    Infrastructure-as-a-Service (IaaS)
    Platform-as-a-Service (PaaS)

    Sold on demand, elastic, no managing required by user

  • 13. Critical Mass
    Who is Using this Cloud?
    Social networking sites
    500 million people using Facebook
    Webmail services like
    Hotmail and Yahoo mail
    Microblogging and blogging services such as Twitter and WordPress,
    Video-sharing sites like YouTube
    Picture-sharing sites such as Flickr,
    Document and applications sites like Google Docs, social-bookmarking sites like Delicious
    Business sites like eBay
    Rating and commenting sites such as Yelp and TripAdvisor.
  • 14. “By 2020, most people won't do their work with software running on a general-purpose PC. Instead, they will work in Internet-based applications such as Google Docs, and in applications run from smartphones. Aspiring application developers will develop for smartphone vendors and companies that provide Internet-based applications, because most innovative work will be done in that domain, instead of designing applications that run on a PC operating system.” (PewInternet, 2010)
  • 15. Why Change?
    It is easy and convenient
    Accessible from anywhere
    Information can be shared with anyone
    Information is not lost if computer crashes
    Decreased expenses for hardware
    Less dependency on IT professionals
    Private clouds eliminate security concerns
