Daniel Dib asked a sad question on LinkedIn:

Where did all the great documentation go?

In more detail:

There was a time when documentation answered almost all questions:

• What is the thing?
• What does the thing do?
• Why would you use the thing?
• How do you configure the thing?

I’ve seen the same thing happening in training, and here’s my cynical TL&DR answer: because the managers of the documentation/training departments don’t understand the true value of what they’re producing and thus cannot justify a decent budget to make it happen.

I migrated my blog to Hugo two years ago, and never regretted the decision. At the same time I implemented version control with Git, and started using GitHub (and GitLab for a convoluted set of reasons) to host the blog repository.

After hesitating for way too long, I decided to go one step further and made the blog repository public. The next time a blatant error of mine annoys you fork it, fix my blunder(s), and submit a pull request (or write a comment and I’ll fix stuff like I did in the past).

Andy Lemin sent me such a wonderful review of ipSpace.net materials that I simply couldn’t resist publishing it ;)

ipSpace.net is probably my favorite networking resource out there. After spending years with other training content sites which are geared around certifications, ipspace.net provides a totally unique source of vendor neutral opinions, information, and anecdotes – the kind of information that is just not available anywhere else. And to top it off, is presented by a wonderful speaker who is passionate, smart and really knows his stuff!

The difference between an engineer who just has certs versus an engineer who has a rounded and wide view of the whole industry is massive. An engineer with certs can configure your network, but an engineer with all the knowledge this site provides, is someone who can question why and challenge how we can configure your network in a better way.

It’s hard to believe, but another year has swooshed by, and it’s time to shut down my virtual office and disappear until mid-January. Of course I’ll be around in case of urgent support problems – I will read my email, but won’t reply to 90% of the stuff coming in.

I hope you’ll be able to find a few days to disconnect from the crazy pace of networking world and focus on your loved ones. I would also like to wish you all the best in 2022!

In February 2018, Irena Marčetič joined ipSpace.net to fix the (lack of) marketing. After getting that done, she quickly took over most of sales, support, logistics, content production, guest speaker coordination… If you needed anything from us in the last few years, it was probably Irena answering your requests and helping you out.

She did a fantastic job and transformed ipSpace.net from Ivan and an occasional guest speaker to a finely tuned machine producing several hours of new content every month. She organized our courses, worked with guest speakers, podcast guests and hosts, participated in every guest speaker webinar to take notes for the editing process, managed content editing, watched every single video we created before it was published to make sure the audio was of acceptable quality and all the bloopers were removed… while answering crazy emails like I need you to fill in this Excel spreadsheet with your company data because I cannot copy-paste that information from your web site myself and solving whatever challenges our customers faced.

Unfortunately, Irena decided to go back to pure marketing and is leaving ipSpace.net today. Thanks a million for all the great work – we’ll badly miss you.

It’s time for another this is what we did in the last six months blog post. Instead of writing another wall-of-text, I just updated the one I published in early January. Here are the highlights:

• Completed webinars: Kubernetes Networking Deep Dive, Cisco ACI Deep Dive
• Totally unplanned: AI/ML in Networking
• New content in existing webinars: NSX-T Federation, Leaf-and-Spine routing designs, deep dive into reliability theory, AWS Gateway Load Balancer and Network Firewall, Azure Virtual WAN, multi-vendor data center EVPN deployments, networking part of Introduction to Cloud Computing webinar.
• Updated content: configuration and state management automation tools.
• Work-in-progress: Network Automation Concepts

That’s about it for the first half of 2021. I’ll be back in early September.

One of our subscribers sent me this question:

I am a system administrator working primarily on server/storage virtualization. How would you recommend I take full advantage of the subscription while not being in networking full-time?

Let’s start with the webinars focused on technologies and fundamentals:

• If you’re interested in networking fundamentals, go through the first part of How Networks Really Work — stop when you feel it’s turning into a deep dive.
• As a sysadmin, you probably work within a data center environment. Data Center Infrastructure for Networking Engineers is another fundamentals-focused webinar worth exploring.
• Involved in multi-site DC deployments? Check out the Data Center Interconnects and Designing Active-Active and Disaster Recovery Data Centers.
• On the storage side, there’s Hyper-Converged Infrastructure Deep Dive and The Network Impact of NVMe over Fabrics (NVMe-oF).

When I started developing AWS- and Azure Networking webinars, I wondered whether they would make sense – after all, you can easily find tons of training offerings focused on public cloud services.

However, it looks like most of those materials focus on developers (no wonder – they are the most significant audience), with little thought being given to the needs of network engineers… at least according to the feedback left by one of ipSpace.net subscribers.

As I started Software Gone Wild podcast in June 2014, I wanted to help networking engineers grow beyond the traditional networking technologies. It’s only fitting to conclude this project almost seven years and 116 episodes later with a similar theme Avi Freedman proposed when we started discussing podcast topics in late 2020: how do we make networking attractive to young engineers.

Elisa Jasinska and Roopa Prabhu joined Avi and me, and we had a lively discussion that I hope you’ll find interesting.

A while ago, someone made a remark on my suggestions that networking engineers should focus on getting fluent with cloud networking and automation:

The running thing is, we can all learn this stuff, but not without having an opportunity.

I tend to forcefully disagree with that assertion. What opportunity do you need to test open-source tools or create a free cloud account? My response was thus correspondingly gruff:
