Hello, this is Lee Do-won. First of all, I would like to apologize as the instructor who prepared the lecture for the fact that you are not satisfied with the lecture. This lecture was prepared as a concept that covers the basics of MSA, understanding of Cloud Native, and an introduction to the basic Inner/Outer Architecture. Since it has been almost two years since the lecture began, we are preparing to update it to a new version starting this spring. If there is any part of the content you mentioned that you would like to improve or if you think there is a part that is lacking, please give me your opinion. I think it will be helpful in updating the lecture. Thank you for your opinion.
