I’ve been following Cumulus Networks almost since its inception. The company was co-founded by J.R. Rivers, something of a legend in the networking space. Cumulus Networks’ raisan d’etre was to provide an open source operating system (eponymously called Cumulus Linux) that organizations could install on different networking hardware devices and, in doing so, gain all the benefits of software-defined networking (SDN) without any of the hassles of proprietary and locked-down software.
It was a compelling story (at least for this commentator). And given the credibility that Rivers bought to the table, I was sold.
