2 What will the issues be in 2025? Cyberinfrastructure ± aka Grid computing ± NSF Vision for next era of computing ± integrated suite of computational engines, mass storage, networks, digital libraries and databases, sensors, software and services ” (NSF, 2003). ± Can include human users and the user interface ± NSF (2003) Revolutionizing Science and Engineering Through Cyberinfrastructure: Report of the National Science Foundation Blue- Ribbon Advisory Panel on Cyberinfrastructure : Atkins report. Computing on the grid • Services available on demand • Independence of source •“The computer is the network” • Cloud computing •Virtual organizations Geospatial elements of the GRID: Sensor webs
