  3. "What is Cloud Computing?" - Liam (2 weeks ago)

  4. "The concept, quite simply, is that vast computing resources will reside somewhere out there in the ether (rather than in your computer room) and we'll connect to them and use them as needed." "Cloud computing is a buzzword..." - Jonathan Weber (The Times Online) http://go.bath.ac.uk/xpcb

  5. 3 aspects of Cloud Computing As described by Thorsten vok Eiken at RightScale: •  Applications in the Cloud (SaaS): • Google Apps • Flickr •   Platforms in the Cloud (PaaS): • Google App Engine • Mosso • Force.com • Infrastructure in the Cloud (HaaS) • Amazon Web Services http://go.bath.ac.uk/ym2i  http://go.bath.ac.uk/kzkz
