I’ve seen successful public (infrastructure) cloud deployments… but also spectacular failures. The difference between the two usually comes down to whether the team deploying into a public cloud environment realizes they’re dealing with an unfamiliar environment and acts accordingly.

Please note that I’m not talking about organizations migrating their email to Office 365. While that counts as public cloud deployment when an industry analyst tries to paint a rosy picture of public cloud acceptance, I’m more interested in organizations using compute, storage, security and networking public cloud infrastructure.

A few days ago we published the content outline for our Networking in Public Clouds online course.

We’ll start with the basics, explore the ways to automate cloud deployments (after all, you wouldn’t want to repeat the past mistakes and configure everything with a GUI, would you?), touch on compute and storage infrastructure, and the focus on the networking aspects of public cloud deployments including:

You probably heard me say “networking engineer encountering a public cloud feels like Alice in Wonderland” - packet forwarding works in a different way in every public cloud, subnets are a mix between routed interfaces and VRFs, you cannot change IP addresses without involving the orchestration system…

We covered the networking aspects of Amazon Web Services and Azure in our cloud webinars, but you might need a bigger picture:

Last week I covered network security groups, application security groups and user-defined routes in the second live session of Azure Networking webinar.

We also had a great guest speaker on the Network Automation course: Damien Garros explained how he used central source-of-truth based on NetBox and Git to set up a network automation stack from the grounds up.

Recordings are already online; you’ll need Standard ipSpace.net Subscription to access the Azure Networking webinar, and Expert ipSpace.net Subscription to access Damien’s presentation. Azure Networking webinar is also part of our new Networking in Public Clouds online course.

I have exciting news I’d love to share with you: we’re launching a new online course focused on networking in public clouds starting in February 2020 (I’ve been mulling over this idea and polishing the concept for almost 18 months, and finally it all came together ;)

With Go To The Cloud becoming the answer to all questions (regardless of what the question is), you can find tons of materials describing various aspects of public clouds, so you might wonder why I decided to enter the fray. The answer is simple: with everyone being focused on developers, there’s not much that an infrastructure engineer could use to help him survive when the developers move on and he’s left to manage whatever they put in place.

Last week we started the Autumn 2019 Building Network Automation Solutions online course with an interesting presentation from Matthias Luft focused on open-source supply chain security

TL&DR: Can I download whatever stuff I found as my first Google hit and use it in my automation solution? ****, NO!

Matthias covered these topics:

Last year when I was creating the first version of VMware NSX Deep Dive content, NSX-V was mainstream and NSX-T was the new kid on the block. A year later NSX-V is mostly sidelined, and all the development efforts are going into NSX-T. Time to adapt the webinar to new reality… taking the usual staged approach:

• The new slide deck covering NSX-V and NSX-T is ready. It includes early information about NSX-T release 2.5; I’ll fill in the details once the documentation becomes public.
• I’ll use the slide deck in day-long workshop in Zurich on September 10th.
• The live webinar sessions (including updated NSX-T 2.5 content) will start on November 14th.

Daniel Teycheney attended the Spring 2019 Building Network Automation Solutions online course and sent me this feedback after completing it (and creating some interesting real-life solutions on the way):

I spent a bit of time the other day reflecting on how much I’ve learn’t from the course in terms of technical skills and the amount I’ve learned has been great. I literally no idea about things like Git, Jinja2, CI testing, reading YAML files and had only briefly seen Ansible before.

I’m not an expert now, but I understand these things and have real practical experience on these subjects which has given me great confidence to push on and keep getting better.

More than a decade ago I decided to start a pet project: a blog describing interesting details of networking technologies. The idea quickly morphed into vendor-neutral webinars - the first one took place in February 2010. A year or two later I had my first guest speaker and as of today we had more than 50 industry experts participating in ipSpace.net webinars and online courses.

In the meantime the ipSpace.net team grew: I had video and audio editors for years, Irena Marčetič took over marketing, logistics, and production in 2018, and we got a team of webinar moderators that will help us with guest speaker webinars (last week we ran the first guest speaker webinar where I didn’t have to be involved - hooray ;)

After a few weeks of venting my frustrations on Twitter I finally completed Microsoft Azure Networking slide deck last week and published the related demos on GitHub.

I will use the slide deck in a day-long workshop in Zurich (Switzerland) on June 12^th and run a series of live webinar sessions in autumn. If you’re a (paid) subscriber you can already download the slides and it would be great if you’d have time to attend the Zurich workshop – it’s infinitely better to discuss interesting challenges face-to-face than to type questions in a virtual classroom.

Ladies and gentlemen, our Autumn 2019 Building Network Automation Solutions online course is now ready for boarding. Please make sure you have your boarding passes ready, board at your convenience, and start enjoying the pre-flight perks like over hundred hours of self-study materials.

Our flight will depart on September 3^rd with subsequent sessions on September 26^th, October 24^th and November 12^th. The guest speakers will focus on security, inventory managements, and describe their production deployments. More in a few days…

The only thing you have to do at this moment is to register (if you want to get the Enthusiast price… otherwise please feel free to wait ;)

And just in case you’re wondering: yes, I was sitting at an airport while writing this blog post ;))

Last Thursday I started another experiment: a series of live webinar sessions focused on business aspects of networking technologies. The first session expanded on the idea of three paths of enterprise IT. It covered the commoditization of IT and networking in particular, vendor landscape, various attempts at segmenting customers, and potential long-term Enterprise IT paths. Recording is already online and currently available with standard subscription.

Although the attendance was lower than usual, attendees thoroughly enjoyed it – one of them sent me this: “the value of ipSpace.net is that you cut through the BS”. Mission accomplished ;)

In April 2019 we’re starting a new cloud security saga with Matthias Luft. The first webinar in this series will focus on the basics, subsequent live sessions spread through the rest of 2019 will cover individual technologies.

Another series we’re starting is Business Aspects of Networking, opening on April 4^th with Three Paths of Enterprise IT.

We’ll also continue the math-in-networking series, this time focused on reliability functions and advanced reliability topics.

TL&DR: We ran two workshops in Zurich last week – a quick peek into using Ansible for network automation and updated Building Private Cloud Infrastructure. You can access workshop materials with any paid ipSpace.net subscription.

Now for the fun part…

A European networking engineer sent me this question:

I'd like to know where other fellow engineers meet up especially in Europe and discuss Enterprise datacenter and regular networking. There are the Cisco Live stuff things to go to but are there any vendor neutral meetups?

Gabi Gerber is organizing networking-focused workshops in Switzerland every quarter (search under SIGS Workshops), and you’re most welcome to join us ;) It’s always a boutique event, but that gives us the ability to chat long into the evening.
