AI is the new SDN, and we’re constantly bombarded with networking vendor announcements promising AI-induced nirvana, from reinventing Clippy to automatic anomaly- and threat identifications.
If you still think these claims are realistic, it’s time you start reading what people involved in AI/ML have to say about hype in their field. I posted a few links in the past, and the Packet Pushers Human Infrastructure magazine delivered another goodie into my Inbox.
You REALLY SHOULD read the original article, here’s the TL&DR summary for differently-attentive:

As a response to my Live vMotion into VMware-on-AWS Cloud blog post Nico Vilbert pointed me to his blog post explaining the details of cross-Atlantic vMotion into AWS.
Today I will not go into yet another rant pointing out all the things that can go wrong, but focus on a minor detail: “no ping was dropped in the process.”
The vMotion is instantaneous and lossless myth has been propagated since the early days of vMotion when sysadmins proudly demonstrated what seemed to be pure magic to amazed audiences… including the now-traditional terminal window running ping and not losing a single packet.

Anne Baretta got pretty far in his automation story: after starting with configuration templates and storing network inventory into a database, he tackled the web UI. What’s next? How about a few auto-generated network diagrams?

A pretty good summary of the topic by Drew Conry-Murray: the market is not going to correct itself, it’s very hard to hold manufacturers or developers accountable for security defects in their products, and nothing much will change until someone dies.
And just in case you wonder how "innovative forwarding-looking disruptive knowledge-focused" companies could produce such ****, I can highly recommend The Stupidity Paradox.

After the “shocking” revelation that a network can never be totally reliable, I addressed another widespread lack of common sense: due to laws of physics, the client-server latency is never zero (and never even close to what a developer gets from the laptop’s loopback interface).

Starting with a short message to anyone interested in our on-site events in Switzerland: on March 10th we’re running our first 2020 workshop, focusing on Docker and containers.
I totally reworked the material, adding tons of new Docker networking examples (including deep dive into iptables) and a few fun things like building an Ansible container, or starting the whole NetBox stack with a single command. Even if you don’t plan to deploy containers in your production network, you might drop by just for that part.
And now for the upcoming webinars:

Every now and then someone tries to justify the “wisdom” of migrating VMs from on-premises data center into a public cloud (without renumbering them) with the idea of “scaling out into the public cloud” aka “cloud bursting”. My usual response: this is another vendor marketing myth that works only in PowerPoint.
To be honest, that statement is too harsh. You can easily scale your application into a public cloud assuming that:

While running the Using VXLAN And EVPN To Build Active-Active Data Centers workshop in early December 2019 I got the usual set of questions about using BGP as the underlay routing protocol in EVPN fabrics, and the various convoluted designs like IBGP-over-EBGP or EBGP-between-loopbacks over directly-connected-EBGP that some vendors love so much.
I got a question along the same lines from one of the readers of my latest EPVN rant who described how convoluted it is to implement the design he’d like to use with the gear he has (I won’t name any vendor because hazardous chemical substances get mentioned when I do).

Imagine you followed the steps taken by Anne Baretta and stored network inventory into a database. What could you do with that information (apart from creating reports)? How about adding a web UI to help less-skilled network operators perform automated tasks?

After introducing FRRouting architecture, Donald Sharp dived deep into configuration and performance optimizations, including asynchronous data plane, next hop groups, and commit-and-rollback.
