After the fantastic Docker 101 webinar by Matt Oswalt a few people approached me saying “that was great, but we’d need something more on Docker networking”, and during one of my frequent chats with Dinesh Dutt he mentioned that he already had the slides covering that topic.

Problem solved… and Dinesh decided to do it as a free webinar (thank you!), so all you have to do is register. Hurry up, there are only 1000 places left ;)

Failure to use DNS, IP addresses embedded in the code, ignoring the physical realities (like bandwidth and latency)… the list of mistakes that eventually get dumped into networking engineer’s lap is depressing.

It’s easy to reach the conclusion that the people making those mistakes must be stupid or lazy… but in reality most of them never realized they were causing someone else problems because nobody told them so.

Occasionally I get feedback that makes me say “it’s worth doing the webinars ;)”. Here’s one I got after the layer-2 session of Leaf-and-Spine Fabric Designs webinar:

I work at a higher level of the stack, so it was a real eye opener especially with so much opinionated "myths" on the web that haven't been critically challenged such as [the usefulness of] STP.

There’s more feedback on this web page where you can also buy the webinar recording (or register for the next session of the webinar once they are scheduled).

The featured webinar in May 2016 is the Overlay Virtual Networking webinar and in the featured videos (the ones marked with a star) you'll find introduction to overlay virtual networking and deep dive into flooding and MAC address learning in layer-2 overlay virtual networks.

I’m presenting at two Data Center Interest Group Switzerland events organized by Gabi Gerber in Zurich in early June:

• In the morning of June 7th we’ll talk about software-defined security, data center automation and open networking;
• In the afternoon of the same day (so you can easily attend both events) we’ll talk about VMware NSX microsegmentation and real-life implementations.

I hope to see you in Zurich in a bit more than a month!

When I started thinking about my first online course, I decided to create something special – it should be way more than me talking about cool new technologies and designs – and the guest speakers are a crucial part of that experience.

The first guest speaker is one of the gurus of network design and complexity, wrote numerous books on the topic, and recently worked on a hardware-independent network operating system.

Russ White wrote a great response to my “Do You Really Want to Write that Book?” blog post and I couldn’t agree more with what he wrote. Unfortunately, he seems to be a bit over-idealistic when analyzing why the market for high-end content is so small.

You know I usually have a cynical explanation handy, so here it is: too many people calling themselves engineers for no particular reason simply don’t care. It’s way easier to Google-and-paste your way around than to invest time in understanding the fundamentals.

After I told you that I’m not going to Interop, I got numerous emails along the lines of “but I was really looking forward to attending your workshop” so I started looking for a solution that would combine the best of online and classroom worlds.

Here’s my first attempt: an interactive online course combining topics from two of my Interop workshops. I’m still working on the detailed agenda and plan to have it ready around May 1st. In the meantime, I’d really appreciate your feedback – leave a comment or send me an email.

One of my readers sent me this question:

Considering I know nothing about anything SDN-related (and considering it seems "SDN" means something different depending to whom you are asking), where should someone with no knowledge of SDN start?

The obvious answer: sdn.ipSpace.net. On a more serious note:

I had a sweet problem with ipSpace.net webinars for quite a while: there are way more ideas than available time. However, a few days ago I stumbled upon a great tip on Trello blog and immediately decided to use it.

Result: list of future ipSpace.net webinars as a Trello board.
