It's just amazing. The lecture content is so good. Thanks to it, I was able to build a general foundation for AWS and network knowledge. I don't really know how to write a review, but I was so impressed after listening to about 50% of the lecture that I came to write a review. The voice is so nice and the explanation is really good. It's just a great lecture. I think it's the best lecture among the Inflearn lectures I've taken.
