3 Metrics of Success Project goals? Papers published? Technology transfer? Adoption of approach in the real world? Students produced? Marriages? Research results? Unexpected research results? All of the above?

4 NOW Finale Project Goals Fundamental change in how we design large- scale computing systems –snap together commodity components –self-managing, self-tuning, highly available Make the “killer network” real –realize the potential of emerging hardware technology –and push its effect through the rest of the system Integrated system on a building-wide scale –pool of resources (proc, disk mem) –remote processor and memory closer than local disk –federation of systems with local and global role The right way to build internet services
