Istio Now Released!

I got there in the end – Istio is now available at and

Udemy have started a new policy of restricting coupon codes, so the above link will give a “Best Price Match” until 9 November 2019, after that the link will work, but you’ll be subject to Udemy’s strange and complex pricing algorithm – it should still be a reasonable price though.

The aim with this course was to make Istio understandable. It’s not that hard to use really, just for some reason the docs and everything I’ve ever read about Istio seem to be riddled with unnecessary complexities and jargon. On the other hand, I think the course still goes pretty deep – we’re not shy to delve into the underlying Envoy proxies and we meet plenty of Istio gotchas along the way.

I hope this will help demystify Istio and Service Meshes in general. Istio DOES add complexity to a project, so it isn’t for every project. But the payoffs are huge, and I hope I demonstrate this.

A few topics got left behind in the rush to release – but I’ll be adding videos as free updates over time, with the first update being later in November. The main topics that missed the cut were: Mirroring (not complex but I’ve got a cracking demo); RBAC authorization (I don’t think most projects need this, although I may be wrong – but it’s still going to be good to have it in the course); External Services (no special reason why this was missing, but it’s very useful and needs to be added).

Hope to see you there!

    1. Brilliant, thanks Anuj. It bothers me that I’ve still got 3 missing topics but life has got in the way. Still it make a good upgrade later in the year. There’s also some big news on Istio architecture coming up (which I’m not happy about – breaking changes potentially in version 1.5), but I’ll make sure the course is updated to reflect this. Full blog post about this coming soon…

  1. Hi Richard,

    I can’t express how much I appreciate your courses and your intuitive and easy way to express the idea given the complexity of the subject.
    You really helped/helping me a lot.

    I was wondering if you can develop a content for the fleetman with Kafka? That would be awesome!

    Thank you and keep doing great content like such!

    1. Ah thanks Mohamed for those kind words!

      That’s definitely something to consider. My next major course (aim for November) will be a full exploration on Microservices, and there’s going to be a lot of tech in there – I don’t know yet if there will be a need for Kafka in there, but I suspect there might be.

      Failing that, a course in the future would be good.

      All the best!

  2. Hi Richard,

    Your Istio course is really awesome. Perhaps the top 1 among the courses I have attended in Udemy. I’m going to to take your K8s course also!


    1. Ah you’re very kind! I hope the Kubernetes course goes well, I think K8S is actually a better course as the subject is easier to get a grip on. I hope that proves true for you though! Good luck with it!

  3. Hi Richard, I enjoyed learning Kubernetes, Helm, and Istio thanks to your course.

    Do you have any plans to create a Knative course in the future? I am really looking forward to your other CNCF project course.

    1. Hi, thanks for those kind words, glad the courses were useful!
      Knative is definitely something for me to consider, but I’ve slowed down a LOT in the last 3 years. Istio was the last thing I did really (Helm not so long ago but that was really an addition to K8s). I’ve promised to do a GitOps course, but that’s been weeks at the planning stage and still not really started yet. Argh so much to do! I’ll definitely consider knative in the future though – I did start a serverless course last year but then realised there were so many good courses already out there – it’s so competetive now!
      All the best from the UK!

  4. Hi Richard,
    I am really glad I found you on Udemy. The Kubernetes course was absolutely awesome and I wish I could give more than 5 stars for it. I really hope you create another course soon – about anything really, I’m sure it will be fantastic.
    Take care,

    1. Hey sorry for the long delay in replying- WordPress seems to have messed up with comments. Your comment is really kind – I am just about to return to training after a long break, so I’ll be releasing a new course or two this year – I’ll take a long time though. Hope your Kubernetes work is going well! All the best in the meantime!
