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
`

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
Server Based Computing Solutions
Shared Hosted Desktops (SHD) based on Microsoft Terminal
Services
Dedicated Virtual Desktops (DVD) based on Hypervisor Technology
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

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
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
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.
