On December 9th, 2020, I created a new GitHub repository and pushed the first commit of my “I hate creating Vagrantfiles by hand” tool. It could create Vagrantfile and Ansible inventory from a (very rudimentary) network topology and deploy handcrafted device configurations on Cisco IOS and Arista EOS.
Dr. Werner Vogels’ keynote at AWS re:Invent 2024 explores how simplicity can lead to complexity, highlighting innovations in AWS services and the importance of maintaining manageable systems.
Simplicity breeds complexity: AWS services like S3 exemplify the journey from simple beginnings to complex systems.
The Two-Pizza Team: Small, autonomous teams enhance innovation while managing complexity effectively.
Continuous learning: Emphasis on adapting structures and processes to accommodate growth and change.
Global scalability: AWS focuses on building technologies that enable businesses to expand effortlessly across regions.
Importance of observability: Understanding and managing system complexity through effective monitoring and metrics.
Security by design: Embedding security measures from the outset to ensure robust systems.
Community involvement: Encouraging tech professionals to support initiatives that address global challenges.
Managing Complexity: Systems evolve over time, and complexity is inevitable. Organizations must strategically manage this complexity to avoid fragility while ensuring functionality.
Evolvability as a Requirement: Building systems with the ability to evolve in response to user needs is essential. Flexibility in architecture allows for future changes without major disruptions.
Decoupling Systems: Breaking down monolithic systems into smaller, independently functioning components enhances Continue readingHello my friend,
We continue our journey from Python to Go (Golang), or more right to say with Python and Go (Golang) together. Today we are going to talk about a data structure, which is by far the most widely used in Python when it comes to a network and IT infrastructure automation and management. This data structure is called dictionaries in Python, or Map in Go (Golang).
Of course, you can. Our self-paced network automation trainings are the perfect place to start your journey in network and IT infrastructure automation or to upskill yourself further if you are seasoned engineer. There is no such thing as excessive knowledge, therefore we encourage you to join our network automation programs and start your study today:
We offer the following training programs in network automation for you:
During these trainings you will learn the following topics:
Palo Alto firewalls come with a default master key used to encrypt passwords, secrets, and certificates. If your firewall is compromised or someone gains unauthorized access, they can easily decrypt these secrets, posing a significant security risk. In this blog post, let's explore why you should change the master key, important considerations, and how to configure it. Let's get started.
Palo Alto firewalls come with a default master key. Anyone with unauthorized access to the firewall can easily decrypt your secrets or export the configuration to another firewall to retrieve those secrets. For this reason, Palo Alto strongly recommends changing the master key as soon as possible.
Configuring the master key isn’t something you can just set and forget; it requires careful consideration. Here are some important points to keep in mind.
No doubt you’ve seen the news that Intel has parted ways with Pat Gelsinger. There is a lot of info to unpack on that particular story but we did a good job of covering it on the Rundown this week. What I really wanted to talk about was a quote that I brought up in the episode that I heard from my friend Michael Bushong a couple of months ago:
No one cuts their way back into relevance.
It’s been rattling around in my head for a while and I wanted to talk about why he’s absolutely right.
Do you remember the coupon clipping craze of ten years ago? I think it started from some show on TLC about people that were ultra crazy couponers. They would do the math and they could buy like 100 lbs of rice for $2. They would stock up on a year’s worth of toothpaste at a time because you could pay next to nothing for it. However, the trend died out after a year or so. In part, that was because the show wasn’t very exciting after the shock of buying two years of hand soap wore off. The other Continue reading
Internet Exchange Points (IXPs) are one of the key centers of Internet infrastructure. How do IXPs work together to build this critical infrastructure? Through ICP associations, such as the African IXP Association. Ricardo Simba joins Tom Ammon and Russ White to talk about a recent meeting of the African IXP Association.

When I discovered GitHub Codespaces (thanks to a pointer by Roman Dodin), I did the absolute minimum of research to get netlab up and running in a container to enable Codespaces-based labs (BGP, IS-IS) and netlab examples.
However, if you want to know the behind-the-scenes details, you MUST read the Codespaces for Network Engineers and Educators deep dive by Julio Perez.

Here’s (in a nutshell) how PIC Edge is supposed to work:
When the hyperscalers and cloud builders were smaller and the Arm collective had failed to storm the datacenter and AMD was not yet on its path to resurgence, it was Intel that controlled the cadence of new compute engine introductions into the datacenter. …
