Here's a trick question: how often do your Visio diagrams match what's really implemented in your network?
Wouldn't it be great to be able to create or modify them on-the-fly based on what's really configured in the network? That's exactly what Anthony Burke demonstrated in the PowerNSX part of PowerShell for Networking Engineers webinar (source code).

As part of the transition into my new role at Heptio (see here for more information), I had to select a new corporate laptop. Given that my last attempt at running Linux full-time was thwarted due primarily to work-specific collaboration issues that would no longer apply (see here), and given that other members of my team (the Field Engineering team) are also running Linux full-time, I thought I’d give it another go. Accordingly, I’ve started working on a Lenovo ThinkPad X1 Carbon (5th generation). Here are my thoughts on this laptop.
This is now my second non-Apple laptop in the last year. My previous non-Apple laptop, a Dell Latitude E7370, was a pretty decent laptop (see my review). As good as the E7370 was, though, the X1 Carbon is better.
The X1 Carbon features a dual-core i7 7500U CPU, which (subjectively, anyway) outperforms the mobile CPU in the E7370. This makes the X1 Carbon feel quite snappy and responsive. CPU performance was an issue for me with the Dell—it didn’t take much to tax that mobile CPU. I haven’t seen that issue so far with the X1 Carbon. Coupled with 16GB of RAM, the X1 Carbon is no Continue reading
If you’ve been tuning into Cumulus content lately, you probably know all about our initiative to bring S.O.U.L (Simple, Open, Untethered Linux) into networking — and for the uninitiated, feel free to check out our S.O.U.L page to learn all about the movement! It’s clear that our company and technology have S.O.U.L, but what does that look like in the office? Anyone who’s spent time at our office, in our bootcamps, with our people, etc. can feel that Cumulus Networks has “soul,” and this time we’re not talking about the acronym. We’ve got a passion, substance, life and feeling that pulses throughout our space like a funky bass line.
How do I know this? Well, I work at Cumulus, but it’s more than that. My former employers (before I started working at Cumulus Networks) are pretty varied, ranging from a restaurant to a university, but all of those jobs had one thing in common — they had no soul. To these Pink Floyd-ian businesses, employees were just cogs in the machine meant to forfeit passion for profit. Each day I dragged myself out of bed, drudged Continue reading
On April 4, 2018, over 80 individuals met in Ottawa and virtually via livestream for the first event in the Canadian Multistakeholder Process – Enhancing IoT Security series. Participants represented a wide-range of stakeholder groups, including government, academia, public interest, and industry representatives. Two Internet Society Organization Members, the Canadian Internet Registration Authority and CANARIE, as well as Innovation, Science and Economic Development Canada and the Canadian Internet Policy and Public Interest Clinic were partners for this event. IoT security is a complex issue that requires all stakeholders to cooperate and participate in the development of solutions, and we were pleased to have such truly multistakeholder representation.
The event kicked off with an interactive presentation from Larry Strickling, Executive Director of the Collaborative Governance Project. Strickling provided an overview of the multistakeholder process and facilitated a discussion among participants to determine ground rules and define what constitutes consensus. Participants, both those remote and in person, outlined over a dozen rules and three key metrics for determining consensus, which will be used throughout the entirety of the project.
In the morning, participants heard from a series of speakers who presented on IoT security and risk, the balance between IoT’s technological Continue reading
People think that big companies are too big to fail and thats why you should buy from big companies. Except that this is no longer true. To whit: HPE just divested all of its software assets. While HPE maintains a substantial interest in the new owner, I’m confident that HPE will walk away from those […]
The agreement between Alibaba Cloud and Esri will bring together engineers from both companies to deliver GIS innovations to the cloud.
Using a video analytics application, the operator was able to monitor and analyze a video feed of an assembly line and make real-time corrections.
Both firms continue to tout their broader cloud security platforms as superior to more focused efforts or those from large cloud providers.
Hyperconverged infrastructure in some ways is like the credit card in those old TV ads: in this case, it’s everywhere that enterprises want to be. HCI put compute and storage on the same cluster, tightly integrate them with networking and unified management tools and essentially give enterprises a private cloud for the datacenter as well as pushing compute out to the edges in a consistent manner.
HCI also promises a bunch of other things beneficial to enterprises, including streamlined management, lower costs, faster speeds, and easier scalability than traditional IT systems to better address the rise of cloud computing, analytics, …

The startup raised $6 million in its Series A round, bringing its total funding to $7.8 million. Axonize’s IoT orchestration platform is based on Microsoft Azure and is built for IoT service providers.
Last month, Docker turned five! In celebration of this milestone, we turned the spotlight on our amazing global community of customers, users, Community Leaders, Captains, mentors, partners and sponsors, and asked them to reflect on their Docker learning journey. Everyone came together to celebrate how far they had come, think about where they would like to go and take that next step towards reaching their goal.
We had a lot of fun during the #dockerbday with the Quebec #Docker community! Thanks to @ingeno for sponsoring the event, @tnazare for the cake and for being an awesome mentor! #dockerselfie #DockerQC pic.twitter.com/YZZNkWfWjq

There was an important development this month with the launch of Cloudflare’s new 1.1.1.1 DNS resolver service. This is a significant development for several reasons, but in particular it supports the new DNS-over-TLS and DNS-over-HTTPS protocols that allow for confidential DNS querying and response.
Why 1.1.1.1?
Before we get to that though, Cloudflare joins Google’s Public DNS that uses 8.8.8.8 and Quad9 DNS that uses 9.9.9.9, by implementing 1.1.1.1 as a memorable IP address for accessing its new DNS service. IP addresses are generally not as memorable as domain names, but you need access to a DNS server before you can resolve domain names to IP addresses, so configuring numbers is a necessity. And whilst a memorable IP address might be cool, it’s also proved important recently when DNS resolvers have been blocked or taken down, requiring devices to be pointed elsewhere.
The 1.1.1.1 address is part of the 1.1.1.0 – 1.1.1.255 public IP address range actually allocated to APNIC, one of the five Regional Internet Registries, but it has been randomly used as an address for Continue reading
Supercomputers keep getting faster, but they are keep getting more expensive. This is a problem, and it is one that is going to eventually affect every kind of computer until we get a new technology that is not based on CMOS chips.
The general budget and some of the feeds and speeds are out thanks to the requests for proposal for the “Frontier” and “El Capitan” supercomputers that will eventually be built for Oak Ridge National Laboratory and Lawrence Livermore National Laboratory. So now is a good time to take a look at not just the historical performance of capability …
