This guide explains how to quickly deploy a JD Chain blockchain environment by downloading the peer and gateway packages, configuring ports, initializing nodes, creating keys and ledgers, and launching management tools, providing step‑by‑step commands and screenshots for a complete setup.
This article explains how Zhihu designed a scalable long‑connection gateway that decouples business logic via a publish‑subscribe model, implements ACL‑based authorization, ensures message reliability with acknowledgments and sliding windows, and leverages OpenResty, Redis, and Kafka for load‑balanced, fault‑tolerant backend services.
UCloud’s external gateway redesign leverages Linux kernel 5.0 features—lightweight tunneling, VRF, and flow offload—to replace OVS/GRE tunnels, addressing IP tunnel complexity, tenant isolation overhead, and netns performance penalties, while contributing patches back to the open‑source community.
This article reviews the Spring Cloud Greenwich.RELEASE launch, detailing Maven coordinates for Java 11 compatibility, new features such as upgraded Netflix components, CredHub configuration for Spring Cloud Config, OAuth2 integration in Spring Cloud Gateway, recent Feign enhancements, common pitfalls, and practical migration tips for developers.
This article explains how OpenResty, built on Nginx and Lua, powers JD Logistics' high‑throughput, extensible gateway by leveraging non‑blocking I/O, plugin architecture, multi‑level caching, dynamic load balancing, and custom JSON handling to achieve stable, scalable performance.
The article explains why microservices require a gateway for unified requests, monitoring, rate limiting, authentication, and troubleshooting, then introduces Soul as a high‑performance reactive gateway, detailing its features, key highlights, and the scenarios where it is most suitable.
This article outlines the overall architecture of a generic open platform, detailing its web server, API gateway, portal, management services, service registry, security components, OAuth, service composition, and best‑practice security measures for building a robust backend system.
This article describes how JD's open gateway handles billions of requests during major sales events by employing a multi‑layer architecture, Nginx + Lua unified access, NIO asynchronous processing, service isolation, dynamic routing, degradation, rate‑limiting, circuit‑breaking, fast‑fail mechanisms, and comprehensive monitoring to ensure high performance and reliability.
This article explores the core components of a microservice foundation framework—including gateways, DevOps, Docker, security, load balancing, and service discovery—examines centralized vs. in‑process load‑balancing strategies, and reviews Netflix’s open‑source stack (Eureka, Zuul, Hystrix, etc.) as a reference implementation.
The talk presented at the Global Architect Summit detailed JD Daojia's backend architecture evolution, covering physical deployment, microservice adoption, gateway design, LBS caching, order system structure, idempotency, data consistency, high‑availability strategies, gray releases, rate limiting, and stress testing, illustrating practical engineering challenges and solutions.
This article chronicles Meituan's payment channel gateway evolution—detailing early usable stages, subsequent availability improvements, and the implementation of a flexible, fault‑tolerant architecture that achieved 99.99% API uptime and record‑high transaction throughput.
This article details how Ctrip transformed its travel app by consolidating product versions, redesigning the wireless backend with a Zuul‑based gateway, decoupling the app engineering into independent modules, implementing extensive performance monitoring, and adopting native plugin and hot‑fix solutions to boost stability and user experience.
This article explains how to design a gray‑release solution for HTTP read interfaces by using either Nginx with embedded Lua scripts or a version‑aware gateway layer, detailing rule design, configuration handling, and the trade‑offs of each approach.
The article describes Ctrip Tech's Gateway system, detailing its origin as a monolithic wireless service, the need for gradual decoupling, the implementation process for HTTP and TCP traffic, and the resulting features such as routing, isolation, rate limiting, circuit breaking, anti‑scraping, and monitoring.
