The Matrix-like control that Nicira offers should also make the Internet more reliable. After the Fukushima-Daichi nuclear disaster in Japan last March, electricity rationing and scarce supplies of diesel for generators trapped some Web services offline in powerless data centers. Last August NTT showed that Nicira's technology could have kept those systems active by moving them rapidly elsewhere. In tests, software was smoothly transferred between data centers 30 miles apart without even having to stop the programs from running. Even as NTT's software moved to new physical hardware, Nicira's technology maintained the illusion that nothing had changed. "We can move like liquid between data centers ahead of brownouts," says Casado. Making such transfers without Nicira's technology would mean laboriously reprogramming network hardware and turning off the system being protected from the brownout.
