Microsegmentation like that provided by vendors CISCO and VMware state that traditional perimeter defenses akin to medieval castles walls no longer work. The problem is that threat actors are able to get through the castle gates (firewalls) and once in, are able to evade the castle guards (IPS). It enables Internet at Scale.

At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. I recently came across a couple useful troubleshooting guides, one for Open vSwitch (OVS) and OpenStack Neutron and one for VMware NSX. Have fun reading! Networking. It’s a pretty interesting read, in my opinion.

Thinking of using a hardware VTEP (VXLAN Tunnel Endpoint) with VMware NSX? VMware recently announced Open Hardware Management Services (OHMS) , a project intended to help manage servers and switches in a software-defined data center (SDDC) context. Rajdeep Dua has written an overview of the architecture of SwarmKit. Version 2.0

I highly recommend you read the entire post, but in short the five skills Matt recommends are software skills (which includes configuration management and software development tools like Git ), Linux, deep protocol knowledge, hypervisor and container networking, and IPv6. What does this mean? Servers/Hardware.

Verplanke believes that DPDK (Data Plane Development Kit) and virtualization are key to virtualizing workloads that move around lots and lots of packets, such as firewalls, routers, and other similar functions. In recent years, we’ve seen more devices running off-the-shelf software (like Linux).

A discussion of “statefulness” brought me again to Ivan’s post on the spectrum of firewall statefulness. VMware introduced VMware NSX recently at VMworld 2013. I found a few articles by fellow VCDX Josh Odgers that discuss the impact of Nutanix’s converged architecture on vSphere designs.

specifically, the new container network firewall functionality. When I was using Fedora, I needed some useful information on firewall-cmd , and found this article to be helpful. For what it’s worth, I’ve never tried NetBSD, but I have yet to run into any similar issues with any distribution of Linux I’ve tried.
Expert insights. Personalized for you.
