Top Architect focuses on sharing practical architecture knowledge, covering enterprise, system, website, large‑scale distributed, and high‑availability architectures, plus architecture adjustments using internet technologies. We welcome idea‑driven, sharing‑oriented architects to exchange and learn together.
A senior architect recounts a code review where a colleague wrapped a simple two‑payment‑method order system in strategy, factory, and abstract‑factory patterns, then explains why such over‑design hurts maintainability, when to apply complex patterns, and practical guidelines for clean backend architecture.
This guide explains three ways to automatically cancel orders that remain unpaid for 30 minutes in a Spring Boot application, covering scheduled tasks, RabbitMQ delayed queues, and Redis key‑expiration events, with complete code examples and configuration details.
This guide introduces RedisInsight, outlines its key features, provides step‑by‑step Linux installation, environment‑variable configuration, service startup, Kubernetes deployment instructions, and demonstrates basic UI usage for monitoring, CLI interaction, and memory analysis of Redis instances.
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.
This guide introduces RedisInsight—a visual Redis GUI—covers its key features, provides step‑by‑step instructions for Linux and Kubernetes installation, explains environment variable configuration, shows how to start the service, and demonstrates basic usage for monitoring and managing Redis instances.
This article walks through the step‑by‑step evolution of a large‑scale e‑commerce backend—from a single‑server setup to microservices, containerization, and cloud platforms—highlighting the technical challenges, key technologies, and design principles that enable millions of concurrent users.
This guide introduces NginxPulse, a lightweight Nginx log analysis panel, explains its key features, shows how to run it with Docker or Docker‑Compose, configure multiple sites, customize log formats, pull remote logs, and troubleshoot common issues, all with concrete commands and examples.
This article explains how to replace repetitive try‑catch blocks in Java Spring applications with a unified exception handling strategy that leverages @ControllerAdvice, custom enums, and assertion utilities, providing clean, maintainable code, internationalized error messages, and consistent response structures for both business and system errors.
