Interview: What New Technologies Should You Aim to Master?
In the last part of my chat with David Bombal we discussed interesting technologies networking engineers could focus on if they want to grow beyond pure packet switching (and voice calls, if you happen to believe VoIP is not just an application). We mentioned public clouds, automation, Linux networking, tools like Git, and for whatever reason concluded with some of my biggest blunders.

IPv6 Fragmentation Loss
In this report I would like to revisit this measurement of packet drop for IPv6 Fragmented packets and see if the picture has changed over the intervening four years since we last measured this behaviour.Installing AWX 19 on MicroK8s in AWS
AWX is now deployed on Kubernetes (since AWX release 18), which is great – the only thing is, what do you do if this is the only application you need Kubernetes for? It is a bit of a hassle setting up the K8s master and worker nodes just for a single application.
The documentation suggests you use Minikube for this, but that seems to be designed for local / testing use only. There’s no middle ground between these two options, so I decided to work it out on MicroK8s.
MicroK8s is Canonical’s minimal production Kubernetes environment. It installs on one host, but can be set up for high availability and even run on a Raspberry Pi!
Here are the instructions if you want to do the same.
Install an Ubuntu 20 host on a t2.medium or higher instance in AWS.
Give it 20Gb of general purpose SSD disk.
Create a security group that permits TCP/443 through from your location – only TCP/22 is permitted by default.
Install Microk8s on a new Ubuntu host in AWS:
ubuntu@ip-172-31-0-208:~$ sudo snap install microk8s --classic microk8s (1.20/stable) v1.20.5 from Canonical✓ installed ubuntu@ip-172-31-0-208:~$
Add the ‘ubuntu’ user you are logged in Continue reading

What’s the Controversy Over Bitcoin?
Bitcoin – something we have all heard of but never fully understand what the hype is all about. Apart from the hype, there are always news headlines regarding the scandals related to bitcoin. All of this talk in town only leads us to one question: what’s the controversy over Bitcoin?
For starters, you need to know what Bitcoin is. According to the company, they are the pioneers of a peer-to-peer payment network that involves no intermediary. Here , the first controversy begins: governments are highly against cryptocurrencies like Bitcoin simply due to the lack of a middleman during the buying and selling of money or commodities.
Governments and Money: What’s the Relationship?
Governments are the ones who issue currencies to their people. While currencies are merely numbers printed on pieces of paper or metal, the government claims that they have value, and the general population believes them. These notes and coins are then used to make transactions of all kind, and the money flows around through the entire economy.
However, conventional currencies do not have any actual value since they cannot be given back to the government in exchange for commodities. If you want to purchase even something as simple Continue reading
Why IT Leaders Should Make Cloud Training a Top Priority
As IT operations continue drifting into the cloud, it's important to ensure that organization personnel keep pace with the latest skills and practices.Microsoft Azure: Remember Exchange Server?
Recently I joked there’s significant difference between AWS and Azure launching features:
- AWS launches a production-ready feature that you can consume the next day.
- Azure launches a preview that might work in 6 months.
Those with long enough memories shouldn’t be surprised. It’s not the first time Microsoft is using the same tactics.

The Hedge 80: Ian Goetz and 5G
Although there are varying opinions 5G—is it real? Is it really going to have extremely low latency? Does the disaggregation of software and hardware really matter? Is it really going to provide a lot more bandwidth? Are existing backhaul networks going to be able to handle the additional load? For network engineers in particular, the world of 5G is a foreign country with its own language, expectations, and ways of doing things.
On this episode of the Hedge, Ian Goetz joins Tom Ammon and Russ White to provide a basic overview of 5G, and inject some reality into the discussion.
How to Implement Network Segmentation with Zero Changes to Your Network
Across industries, network segmentation is quickly becoming a critical capability for enterprises of all sizes. Why? First, network segmentation prevents the lateral spread of threats inside the network. Second, it separates dev, test, and production environments. And lastly, it meets increasingly complex compliance requirements while enabling a Zero Trust security strategy.
However, historically network segmentation has been fraught with operational challenges and limited by platform capabilities, leading to the perception that setting up and configuring segmentation policies requires massive changes to the physical network as well as a complex, bloated, and costly deployment of physical firewall appliances.
Not anymore. VMware takes a distributed, software-based approach to segmentation, eliminating the need to redesign your network in order to deploy security. Instead, segmentation policies are applied at the workload level through NSX Firewall, which is deployed on top of your existing VSphere 7 environments. This allows you to easily create zones in the data center where you can separate traffic by application or environment — providing the quickest and easiest way to achieve your data center segmentation Continue reading
