Hello my friend,
after short pause caused by the launch of the Network Automation Training we continue our video blog series. We’ve written a lot about open networking so far and today we talk about it.
In this episode, together with Avi Alkobi from Mellanox we explore the Open Networking world from the Data Centres perspective. On a side note, we discuss the new paradigm for networking: open-source vs. traditional vendor lock-in.
Don’t forget to subscribe for the channel, put likes and repost the video if you like that!

Where is the networking industry with Intent-Based Networking (IBN)? On today's Heavy Networking we talk about efforts to come to some agreement on just what constitutes IBN, dive into graph databases, and examine proposed IETF definitions of the technology. Our guests are Jeff Tantsura, head of networking strategy at Apstra and IETF chair; and Phil Gervasi, a solutions architect.

In November 2019 I wrote an article on using kustomize with Cluster API (CAPI) manifests. The idea was to use kustomize to simplify the management of CAPI manifests for clusters that are generally similar but have minor differences (like the AWS region in which they are running, or the number of Machines in a MachineDeployment). In this post, I’d like to show a slightly different way of using kustomize with Cluster API that involves configuring the kustomize transformers.
If you aren’t familiar with kustomize, I’d recommend having a look at the kustomize web site and/or reading my introductory post. A transformer in kustomize is the part that is responsible for modifying a resource, or gathering information about a resource over the course of a kustomize build process. This page has some useful terminology definitions.
Looking back at the earlier article on using kustomize with CAPI, you can see that—due to the links/references between objects—modifying the name of the AWSCluster object also means modifying the reference to the AWSCluster object from the Cluster object. The same goes for the KubeadmConfigTemplate and AWSMachineTemplate objects referenced from a MachineDeployment. Out of the box, the namePrefix transformer will change the names of these Continue reading

The last few weeks have seen unprecedented changes in how people live and work around the world. Over time more and more companies have given their employees the right to work from home, restricted business travel and, in some cases, outright sent their entire workforce home. In some countries, quarantines are in place keeping people restricted to their homes.
These changes in daily life are showing up as changes in patterns of Internet use around the world. In this blog post I take a look at changing patterns in northern Italy, South Korea and the Seattle area of Washington state.
To understand how Internet use is changing, it’s first helpful to start with what a normal pattern looks like. Here’s a chart of traffic from our Dallas point of presence in the middle of January 2020.
This is a pretty typical pattern. If you look carefully you can see that Internet use is down a little at the weekend and that Internet usage is diurnal: Internet use drops down during the night and then picks up again in the morning. The peaks occur at around 2100 local time and the troughs in the dead of night at around 0300. Continue reading
