  2. What Would You PutInto A New College?

  3. Technology Use on Campus • Can be viewed as a “necessary utility”. • Computing technology is indispensible. • Requires a significant investment in: • Infrastructure • Personnel • Maintenance • Budget Source: http://www.compuscomputing.net

  4. Definitions • Thin Client: A student on your campus uses an inexpensive device using RDP protocol to communicate with centralized servers. • Virtual Client: A student, either on or off your campus, uses web-based access and RDP protocol to communicate with centralized servers.

  5. About “Thin Client” Computing • Use inexpensive “thin client” device or RDP (remote desktop protocol) • Communicate with a special server • All programs are run centrally on the special servers • Using Virtualization, multiple sessions (as many as 30 to 60) can run concurrently on a single server

  6. Back in the Olden Days…

  7. Back in the Olden Days…

  8. Decentralzied Desktop Computing For the past 20 years, desktop computing has been decentralized, meaning that all computing power was self-contained.

  9. Full Circle • Technology is now fast enough and cheap enough to make the centralized model cost-effective. • It’s better for security, for software licensing, and is much, much easier to maintain.

  10. How They Work…

  11. How It Works • Disk Images are created on the local SAN, or Storage Attached Network. • The programs run on the centralized blade server center. • It allows support to be mostly centralized • This reduces the time it takes to “image”, or prepare machines for class

  12. Thin Client Computing

  13. Thin Clients in Action

  14. A Thin-Client Computing Lab

  15. About “Virtual Client” Computing • All programs are run centrally on the special servers • Using Virtualization, multiple sessions (as many as 30 to 60) can run concurrently on a single server • Usually web-based • Perfect for distance learning • Perfect for bringing low-cost computing to remote locations

  16. And Now For Some Math

  17. The Cost Of Thin Client Computing * No tax, shipping, or handling was included in the calculations for this comparison.

  18. Building Out a New Center4 Computer Labs of 25 Seats Each • Assumptions: • Dell computers at $1,200 each • Devon IT thin clients at $138 each • Infrastructure (wiring, switches, servers) at $500 per seat • Servers (50 sessions per blade, no chassis costs included) • No remote software (VMWare) costs included • Virtual computing requires no labs

  19. Building Out a New Center4 Computer Labs of 25 Seats Each • More Benefits and Assumptions: • It would cost $45,000 per year to house a full-time technician at the new Center; Thin and virtual clients would be supported remotely. • With “Thin” or “Virtual” client infrastructure, students can access your software and systems remotely.

  20. Bringing “Free” ComputingTo the Community • Thin clients decrease your purchase and operations costs. • Virtual clients further decrease your purchase costs, and give you: • The ability to provide software to anyone, anywhere • The ability to provide lab experiences to people with their own computing resources • The ability to generate FTE and provide services where none existed before
