The training is a great introduction to the concepts of how Angular 5 is working. I enjoyed the mix of theory and practical programming in this course. The trainers are top notch and clearly explains the important concepts. I highly recommend this one.

The Kubernetes course is very hands-on. It switches between short educational sections where you learn the theory and then exercises to practice what you learned. The whole setup is web-based, so no installation is required and no time is lost setting up an environment. It's command-line based and vendor-independent, so it gives you everything to get started with Kubernetes on your own project, no matter what environment you end up using.

I liked the course. The first day of the course started with the basics. All participants were picked up at their level. More time was invested in understanding the issues where there were gaps. Felix Jonas went into detail about the individual participants. The course was very enjoyable. I am looking forward to the CKAD preparation course. Many Thanks.

This course helped me a lot to get a professional understanding of containers and to get a first dive into Kubernetes. -- Tobias Schmocker, Data Engineer, Axpo Grid AG

Martin - Software Engineer I was already using Cypress E2E Testing, but the course was still very helpful to fill the knowledge gaps and get a deeper understanding of how Cypress Tests work under the hood. It also helped us to improve our CI/CD pipelines and made our tests more stable. I really enjoyed the two day training session! Thank you Jonas and keep up the good work!

Really good introduction to Angular. I think I will be able to develop application in an efficient way now.

Der Kurs „Container & Kubernetes DevOps“ bei letsboot.ch hat mir einen hervorragenden Einblick in die moderne Infrastruktur-Automatisierung ermöglicht.
