Learn Istio service mesh is a course I've been working on for the past year. Originally, it started as an e-book and recently I added more than 2 hours of video content to accompany the book.
I've always liked courses that teach concepts through practical examples. The theory is definitely something one needs to understand, but I feel learning from practical examples and scenarios is what helped me to really grasp the concepts and that's how I built this course.
I'd love to answer any questions you might have about the course and don't hesitate to contact me at peter[at]learnistio.com.
