Automating Brownfield Environments (Using an 802.1x Example)
This is a guest blog post by Albert Siersema, senior network and cloud engineer at Mediacaster.nl. He’s always busy broadening his horizons and helping his customers in (re)designing and automating their infrastructure deployment and management.
This is the second post in a series focused primarily on brownfield automation principles using 802.1x deployments as an example (you might want to read part 1 first).
Before diving into the specifics of the next 802.1x automation phase, let’s take a step back and think about why we’re going through this effort. Automation is a wonderful tool, but it’s not a goal… and neither is 802.1x a goal - it’s just another tool that can help us realize business benefits like:

An open-source benchmark suite for microservices and their hardware-software implications for cloud & edge systems Gan et al., ASPLOS’19
Microservices are well known for producing ‘death star’ interaction diagrams like those shown below, where each point on the circumference represents an individual service, and the lines between them represent interactions.
Systems built with lots of microservices have different operational characteristics to those built from a small number of monoliths, we’d like to study and better understand those differences. That’s where ‘DeathStarBench’ comes in: a suite of five different microservices-based applications (one of which, a drone coordination platform called Swarm has two variations – one doing most compute in the cloud, and one offloading as much as possible to the edge). It’s a pretty impressive effort to pull together and make available in open source (not yet available as I write this) such a suite, and I’m sure explains much of the long list of 24 authors on this paper.
The suite is built using popular OSS applications and representative technologies, deliberately using a mix of languages (C/C++, Java, Javascript, node.js, Python, Ruby, Go, Scala, …) and both RESTful and RPC (Thrift, gRPC) style service interfaces. There’s a nice Continue reading
Welcome to Speed Week!
Every year, we celebrate Cloudflare’s birthday in September when we announce the products we’re releasing to help make the Internet better for everyone. We’re always building new and innovative products throughout the year, and having to pick five announcements for just one week of the year is always challenging. Last year we brought back Crypto Week where we shared new cryptography technologies we’re supporting and helping advance to help build a more secure Internet.
Today I’m thrilled to announce we are launching our first-ever Speed Week and we want to showcase some of the things that we’re obsessed with to make the Internet faster for everyone.
How much faster is faster?
When we built the software stack that runs our network, we knew that both security and speed are important to our customers, and they should never have to compromise one for the other. All of the products we’re announcing this week will help our customers have a better experience on the Internet with as much as a 50% improvement in page load times for websites, getting the most out of HTTP/2’s features (while only lifting a finger to click the button that enables them), finding the optimal route across Continue reading

The Linux Migration: Preparing for the Migration
As far back as 2012, I was already thinking about migrating away from Mac OS X (now known as macOS). While the migration didn’t start in earnest until late 2016, a fair amount of work happened in advance of the migration. Since I’ve had a number of folks ask me about migrating to Linux, I thought I’d supplement my Linux migration series with a “prequel” about some of the work that happened to prepare for the migration.
In the end—and I imagine some folks may get upset or offended at this—an operating system (OS) is really just a vehicle to deliver applications to the user. While users like myself have strong preferences about their OS and how their OS works, ultimately it is the ability to “get things done” that really matters. This is why I ended up suspending my Linux migration in August 2017; I didn’t have access to the applications I needed in order to do what I needed to do. (Though, to be fair, part of that was a lack of growth on my part, though that’s a different blog post for a different day.)
To that end, most of the work I did in Continue reading
Worth Reading: Nothing Fails Like Success
I hope I'm still allowed to quote a paragraph from someone else's article (thank you, EU, you did a great job). Here's what Jeffrey Zeldman wrote about startup business models:
A family buys a house they can’t afford. They can’t make their monthly mortgage payments, so they borrow money from the Mob. Now they’re in debt to the bank and the Mob, live in fear of losing their home, and must do whatever their creditors tell them to do.
Read the article and think about how it applies to unicorn-based networking technologies ;)
Vortex Race3 Key Remap
I recently purchased the Vortex Race3 mechanical keyboard. I really love this keyboard, it has Cherry MX brown switches with 4 layers of arbitrary key programming. I like this board because its almost as compact as a 60% keyboard but has almost the same number of keys as a ten key less...Vortex Race3 Key Remap

We started working with Microsoft five years ago to containerize Windows Server applications. Today, many of our enterprise customers run Windows containers in production. We’ve seen customers containerize everything from 15 year old Windows .NET 1.1 applications to new ASP.NET applications.
If you haven’t started containerizing Windows applications and running them in production, here are five great reasons to get started:
1. It’s time to retire Windows Server 2008
Extended Support ends in January 2020. Rewriting hundreds of legacy applications to run on Windows Server 2016 or 2019 is a ridiculously expensive and time-consuming headache, so you’ll need to find a better way — and that’s Docker Enterprise.
2. It’s much easier than you think to containerize legacy Windows apps
You can containerize legacy Windows applications with Docker Enterprise without needing to rewrite them. Once containerized, these applications are easier to modernize and extend with new services.
3. Both Swarm and Kubernetes will support Windows nodes
The recently announced Kubernetes 1.14 includes support for Windows nodes. With Docker Enterprise, you will soon be able to use either orchestrator to run Windows nodes.
4. Your Windows apps become fully portable to the cloud
Once you Continue reading

Introducing The Internet Society Accessibility Special Interest Group
An ordinary day on 9th April 2019 was turned in to an extraordinary one, as our efforts bore fruit and we finally succeeded in chartering the Internet Society Special Interest Group on Accessibility. The Internet Society Accessibility Special Interest Group or ISOC Accessibility SIG/ISOC A11y SIG is intended to serve persons with disabilities to ensure the Internet and digital domain is for everyone.
Over 1.3 billion people worldwide – about 15% of the world’s population – experience some form of disability. The Accessibility SIG, with a people-centric approach, is aimed at providing interested participants a platform to discuss the Internet-related accessibility issues faced by the people with disabilities and to try to find the solutions to those issues. It also aims to provide a collective voice to a community that the UN calls the world’s largest minority.
The SIG also represents a journey for all of us who are members and who are dedicated to creating equal access to the Internet for everyone regardless of disability. The journey at the Internet Society started with the establishment of the ISOC Disability and Special Needs Chapter in 2002. Along the way, many dedicated and tireless workers, like the late Cynthia Waddell Continue reading
