What is VDI? Rebirth of the dumb
terminal Striped down client
◦ PC with pretty much just Windows and some drivers
◦ Thin Client Appliance
◦ And a Bunch of Servers
Opportunity to reduce cost Increased efficiency, reliability, and
productivity Supports Disaster Recovery Supports Business Continuity Standardization Reduced hardware refresh cycles
Why Do VDI?
Started with a Pilot (June 2009)◦ 16 staff – including several managers
Implemented as Shared Service Today we have about 116 deployed
Implementation
Citrix XenDesktop◦ Standard Windows Configuration◦ MS Office◦ Antivirus◦ Device Drivers
Citrix XenApp ◦ Special Apps – (MS Project, Visio, STAR …)
Appsense◦ Personalization Software◦ Keeps folks look and feel
Wyse Thin Clients
Washington Configuration
Support is much easier Standardization Available anywhere there is a good network
connection Almost any device will work Reduces/eliminated the refresh cycles Ease of deploying patches Ease of updating or deploying new software
Advantages
Bandwidth Gets blamed for everything Requires techs to clear things at the server
on occasion Upfront Cost does not save money When you are dead you are really dead
