Lunch+and+Learn+-+Desktop+Virtualization

Mark Crescenzi from Prismworks
 * 2 competing technologies - Citrix and VMWare
 * standardizing and consolidating
 * more flexible
 * security
 * Problem with desktops - keeping them updated
 * Study - each desktop costs 4,000-8,000 to continually maintain (probably not that much in education environment)
 * VDI - Virtual Desktop Infrastructure
 * Image per user so you moved maintaining image from desktop to server
 * Degraded user experience and higher storage costs
 * Types of Users (3 core groups)
 * Administration
 * Teachers
 * Students - Repetive task-based workers
 * Virtual Desktops are not for everyone
 * Newer Generation Virtual Desktop
 * Separate applications from Desktops
 * Hosted or streamed apps for desktops (virtual or physical)
 * Application runs independent of desktop
 * Application Virtualization
 * Novell - Zen Application Virtualization
 * Microsoft - App-V
 * Citrix - Streamed Apps
 * Patch and update each application in isolation
 * reduce storage costs
 * Application access control (who can run them) and license metering
 * So only some desktop images for physical requirements but then for everything else - Apps on Demand
 * No installation - already installed and encapsulated
 * Simple master image of each component
 * have a master application that is encapsulated
 * User settings
 * Can install applications with specific java version that works with that application
 * For example:
 * One image for K-5, when they log in, a folder opens with all their applications,
 * Management of it?
 * Skill set - similar concept of ghost api
 * What about using wireless and streaming apps - (bandwidth)
 * When you first click on app, it pulls it down to computer
 * What happens if 4 classrooms with 30 students on one access point tries to get app? - (not an issue?)
 * Hosted Applications (another way to move towards single image/separate apps)
 * Separating apps minimizes desktop image sprawl
 * **Any vendor that says something doesn't work with server virtualization - tell VM and they will make sure it becomes certified**
 * If you have an OEM license of Windows, this cannot be virtualized
 * Virus protection for each session - not just the server
 * At any one time, only 40-50% of pcs are actually being used
 * Licensing is concurrent users
 * Comments:
 * WCUT should look at virtualization for better delivery of applications/information via the WAN
 * Have real-world demonstrations on how virtualization can be used in school environment
