RPC Processing Techniques for Ensuring Performance in Hundreds of MSA Environments, Taught by Developers from Kakao and Toss

This course covers RPC communication techniques for maximizing performance in large-scale MSA (Microservice Architecture) environments. Going beyond simple gRPC practice, you will learn how to implement stable and efficient service-to-service communication in real-world production environments where hundreds of microservices operate simultaneously. Based on Golang, the course takes a practical, hands-on approach to writing Protocol Buffers (proto) syntax, generating code automatically and implementing services, understanding gRPC’s architecture and advantages over traditional RPC, and applying performance optimization strategies. To ensure that even non-majors and beginners in server development can easily follow along, it explains everything step by step—from the concept of RPC to gRPC’s internal operating principles—helping you develop practical skills that can be applied directly to real-world services.
