Power users like R&D engineers will need dedicated desktops where they
can do independent computing
• Migration from Windows XP to Windows 7 to Windows 8 to Windows
Blue ?
– Administration cost
– Loss of productivity: Profile migration
– Incompatible applications

9. Challenges with Dedicated Virtual Desktops
• Costly Affairs
• Most of the Physical desktop problems gets transferred to virtual
machine based desktops
• Need almost 6-7 products to build and manage such an
infrastructure
• Costly and more hardware required to setup
• Need expert to manage and maintain such a setup
• Data/Application is still fragmented across virtual machines
• Application licensing is a big challenge
• Same amount of endpoint security products required; Antivirus,
backup solution, etc.
