It was a great lecture that taught me about AWS and Docker in general. I always felt frustrated because I didn't know which direction to study for deployment. I felt good because I learned enough background knowledge while watching this lecture. I think I repeatedly deployed and deleted it several times so that I wouldn't forget it. While listening to the lecture, I think it would be good to take notes of the parts that you think you need to study additionally and study them. Thank you for opening the way.
