The Grid: The Web on Steroids On-demand creation of powerful virtual computing systems Web: Uniform access to HTML documents Grid: Flexible, high-perf access to all significant resources Sensor nets Data archives Computers Software catalogs Colleagues Ian Foster

Network Exponentials F Network vs. computer performance –Computer speed doubles every 18 months –Network speed doubles every 9 months –Difference = order of magnitude per 5 years F 1986 to 2000 –Computers: x 500 –Networks: x 340,000 F 2001 to 2010 –Computers: x 60 –Networks: x 4000 Moores Law vs. storage improvements vs. optical improvements.
