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).

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.

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.
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

The platform is different from Docker in that it's focused on workloads and not microservices.
It manages any device in a campus or branch office that needs network access, the company claims.
The company expects to maintain business from its largest customer — CenturyLink.
Goals and outcomes change. ITIL-centric projects do not.
