Hello. First of all, I would like to thank the instructor who explained the AWS EKS cluster technology in detail and disclosed it. I always felt lacking because I was always pressed for time while doing infrastructure development in the field, so I couldn't study in depth. However, after looking at the lecture table of contents, I decided that I had to listen to it, so I purchased it, and as expected, it was a great help in understanding the functions provided by AWS EKS cluster (k8s) again because it explained it in detail in a calm voice from the beginning. In particular, the demonstration of AWS VPC-CNI operation sequentially up to the tcp dump level helped me understand the EKS cluster network properly. I also liked that the karpenter (cluster autoscaler) part was explained in a separate session.
