  3. Why all the hubbub?

  4. Why all the hubbub? • The IT industry loves and lives on buzz words and acronyms • SLAs, ROIs, MTBFs, Mbps, the list goes on and on… • So many, some have to be ‘repurposed’ • Business pressure to contain costs • Equipment costs • Power costs • Cooling costs • Real Estate costs • Personnel costs Photo courtesy unixnewbie.org

  5. What is ‘The Cloud’?

  6. What is ‘The Cloud’? • Ten years ago, ‘The Cloud’ = ‘The Internet’ • Now: ‘The delivery of computing as a service, rather than a product’ (Wikipedia) • Grid Computing = Utility, ‘Always On’ • Depends on who’s defining it • External, Internal • SaaS, PaaS, IaaS • Amazon EC2 • Google Docs, Office 365 • DropBox, iCloud • FaceBook, Twitter • NOT ‘The Matrix’…yet… Image courtesy FiberLink Communication

  10. Pros and Cons • Pros: • Quickly, easily, cheaply scalable • Quickly, easily, cheaply upgradeable • ‘Green’-ish Technology • Disaster Recovery (DR) • Pilot Projects • Short term • Cons • Where’s your Data? • Who’s got your Data? • What happened to your Data? • The Internet is Down… • More Eggs in One Basket • Anonymous must Die!

  11. What does it mean?
