Sharing over a decade of architecture experience from Baidu, Alibaba, and Tencent.
This guide explains the concept of Nginx static‑dynamic separation, shows how to configure static resource caching and dynamic request routing with upstream groups, and outlines a phased migration plan to improve performance and scalability of web services.
This article provides a comprehensive technical overview of Seata, the open‑source distributed transaction solution from Alibaba, detailing its core components, architecture, and the complete transaction flow with code examples for implementing global transactions in microservice systems.
This article explains how Spring Cloud provides a comprehensive micro‑service toolkit—including service registration and discovery, centralized configuration, load‑balancing strategies, circuit‑breaker fault tolerance, and distributed tracing—while showing practical YAML snippets and component choices such as Eureka, Nacos, Ribbon, Sentinel, Sleuth, Zipkin, and SkyWalking.
This article provides a comprehensive overview of Alibaba’s open‑source Sentinel, detailing its core components, flow‑control strategies—including threshold, multi‑dimensional, hotspot, and adaptive limiting—along with circuit‑breaking and degradation mechanisms, and includes practical Java code examples for integration with Spring Cloud and Dubbo.
This article explains what microservice configuration is, why centralized management is essential, and compares three popular configuration centers—Spring Cloud Config, Nacos, and Apollo—detailing their advantages, disadvantages, and suitable scenarios for cloud‑native architectures.
This guide presents concrete techniques for improving Kafka consumer and producer performance, scaling clusters, tuning broker settings, and designing asynchronous buffering layers to prevent message accumulation and boost overall throughput.
This article provides a concise overview of four major distributed storage solutions—HDFS, Ceph, FastDFS, and GlusterFS—detailing their architectures, advantages, drawbacks, and ideal use cases to help engineers choose the right system for large‑scale data workloads.
This article explains the Nginx master‑slave architecture, how a virtual IP is shared between a primary and backup server using Keepalived and VRRP, and why this simple failover design provides high availability for web services with minimal resources.
This article explains the core Kafka techniques—sequential disk writes, Linux page cache usage, producer/broker batching with compression, and zero‑copy data transfer via sendfile—that together enable massive concurrency and near‑memory write performance in large‑scale streaming architectures.
This article explains forward and reverse proxy fundamentals, illustrates how Nginx reverse proxy works for large websites, and provides a practical configuration example that shows request routing and load‑balancing to backend servers.
