Tony Sangha took PowerNSX (a set of PowerShell cmdlets for interacting with NSX) and created a tool to help document the NSX Distributed Firewall configuration. Servers/Hardware. Operating Systems/Applications. This tool exports the DFW configuration and then converts it into Excel format, and is available on GitHub.

Servers/Hardware. Vivek Gite over at nixCraft explains how to use ufw (Uncomplicated Firewall) on Ubuntu to limit SSH connections. Operating Systems/Applications. The post is a bit geeky but quite informative, and worth reading if SSH bastion hosts are a key part of your architecture. Read this post.)

Anthony Burke (disclaimer: Anthony works for VMware in the NSBU) has a post on how to use Python to automate the bulk creation of firewall rules for use with the VMware NSX distributed firewall. You may have heard about the “6-pack”, Facebook’s new open modular hardware switch introduced recently ( here’s a post on it ).

A discussion of “statefulness” brought me again to Ivan’s post on the spectrum of firewall statefulness. Servers/Hardware. Kenneth Hui, formerly of VCE and now with Rackspace, does a great job of explaining how VMware vSphere fits into the OpenStack Nova architecture in this blog post. Very good stuff!

I recently spoke at Interop 2016 in Las Vegas, and while I was there I scribbled down some notes pertaining to how decomposing applications into microservices-based architectures was similar in some respects to decomposing networks into an overlay network and an underlay (physical) network. Servers/Hardware. Networking.

With server virtualization, you can easily create, move, and delete virtual servers as needed, without the need for expensive hardware upgrades or complex reconfigurations. One of the key benefits of server virtualization is that it allows for more efficient use of hardware resources.

This post by Ranga Maddipudi shows you how to use App Firewall in conjunction with VXLAN logical networks. Next, Jason dives a bit deeper on the relationship between network overlays and hardware , and shares his thoughts on where it does—and doesn’t—make sense to have hardware terminating overlay tunnels.
