The Winds of Change From January
Some quick thoughts on networking from my last couple of weeks at Networking Field Day 17 and Tech Field Day Extra at Cisco Live Europe:
- Cisco is in the middle of turning a big ship away from hardware. All their innovation is coming in the software side of the house. Big announcements around network assurance. It’s not enough any more to do the things. Now you need to prove they were done and show your work. Context and Intent only work if you can quantitatively show that they were applied.
- Containers are still a thing. Cisco has a new container platform. I also had the chance to chat with a startup called AppOrbit that’s doing some interesting things around containers but including storage and networking. They should be primed for some announcements soon, so stayed tuned for that!
- Automation is cool again. Well, maybe it never stopped being cool. But thanks to Extreme Networks and Juniper people are really hopping on the train to talk more about removing the limitations of the CLI and doing it with tools like Slack. Check out Lindsay Hill and Matt Oswalt showing this off to people in some finely crafted demos.

Video: What Is PowerNSX?
One of the beauties of VMware NSX is that it’s fully API-based – you can automate any aspect of it by writing a script (or using any of the network automation tools) that executes a series of well-defined (and well-documented) API calls.
To make that task even easier, VMware released PowerNSX, an open-source library of PowerShell commandlets that abstract the internal details of NSX API and give you an easy-to-use interface (assuming you use PowerShell as your automation tool).

AT&T’s dNOS Initiative Spotlights Fake News from Cisco (et al.)
One thing that’s clear from recent events is that the “alternative” path for network infrastructure refresh and build-outs – disaggregation – has just become exciting again due, in part, to AT&T’s recent announcement of the company’s dNOS (disaggregated Networking Operating System) initiative. Actually, prior to this proposal the fact that Pica8 and Cumulus – the only two pure open-standards-based NOS vendors in the market – combined have close to 2,000 current customers running on common hardware suggests that it’s been pretty exciting for some time now.
But AT&T’s new proposal does present us with a perfect opportunity to finally throw a bright spotlight on the palette of Fake News that has been tossed around the industry about disaggregated networking solutions and white-box networking in general. Of course, the elephant in the networking room is always Cisco, so let’s start there to see why AT&T pushed out this proposal in the first place.
Over the years, Cisco has successfully stared down any real threats to its account-control-plus-per-hardware-port-revenue business model, building itself up to the hegemony that it has today and, in the process, inadvertently laying waste to its customers’ ability to innovate in their own market segments based on differentiated network services.

5 Ways you can leverage the Linux community for your data center network
Here at Cumulus, we often talk about the benefits of having an operating system on Linux (if you need to be re-schooled on the benefits of unifying the stack, head here). But something that possibly goes overlooked, or at least under appreciated, is the value of the Linux community itself. The community is made up of 50,000 or so engineers all passionate about learning, improving and creating code. People like to say that when you go with a Linux operating system, you’re “standing on the shoulder of giants,” meaning that you don’t only have to rely on your inhouse engineering team (even if they’re world-class engineers), but rather you’re relying on thousands of engineers, including some of the absolute best in the business. Since Cumulus Linux runs on Linux, our customers have this community at their disposal. So why does that really matter? Here are five reasons to consider.
1. Security
The most widely cited benefit of having a community of 50,000 behind you is security. Basically it looks something like this. Let’s say you’re with a proprietary vendor (*cough* Cisco *cough* Juniper *cough*), and there is a glitch in your latest package installation causing a security vulnerability. Maybe Continue reading
