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:

Welcome to Speed Week!

Welcome to Speed Week!
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

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...

Heavy Networking 448: An Inside Look At What’s New In Juniper’s Contrail SD-WAN (Sponsored)

Today's Heavy Networking podcast is a sponsored conversation with Juniper Networks on what's new in its Contrail SD-WAN, including a cloud-managed option. We also examine competitive differentiators such as scale, and how Juniper is integrating Mist with Contrail SD-WAN to enable SD-Branch.

Supermicro moves production from China

Server maker Supermicro, based in Fremont, California, is reportedly moving production out of China over customer concerns that the Chinese government had secretly inserted chips for spying into its motherboards.The claims were made by Bloomberg late last year in a story that cited more than 100 sources in government and private industry, including Apple and Amazon Web Services (AWS). However, Apple CEO Tim Cook and AWS CEO Andy Jassy denied the claims and called for Bloomberg to retract the article. And a few months later, the third-party investigations firm Nardello & Co examined the claims and cleared Supermicro of any surreptitious activity.To read this article in full, please click here

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

IT And The Exception Mentality

If you work in IT, you probably have a lot in common with other IT people. You work long hours. You have the attitude that every problem can be fixed. You understand technology well enough to know how processes and systems work. It’s fairly common in our line of work because the best IT people tend to think logically and want to solve issues. But there’s something else that I see a lot in IT people. We tend to focus on the exceptions to the rules.

Odd Thing Out

A perfectly good example of this is automation. We’ve slowly been building toward a future when software and scripting does the menial work of network administration and engineering. We’ve invested dollars and hours into making interfaces into systems that allow us to repeat tasks over and over again without intervention. We see it in other areas, like paperwork processing and auto manufacturing. There are those in IT, especially in networking, that resist that change.

If you pin them down on it, sometimes the answers are cut and dried. Loss of job, immaturity of software, and even unfamiliarity with programming are common replies. However, I’ve also heard a more common response growing Continue reading

Feedback: Data Center Interconnects

Got this feedback from a networking engineer watching the Data Center Interconnects webinar:

This webinar is an excellent overview regarding current DCI design challenges. I would highly recommend to watch it for anyone working in the networking and datacenter space. Sober networkers should watch it thoughtfully at least two times. L2 DCI fans should watch it once in a month, until reaching a solid grasp.

If only life would be as easy as that ;) Most people prefer to be blissfully ignorant of the infrastructure supporting their business, while at the same time pretending they know an awful lot about other people's jobs (see also: Dunning-Kruger effect)
