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, JCR Licklider; also 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

Affordability
11. Late Entry Users
Fear of new innovation
Fear of technology
Fear of the unknown

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.
Whats wrong with the old way of doing it?
Motivate and generate interest!
Guided influence for change.

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
