Why Cloud Computing Proper and affordable Accessibility

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)

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

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

Commercialization Public cloud Community cloud Hybrid cloud Private cloud Billed as a utility

…matching the clients needs.” (Rogers, 2003, p.368)

1. Assessing the need for change.2. Establish relationship with users.3. What’s wrong with the old way of doing it?4. Motivate and generate interest!5. Guided influence for change.6. Reinforce the message- we did this because..7. Shift clients to self-reliance roles (Rogers, 2003).

Critical MassWho 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.

“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)

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
