This was really beneficial content.. I'm so excited for other lectures and learned so much. To be specific: 1. I was able to understand why there are implementation limitations with HTTP in MSA. 2. I learned about RPC design that can handle various requirements from basic to advanced levels. 3. I became aware of the considerations needed when using RPC. 4. I was able to learn about content that's not easily known, such as connection optimization and connection reuse at the protocol level. Thank you so much for such a great lecture.
