gRPC Basics

Summary

A high-performance RPC framework using Protocol Buffers for efficient binary serialization — common for internal service-to-service communication where speed matters more than human-readability.

• 1Read a Protocol Buffers (`.proto`) file and identify the defined service and messages.
• 2Compare gRPC's binary format to JSON's readability and size trade-offs.
• 3Understand gRPC is typically used between backend services, not directly from browsers.
