At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. Matt Oswalt recently unveiled (and open sourced) a framework called ToDD, which stands for “Testing on Demand: Distributed”. You may also find this (related) article on memory inside Linux containers to be helpful.

It is important to use security tooling such as OpenSCAP, the open source version of the Security Content Automation Protocol, to harden virtual machine images prior to their deployment in virtual private clouds. These policies, like any firewall, provide an invaluable means of limiting attack vectors both inside and outside the VPC.

Jason Edelman has posted a self-compiled list of networking projects that are open source ; this is a useful list, so thanks for compiling it Jason! I didn’t think that OpenFlow itself was actually open source (even though there are multiple open source implementations of various OpenFlow products).
