This lecture provides a shallow but broad knowledge of server development. I think it is good for beginners because you can experience the basics of one cycle of server development, from the definition of the server to basic API writing, DB connection, and distribution. I am confident that I can study efficiently if I listen to this lecture first and then study more deeply, so I am paying a lump sum even though it is expensive. The explanations are good and the content organization is good for seeing the big picture, so it seems suitable as the first lecture for those who want to study server development from a top-down method rather than a bottom-up method. Since the lecture content and delivery are good, if you become familiar with Java development, I think you should also consider the Coping lecture.
