What is Cloud Computing?
  • Having secure access to applications and data from any network device
  • Computational resources accessible via a computer network, rather than from a local computer
  • Any computer connected to the internet has access to your files and applications.
  • Instead of carrying around a storage medium such as a flash drive or DVD, users can access personal files such as music, pictures, videos, book marks and even play games or preform word processing functions on a remote server
    • Remote server- allows a user to log on to the network from a distant location

How it Works

History
  • Underlying concept and idea for computation as a public utility dates back to the 1960s and John McCarthy
  • Term “cloud” is a metaphor to represent the abstraction of the internet and based on the cloud drawing
  • Was referenced in a scholarly way in 1997 that computing was evolving from a main-frame-based structure to a network-based architecture
  • Amazon started developing the idea further with Amazon Web Service (AWS) in 2006
  • Exposure of cloud computing to public media was in 2006 by Google Ex CEO Eric Schmidt

Types of Cloud Computing
  • Public Cloud
    • Traditional, mainstream cloud computing available to everyone
    • Offered on a self-serve basis over the internet
  • Community Cloud
    • Used when similar organizations seek the same infrastructure and requirements
    • Offers more security
  • Hybrid Cloud and Hybrid IT Delivery
    • Offer IT services to manage the performance, security, ad privacy
    • Useful for archiving and backup functions
  • Combined Cloud
    • Some is information is private and only accessible to certain people within the company
    • Some is available to the public
Pros
  • Cost- software and computing capabilities are publicly available
  • Don’t have to worry about which computer has your files if you use multiple computers
  • Device and location independence- allows users to access their information anywhere with internet access.
  • Reliability- don't have to worry about performance or it crashing
  • Maintenance- no installation or upgrades
  • Storage- it stored virtually and archived
Cons
  • Privacy- companies hosting the cloud service can monitor your information
  • Compliance- coining the term and using it as a trademark
  • Data Usage- has to be downloaded each time for use onto that computer
  • Criticism of the term- too unspecific and misleading (watch YouTube video below and see some of the comments about criticism on cloud computing)
    • CEO of Oracle Corporation Larry Ellison “cloud computing is everything that we already do”
    • Marketing scheme, marketing hype campaign (see video below)




Use in Education
  • Allows students to access information from anywhere, not just school
  • Reduces costs for schools and students when purchasing educational software
  • Great way to backup files
  • Less dependence on IT for software updates and installation
  • Possibilities are endless
