This article breaks down four common data permission implementations, comparing role‑menu binding, user‑role‑scope binding, hybrid approaches, and a menu‑dimension‑role instance design, highlighting their trade‑offs and guiding architects toward a precise, scalable solution.
This article details the design, architecture, and evolution of a self‑developed customer instant‑messaging system, covering its user‑centred philosophy, layered backend structure, technology choices such as WebSocket and Spring WebFlux, and how it solved challenges in gateway design, session storage, message ACK, and queue management to achieve high availability, security, and future‑ready scalability.
This article explains how to design a practical feed‑flow system for enterprises, covering core concepts, feed types, initialization, push‑pull versus pure push strategies, and provides key Java code snippets that illustrate Redis‑based storage and update mechanisms.
This article details the design and implementation of a high‑performance, highly available membership platform serving billions of users, covering dual‑center Elasticsearch clusters, traffic‑isolated three‑cluster ES architecture, Redis caching strategies, MySQL dual‑center partitioning, seamless migration, and fine‑grained flow‑control and degradation mechanisms.
This article explains the fundamentals of micro‑services architecture, then shows how its principles extend to the front‑end as micro‑frontends, detailing core concepts such as technical independence, isolated code, naming conventions, native browser communication, resilient design, and the many advantages they bring to modern web development.
The article explores the fundamental concepts of system architecture, illustrating how large‑scale services like Weibo handle massive traffic through layered design, abstraction, caching, service decomposition, monitoring, and operational practices to achieve scalability, reliability, and performance.
From the manual offline 1.0 system to the real‑time, AI‑driven Hermes platform, Xianyu Push evolved through 1.1’s richer feed layout, personalized timing, and IFTTT‑style triggers, ultimately delivering higher click‑through rates, broader scene coverage, and stronger daily active user activation.
This article outlines a comprehensive, multi‑layer web architecture covering front‑end optimization, application‑level frameworks, service‑oriented components, storage solutions, backend analytics, monitoring, security measures, and data‑center design for building highly scalable and reliable websites.
To build a scalable CRM, the article proposes a four‑step framework—defining goals, applying a full‑process digitalization methodology, designing a flexible, component‑based architecture that emphasizes configuration and light databases, and assembling an execution‑focused team—while detailing revenue‑maximizing levers, digitalization layers, and a closed‑loop feedback system.
This article traces the evolution of Weibo’s recommendation architecture across three major phases—independent 1.0, layered 2.0, and platform‑centric 3.0—detailing the environmental drivers, technical components, advantages, shortcomings, and key outcomes of each stage.
