The project can finally shed itself of the (unfair) claims that the governance under Nicira (and later VMware) wasn’t “open enough.” For more information, refer to the official Linux Foundation press release.

It was good to read this post on Cumulus Linux first impressions by Jeremy Stretch. I’m a fan of Cumulus, but I’m admittedly a Linux guy (see here ) so you might say I’m a bit biased. Jeremy is a “hard-core” networking professional, and so hearing his feedback on Cumulus Linux was, in my opinion, useful.
