Back in October 2015, I spoke at All Things Open in Raleigh, North Carolina, an event focused on open technology and open source software. I was very excited by this event because many attendees work in or manage data centers, which means they are very familiar with Linux but have little experience with the networking stack. Cumulus Networks is the first major networking company to contribute a true Linux networking operating system for data center switches, which is highly disruptive to the industry and drives a lot of fun conversations with open-minded individuals.
