  • Moving to the cloud means no more trying to remember whether you left the latest version of your life story on the desktop or the laptop. No more backing up everything to a thumb drive to move it from one device to another. No more copying all your stuff from one PC to another when you buy a new one. It also means you can create a repository of information that stays with you and keeps growing as long as you are alive.

    • Google Maps
    • Online Banking
    • Tracking Investments
    • Etc.

    • Web 2.0
  • 4. Cloud Computing - Definitions
    • ... the trend toward online services that run in a Web browser and store users’ information in a provider’s data center
    • - Princeton University
    • Workshop Announcement
  • 5. Cloud Computing - Definitions . . . the idea of relying on Web-based applications and storing data in the “cloud” of the Internet - MIT Technology Review
  • 6. Cloud Computing - Definitions . . . a computing paradigm shift where computing is moved away from personal computers or an individual application server to a “cloud” of computers - Wikipedia
  • 7. Cloud Computing - Definitions It starts with the premise that the data services and architecture should be on servers. We call it cloud computing – they should be in a cloud somewhere - Eric Schmidt CEO, Google
  • 8. Cloud Computing - Definitions
    • ... moving computing and data away from the desktop and the portable PC and simply displaying the results of computing that takes place in a centralized location and is then transmitted via the Internet to the user’s screen
    • - John Markoff
    • New York Times
  • 9. Location, Location, Location
    • Possession implies control
    • Control implies power
  • 10. Location, Location, Location
    • In the history of computing, we’ve moved from computing in centralized locations to computing in decentralized locations
    • Mainframes  Desktops and Laptops
    • Centralized  Distributed
  • 11. Location, Location, Location
    • Mainframes 
    • - High Cost
    • - Centralized Control
    • - Expert Management
    Desktops and Laptops - Low Cost - User Autonomy - Technical Wasteland Cloud Computing - Low Cost (so far) - Shared Responsibility - Expert Management
  • 12. Cloud Computing
    • Pros
      • Access via the Internet from anywhere
      • Platform independent (Windows, Mac, Linux, etc.)
      • No need to backup
      • No need to transfer files between computers
      • Maintenance by the provider
      • Free (or monthly payment) ‏
      • Automatic,transparent and painless upgrading
      • Ability to share data with others (collaborate)
  • 13. Cloud Computing
    • Cons
      • Downtime problems
        • Dear User: We're sorry for the three-month service outage
        • Uh Oh! The net's down again
      • Security problems
        • Dear User: We apologize if your confidential information was exposed during our recent maintenance period
  • 14. Cloud Computing
    • The first wave was the transition from email clients, such as Outlook Express and Juno to Web-based services, such as Gmail, HotMail or MobileMe
    • The second phase involved storing and transferring data using remote servers
    • The third phase is pushing applications, such as word processors, spreadsheets and news readers, to the cloud
  • 15. Cloud Computing
    • Today, you can do almost anything you want without buying software or using anything other than your browser

  • 26. Some Questions to ask about Cloud Computing
    • Does the data center that is housing the servers have physical security 24/7?
    • Who has permission to access these servers?
    • What is the down-time history of the host?
    • Is the application 100% Web-based?
  • 27. 10 Questions to ask about Cloud Computing
    • Is the vendor experienced in both the execution and hosting of the application?
    • Does the vendor provide timely and free upgrades?
    • Is the backup strategy adequate (at minimum nightly on-site and weekly off-site)?
    • What technical support is available?
  • 28. Paul Maritz of VMWare, a leader in providing cloud computing applications says,
    • “ From the consumer point of view, ultimately the user wants his information to belong to him and not to any particular device.
    • “ Increasingly, individuals are characterized by a body of digital information. And that information needs to live on over a period of decades—the rest of our lives—beyond the lifetime of any particular device you might have.
  • 29. Paul Maritz of VMWare, a leader in providing cloud computing applications says,
    • “ So everybody is going to need somebody to be the custodian of their information. Just like we don't put our money under the mattress anymore, we put it in the bank, so most of us will become customers of an ‘information bank’ and in so doing we will become dependent on the cloud.”
  • 30. Week in Review, New York Times, Sunday, July 12th
    • Much of the computer world is inexorably moving toward “cloud computing,” in a shift that could greatly simplify the way we access and process digital information.
  • 31. Week in Review, New York Times, Sunday, July 12th
    • There would be no more pesky software installations, no more trudging through menu after menu to configure programs, no more backups or upgrades. E-mailing bulky attachments would be a thing of the past, as people could allow others to access their files online, making collaboration easier.
  • 32. Week in Review, New York Times, Sunday, July 12th
    • Any device, anywhere — from a desktop PC to a mobile phone — could give users instant access to all their files and programs so long as it had a Web browser.
