  1. Enterprise Computing Community - ECC 2010 Teaching Middle and High School Students about Enterprise Computing Neal Tanner, Marist College

  2. How can we teach kids about enterprise computing? • Avoid traditional enterprise computing examples (i.e. financial examples) • Relate it to topics they are interested in

  3. What are kids interested in that uses enterprise computing? • Current generation is an online one • Everything they do is online, even research for school (Google, Wikipedia) • Even entertainment has an online component

  4. What sort of entertainment? • Social mediums (IM, Twitter, Facebook) • Music and video (iTunes) • Games (Nintendo DS, X-Box Live)

  5. Which should we focus on? • Games are the most prevalent option • Many options available, for many different tastes • More committed gamers will have played more involved online fare (Call of Duty, World of Warcraft) • Casual gamers more likely to have played lighter online fare (Farmville, online card games)

  6. Which game do we focus on? • Massively Multiplayer Online Games (MMOGs) make the most use of enterprise computing • Popular MMOGs will be better documented and receive more attention • Older MMOGs will also be better documented • World of Warcraft is the current 800-pound gorilla, and is over 5 years old

  7. Why World of Warcraft? • It's immensely popular. 11.5 million subscribers worldwide • Available on Mac and PC • Available in 8 languages • Has received extensive coverage in numerous media outlets. • The CDC even used it for disease modeling

  8. What is World of Warcraft? • A Massively Multiplayer Online Game (MMOG) • Played in real time online, with many other players • Players divided into two factions, to allow for faction conflict • Large game world, spanning four continents

  18. Game Summary

  19. What is a realm? • A realm is World of Warcraft's answer to a game server. • Realms are actually a collection of multiple servers, called world servers • Each continent is its own world server • If a world server crashes, the continent and characters on it become inaccessible

  20. World Map

  21. Loading Screen – Boat or Zeppelin

  22. Loading Screen – Northrend

  23. Realms – continued • Some systems independent of world servers • Each character has access to a personal bank and a guild bank from every continent / world server • Three independent player-driven auction houses exist. • Two are faction specific, one is neutral. • This gives each character access to two separate auction houses from multiple continents

  24. Realms – continued • Players can have 10 characters per realm, 50 characters per account • Realms are organized into battlegroups • There are approximately 18 – 20 realms per battlegroup • In the US, there are 2 – 4 battlegroups per data center, and 4 data centers • Realms in the same battlegroup may participate in battlegrounds and dungeons together

  25. What about the data centers? • 10 data centers worldwide • 4 in the US – Washington, California, Texas, Massachusetts • 3 in Europe – France, Germany, Sweden • 3 in Asia – South Korea, China, Taiwan • Uses 20,000 systems, and 1.3 petabytes of storage • 13,250 server blades, 75,000 CPU cores, 112.5 terabytes of RAM

  26. What about other games? • Many games utilize the realm model, most with fewer features • Two other models exist • Instance-based • Node-based

  27. What is instance-based architecture? • Used primarily by Cryptic Studios for Champions Online and Star Trek Online • Each game region runs multiple copies of itself called instances • Champions Online has a maximum of 100 characters per instance • Star Trek Online has a maximum of 50 characters (ships) per instance

  28. What is node-based architecture? • Used primarily by Second Life and EVE Online • Each game region is a distinct node • Nodes in Second Life are called simulators • Each simulator has a 40 character (avatar) maximum • Each node in EVE Online is a star system. • Star systems have no maximum. Hundreds of characters (ships) in one star system at a time is not unusual

  29. Do any of these games use mainframes? • No, almost all use server blades • Servers are typically together in a clustered arrangement • One game, a space-based game similar to EVE Online, called Taikodom, developed by Hoplin Infotainment uses a zSeries mainframe

  30. Final Thoughts • Online games are not the only example of enterprise computing • But they may be the most interesting to kids • Any questions?
