  • on-demand self-service, broad network access, resource pooling, rapid elasticity or expansion, and measured service.
  • • Cloud computing systems generally have a front end, which is what the user sees, and a back end, which does all the work.
  • All three service models allow users to run applications and store data online; Each offers, however, a different level of user flexibility and control When you drive a car you : Decide where to go Pay for the car Do the driving; take care of parking (i.e., storage) Pay for gas and maintenance When you rent a car: You decide where to go You pay for the time/gas/parking/etc. you use the car You do the driving (unless you hire a driver as well); take care of parking (i.e., storage) Someone else pays for the maintenance/provides long-term storage When you opt for a taxi ride: You decide where to go You pay only for the miles you travel Someone else drives/takes care of parking (i.e., storage) Someone else purchases the vehicle
  • All three service models allow users to run applications and store data online; Each offers, however, a different level of user flexibility and control SaaS  allows users to run existing online applications  applications/software Google Docs, Zoho, Microsoft Office Web Apps PaaS  allows users to create their own cloud applications, using supplier-specific tools and language  middleware [e.g., Heroku (acquired by force.com) is a PaaS for Facebook apps creation // use PaaS to launch their own Cloud SaaS.] IaaS  Allows users to run any applications they please on cloud hardware of their own choice  servers, routers, network eqt, firewalls [e.g., Are you aware of Farmville and Mafia Wars? Yes, these are the most popular Facebook games created by Zynga.com . It has more than 230 million monthly users run more than 12000 servers on Amazon AWS . When they launch a new game, they start with a few servers and then ramp up their capacity in real time. (pay for what you use on an as need basis-- configure resources as needed)

    6. 6. Cloud Computing is….CC Image Courtesy of lennysan: ‘Some clouds for you http://www.flickr.com/photos/lennysan/4404460348
    7. 7. National Institute of Standards & Technology [NIST] says…a model for enabling ubiquitous, 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
    8. 8. Wikipedia says…the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically the Internet)
    9. 9. Encyclopædia Britannica says… method of running application software and storing related data in central computer systems and providing customers or other users access to them through the Internet."cloud computing." Encyclopædia Britannica. Encyclopædia Britannica Online Library Edition. Encyclopædia Britannica, Inc., 2012. Web. 28 Feb. 2012. http://library.eb.com/eb/article-9474374>.
    10. 10. Anna says …In the most basic sense, cloud computing means (especially for people like you and me) using a web browser for our computer needs – software applications – data storage – computing power – platform for application building

    33. 33. The Advantages• Convenience – Access (devices, between computers) – Internet-based• Free (or based on use)• No installation• Reliability  Back up• Improved security• Short learning curve
    34. 34. The Advantages, continued• “Painless” upgrading• Easily share information/data• Mac? PC? Linux? Doesn’t matter!• It just works (i.e., maintenance? Not your problem)
    35. 35. The Downside• No Internet? Rut-roh!!!!• Long-term costs – Upgrade to ad-free option – Large amount of data storage needed• Hackers (i.e., security of data)• Privacy• Company goes belly up or merges – Let me tell you a story about delicious, Picnik, etc.
    36. 36. The Downside, continued• Features may be limited – e.g., PhotoShop Express is a “lite” version of Photoshop, same for the Office Web Word App• Software may run slow• Loss of stored data – Unless you’ve backed up files to your PC, external hard drive, etc.
    37. 37. The Impact• More mobile• Increases shareability• Facilitates collaboration• Access to “software”• Exposure to services/software• Choices (buy, “lease,” or freebie)
