This article explains how Spring Cloud Ribbon provides client‑side load balancing, outlines its classification, core mechanisms, common algorithms, and shows step‑by‑step code to replace the default balancing rule in a Spring Boot microservice.
Bilibili performed client-side DCDN disaster-recovery drills using a self-built HTTPDNS to simulate DNS, CDN, and SSL faults; automated scripts across Android, iOS, and Web injected errors, measured rendering latency, validated immediate downgrade to commercial services, refined fallback strategies, and demonstrated near-zero user impact during a real network incident.
This article explains how to implement invisible token refresh for authentication servers using Spring Boot gateway filters, JWT handling, Axios interceptors, and a client‑side timer, compares client‑ and server‑side approaches, and provides complete code examples and practical recommendations.
This guide explains the benefits of caching, defines key DNS concepts, and provides language‑specific investigations and code samples to help developers implement client‑side DNS caching, reduce lookup latency, and improve overall network performance.
This article explains the fundamentals of Vue server‑side rendering, why hydration is needed, the scenarios where it should be used, the typical reasons hydration can fail, and practical steps to diagnose and resolve those failures for more stable frontend applications.
This article explains why client‑side circuit breaking is essential, describes common state‑machine and Google SRE breaker strategies, provides practical pseudocode, and discusses mitigation methods such as Gutter mode, jittered exponential backoff, and graceful degradation to protect system stability.
This article explains Meituan's Phoenix solution that moves CDN disaster recovery to the client side, detailing its goals, architecture, dynamic calculation service, monitoring platform, implementation for web and native apps, and the measurable improvements in availability and operational efficiency.
Meituan’s Phoenix solution equips web and native clients with an automatic CDN failover SDK, dynamic domain selection, and fine‑grained monitoring, dramatically improving resource loading success rates, reducing SRE workload, and ensuring high availability across millions of daily users.
Phoenix is Meituan’s client‑side CDN disaster‑recovery system that uses a Webpack‑based SDK, dynamic calculation service, and monitoring platform to automatically detect load failures, switch domains, isolate problems, and continuously hot‑standby resources, boosting resource success rates from 99.7 % to 99.9 % across hundreds of projects.
This article explains the fundamentals, architecture, strategies, core components, request interception, initialization, synchronization, heartbeat mechanisms, and common configurations of Ribbon, the client‑side load balancer used in Spring Cloud microservice ecosystems.
Taobao redesigned its mobile client’s diagnostics and logging architecture—introducing scenario‑based monitoring, standardized log protocols, snapshot collection, and change‑tracking SDKs—to meet a 5‑minute response, 15‑minute identification, and 60‑minute recovery goal, dramatically improving issue detection, analysis, and resolution efficiency.
This article offers practical engineering guidance on when and how to refactor client‑side code, emphasizing planning, incremental changes, systematic approaches, tooling, and team coordination to improve code quality while minimizing risk and maintaining system stability.
The paper presents a client‑side speech recognizer that uses a compact TensorFlow Lite Inception‑v3 CNN model combined with an optimized MFCC feature pipeline and ARM‑NEON‑accelerated, multi‑threaded processing, achieving low‑latency, high‑accuracy voice recognition on mobile and embedded devices.
