New Video Course: How Networks Really Work

Those who follow my work know I’ve been focused on building live webinars for the last year or two, but I am still creating pre-recorded material for Pearson. The latest is built from several live webinars which I no longer give; I’ve updated the material and turned them into a seven-hour course called How Networks Really Work. Although I begin here with the “four things,” the focus is on a problem/solution view of routed control planes. From the description:

There are many elements to a networking system, including hosts, virtual hosts, routers, virtual routers, routing protocols, discovery protocols, etc. Each protocol and device (whether virtual or physical) is generally studied as an individual “thing.” It is not common to consider all these parts as components of a system that works together to carry traffic through a network. To show how all these components work together to form a complete system, this video course presents a series of walk throughs showing the processing involved in various kinds of network events, and how control planes use those events to build the information needed to carry traffic through a network.

You can find this How Networks Really Work here.

Creative Virtual Team Building Ideas

Handling a remote team is not the easiest task. They have fewer opportunities to socialize and they don’t have a way to get to know new members. Such remoteness in work can lead to feelings of disconnection and isolation.

That is why your business needs virtual team building activities. It will allow the workers to get to know each other and feel more connected. They will drive a sense of belonging and community that everyone needs.

Here are our top choices for creative virtual team building activities.

1. Weekly Trivia Contest

People love trivia. Jeopardy is a big example of how much people love taking part in trivia contests. So, you can create such a contest for your virtual team as well.

You can decide:

  • Categories (Current events, entertainment, science, etc.)
  • Timing (Day the contest will take place)
  • Difficulty (Beginner, intermediate, or advanced)
  • Region (Do you want to include your global teammates or just the ones in your state?)

If you want a platform for automated weekly trivia quizzes for your remote team, then you can opt for Water Cooler Trivia. It is a platform that will automate the entire process to make things seamless. It is one Continue reading

Dynamic URL Rewriting at the edge with Cloudflare

Dynamic URL Rewriting at the edge with Cloudflare
Dynamic URL Rewriting at the edge with Cloudflare

URLs are ugly. They are hard to read, difficult to memorise and often auto-generated for the benefit of the origin server - not the user.

Today we are announcing the immediate availability of Transform Rules for all Cloudflare plans. Transform Rules provide Cloudflare administrators with the ability to create URL rewrite rules. These rules transform HTTP requests as they flow through Cloudflare providing an interpretation layer between the human friendly and the computer friendly.

Ease of understanding

Imagine you are going on a much needed around-the-world trip and want to buy a copy of John Graham-Cumming’s book The Geek Atlas: 128 Places Where Science and Technology Come Alive to use as inspiration. Would the link https://www.travelbooks247.com/dp/0596523203/ make sense to you? Chances are the answer is no. It's hard for humans to understand these complex, contextless URLs.

This is why companies instead provide user friendly alternatives such as: https://www.travelbooks247.com/Geek-Atlas-Places-Science-Technology/dp/0596523203/ and use web servers as the interpreter. This interpretation is known as URL rewriting.

Large ecommerce retailers take HTTP requests to these human-friendly URLs and rewrite them using a simple pattern that strips the content Geek-Atlas-Places-Science-Technology/ before sending the HTTP request to the backend. The human readable hyperlink Continue reading

Claim: You Don’t Have to Be a Networking Expert to Do Kubernetes Network Security

I was listening to an excellent container networking podcast and enjoyed it thoroughly until the guest said something along the lines of:

With Kubernetes networking policy, you no longer have to be a networking expert to do container network security.

That’s not even wrong. You didn’t have to be a networking expert to write traffic filtering rules for ages.

Jonathon Dixon: Why I joined Cloudflare

Jonathon Dixon: Why I joined Cloudflare
Jonathon Dixon: Why I joined Cloudflare

I’m excited to announce that on March 1, I joined Cloudflare as Vice President and GM, Asia Pacific (including Japan and Greater China) to help build and expand Cloudflare’s growing customer and partner base and presence in the region. We currently have over 200 passionate and customer-focused employees in APAC, with offices in Beijing, Singapore, Sydney and Tokyo.

A little about me

Singapore is where I’m based. Melbourne is home with my early years spent in Country Victoria. I love the outdoors, sports, travelling and spending time with family and friends. I am naturally intrigued by interesting people and different perspectives. I have a thirst for learning and understanding why people act and behave the way they do, and believe that understanding more about different cultures makes me a better person/leader. And what better way to do so than by being in the most diverse region in the world — Asia Pacific is home to 60% of the world’s population, with thousands of languages spoken, spanning multiple time zones. With the rise of innovation and technology adoption in the region, growth and expansion opportunities are endless.

My journey to Cloudflare

Throughout my 20-year career, I have been extremely fortunate to Continue reading

Where is the the border between network automation and software development?

In order to automate any network operation, you need to write a script, even if that is a simple one. On the other hand, any script is a program or software. This means that the creating of the scripts for the network automation is a form of the software development. And it is fun. Continue reading
