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

Washington VDI Config

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
