This article explains how to design a high‑concurrency ticket‑snatching service that can handle millions of requests by combining multi‑layer load balancing, weighted Nginx round‑robin, in‑memory stock with Redis‑backed global inventory, and Go’s native concurrency, complete with code samples and performance results.
AI can quickly generate functional code, but turning that 80‑point prototype into a reliable, secure, production‑ready product requires human engineers to perform rigorous validation, refactoring, and polishing—roles the author dubs ‘post‑processing engineers’—who bridge AI’s speed with real‑world robustness and profitability.
The article explains why passing tokens between microservices is a poor design, illustrates the problems with mixed internal‑external APIs, and presents three practical alternatives—explicit parameter passing, centralized authentication via an API gateway with Spring Cloud Gateway and Feign, and a shared auth module with K8s integration—detailing their pros, cons, and implementation steps.
