           •   Moving computing and data away from the desktop and the
               portable PC and simply displaying the results of computing that
               takes place in a centralized location and is then transmitted via the
               internet on the users screen.[Princeton University’s Center for
               Information Technology Policy]

           •   Using a thin client or other access point, like an iPhone,
               BlackBerry or laptop, users can reach into the cloud for resources
               as they need them. This network of servers and connections is
               collectively known as “the cloud”.

              The architecture
              The general architecture can be
               divided into two sections: The
               front-end and the back-end.

           •   The front-end
              This is the side of the
               computer user. It is what the
               client sees.

           •   The back-end
              The various servers and
               storage location systems that
               create the ‘cloud’ of computing
               services.

                Cloud Database: Stores all
                 clients’ data.

                The server: administers the
                 system, monitoring traffic
                 and client demands to
                 ensure everything runs
                 smoothly.

              Web applications
               (Webmail, Facebook, Twitter, YouTube, Flickr)



              Software as a service (Salesforce , Google Apps )

              Platform as a service (Google Co-op)

              Infrastructure as a service

              Cost savings:
               ◦ Hardware, software
               ◦ physical space
               ◦ Reduced ROI risk and uncertainty

              Ease and speed of deployment
               ◦ No testing phase
               ◦ Device and location independence

              Security and Privacy

              Customization

              Possession of computation
