Investigating big data technology in my job also means observing the revolution in networking technology as the mean for transporting the data. For years, the networking spaces were dominated by just a number of players, i.e. Cisco, Juniper, etc. I was so surprised looking at disruptive innovators such as Cumulus Linux which offers independent network operating system atop bare metal (“unbranded”) switches. Their slide about low margin proposition reminds me of Christensen’s Innovator’s Dilemma: new entrants beat the established ones in the markets with low margins (attack from below). Sooner or later the revolution will take place.
