A little perspective
In September 1956 IBM launched the 305 RAMAC, the first computer with a hard disk drive (HDD). The HDD weighed over a ton and stored 5MB of
data....

What is Cloud Computing?
•Cloud computing is still an evolving paradigm.
•Its definitions, use cases, underlying technologies, issues, risks, and benefits will be refined in a spirited debate by the public and private sectors.

Cloud Computing: a definitionCloud computing is a model for enabling
convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. (National Institute for Standards & Technology)

Service Layers of Cloud Computing• Top Layer: Software as a Service (SaaS) - Google
Apps• Middle Layer: Platform as a Service (PaaS) –Web Server and the programming environment.• Lowest Layer: Infrastructure as a Service (IaaS)
– Means of delivering basic storage an computing capabilities as standardized services. The pooling of servers, storage systems, switches, and routers.

• Easier for application vendors to reach new customers.
• Delivering & supporting applications is easier and cost effective.
• Using commodity server & storage hardware costs less.
• Driving down data center operational costs saves money.
Water Powered Computers
Data centers need electricity. The U.S. EPA estimates that U.S. servers and data centers were responsible for a total of 1.5 percent of America's electricity consumption in 2006 (about 61 billion kilowatt-hours), at a cost of $4.5 billion, and that their consumption will double by 2011.

Water Powered Computers
Cheap electricity can be found in hydroelectric dams that dot the Rockies and the Northwest.
Washington and Oregon, America's top two hydroelectric producing states, have electricity costs 20 to 30 percent lower than the national average.

Google’s Servers to go
Shipping containersGoogle’s data centers are composed of standard 1AAA shipping containers packed with 1,160 servers each, with many containers in each data center. Credit: http://news.cnet.com/8301-1001_3-10209580-92.html
What could possibly go wrong?•downtime•data breaches•court-ordered shutdown as a result of patent infringement
• liability for copyright-infringing or other illegal material
• liability for sending spam
Pew Internet & American Life Project
Overall, 69% of online users have done at least one of these six activities

Pew Internet & American Life ProjectReasons for using the cloud
• 51% say a major reason is that it is easy and convenient.
• 41% say they like being able to access their data from whatever computer they are using.
• 39% cite the ease of sharing information.

Pew Internet & American Life ProjectReasons for Concern
• 90% of cloud application users say they would be very concerned if their data were to be sold to another party.
• 80% say they would be very concerned if companies used their photos or other data in marketing campaigns.
• 68% of users of at least one of the six cloud applications say they would be very concerned if companies who provided these services analyzed their information and then displayed ads to them based on their actions.

Horizon Report• Produced by the New Media Consortium
(NMC) and Educause.
• This report centers on the applications of emerging technologies to teaching, learning, research, or creative expression.
The Horizon Report –Extensive Report on applications to education
• Math applications- students can turn their I-phones into graphing calculators
• Science applications- virtual labs • Language applications- peer review
documents • Productivity applications- platform free• Music- instrument simulators
