14 Tecnologia dei Servizi Grid e cloud computing - Lezione 001a 13 Definitions e-Science e-Science is used to describe computationally intensive science that is carried out in highly distributed network environments, or science that uses immense data sets that require grid computing; the term sometimes includes technologies that enable distributed collaboration (The term was created by John Taylor, the Director General of the United Kingdom's Office of Science and Technology in 1999 and was used to describe a large funding initiative starting in November 2000) e-Research e-Research extends e-Science and e-Infrastructure to all sciences and denotes the use of Information Technology to support existing and new forms of research. The main features are : Collaborative; uses GRID technologies; data intensive; and the adoption in research activities of a spectrum of advanced Information and Communication Technology (ICT) capabilities. It embraces new research methodologies emerging from increasing access to: Networks; Services; Tools.
