  1. Cloud Computing Diffusion of Innovations Diane Burling Walden University EDUC 8841 Diffusion and Integration of Technology in Education Fall 2010

  2. Why Cloud Computing • Proper and affordable • Accessibility

  3. Need • Sold on demand, typically by the minute or the hour; • Elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access)

  4. Research • Dates back to 1960, computer scientist John Mccarthy • 2.Internet hosting services expand on what is already in place- provide hosting services: • Infrastructure-as-a-Service (IaaS) • Platform-as-a-Service (PaaS) • Software-as-a-Service (SaaS). • Sold on demand, elastic, no managing required by user

  5. Development • Privacy Issues • Compliance • Legal • Open source/standards • Security • Availability/performance • Sustainability • Clients

  6. Commercialization • Public cloud • Community cloud • Hybrid cloud • Private cloud • Billed as a utility

  7. Phases of Innovation

  8. Phases continued Phases…

  9. S-Curve Cloud Computing Diffusion Implementation Idea 1960 1990 2000 2010

  10. Innovators & Early Adopters • IT Professionals • Ease of Use & Implementation • No upgrade of equipment • Use what is needed • Accessibility • Affordability

  11. Late Entry Users • Fear of new innovation • Fear of technology • Fear of the unknown… • Training and support • Hands on help by IT and Super-Users

  12. Key Change Agents “Facilitating the flow of innovations … …matching the clients needs.” (Rogers, 2003, p.368) • Assessing the need for change. • Establish relationship with users. • What’s wrong with the old way of doing it? • Motivate and generate interest! • Guided influence for change. • Reinforce the message- we did this because.. • Shift clients to self-reliance roles (Rogers, 2003).

  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
