How is CC like water?

Its there when you need it.You dont think about it much.Cant/dont want to live without it.Computing without itIs like living in 1890...


Eniac Numerical Computer 1946Contained 17,468vacuum tubes, 7,200 crystal diodes, 1,500relays, 70,000resistors, 10,000 capacitorsand about 5 million hand-solderedjoints. It weighed over 30short tons(27 t), was roughly 8 by 3 by 100feet took up 1800 square feet and consumed 150kWof power.Shutdown in 1955.(Wikipedia, ENIAC)7CousinsMainframeBuilt to run reliably for decadesTransaction processingModern virtualized servers are mainframe computers

The goal is to make some uses of cloud computing easier for people who are not CS to use.11Want to See a Magic Trick?

Another flavor, called MapReduce made famous

A RabbitReally?!really_big_data_list x,y;for i is 1 to n doy[i] = f(x[i]);end;really_big_data_list x,y;y = map(f, x);

Potential Uses

Current Uses

EnablersLow-cost commodity computing & information technologyReduced operational cost (energy/people)Cloud computing vs. HPC16What is that?

Social IssuesAggregation of InformationAbuse of trustSecurity (Information) PrivacyIntellectual PropertyControlFreedom to chooseEnergy IssuesIn 2011, and average Google search used 0.3 watt-hrs of electricityGoogle data centers use 260 MW (2011) worldwide annuallyenough to power 200,000 homes in Richmond, VA or Irvine, CAOnly 2kWh per person

Our Own Doodoo ProblemWe create 2.5 exabytes (1018) of data every dayWe cant process it fast enoughWe cant move it fast enough

Digitally, we are drowning in data we cannot use.My vision for Cloud ComputingHigh-fidelity results
