I'm a developer who worked at Kakao and created this course together with Hong!! I think there are many people who can't properly explain the connection between RPC communication and MSA architecture, and don't understand the importance of their compatibility. If you can say "I've implemented MSA down to the core level," I believe you must be able to utilize RPC to optimize network-level resources and explain what aspects you improved in this process. I've prepared this course based on that topic, and I hope you'll find it very helpful after watching the course. Thank you!
