We explore the .proto file as a "universal order form" for your microservices kitchen and dissect the mechanics of Unary RPC—the fundamental building block of request-response communication. Using Golang examples, we analyze how these contracts enforce rules across languages and why "Schema-First" design is critical for scalable systems. What You Will Learn: First Principles: Understanding .proto files as the "Restaurant Order Form" vs. the chaos of ambiguous APIs. The Mechanics: How to define service, rpc, and message types in Protocol Buffers. Go Implementation: Writing the client and server code for a getProduct Unary RPC. Senior Reality Checks: Handling Schema Evolution without breaking backward compatibility. Production Strategy: Why every Unary call needs a timeout/deadline and how to design for Idempotency. System Design: The trade-offs between synchronous Unary calls and streaming efficiency. Target Audience: Perfect for Backend Engineers, Go Developers, and anyone preparing for System Design Interviews who wants to move from "making it work" to "making it production-ready." 3.
