OK, now that I’ve mentioned Skydive, I can talk about this article that provides an example of functional SDN testing with Terraform and Skydive. Terraform is used to turn up OpenStack infrastructure, and Skydive (via connections into Neutron and OpenContrail, in this example) is used to validate SDN functionality. What’s that?

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.
