Sharing over a decade of architecture experience from Baidu, Alibaba, and Tencent.
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.
This guide explains Nginx's core configuration concepts—including directives, contexts, server and location blocks—provides practical examples for setting up virtual hosts, reverse proxies, load balancing, SSL/TLS, gzip compression, and custom error pages, and offers performance‑optimisation tips for production environments.
This guide explains how Nginx can separate static resources from dynamic content, outlines the underlying principle, and provides a complete configuration example that improves response time and concurrency by serving files directly and proxying application requests to backend servers.
The article explains how Kafka attains high‑throughput performance by using sequential disk writes, leveraging the OS page cache, employing producer and consumer batching with configurable parameters, and utilizing zero‑copy sendfile to minimize CPU and memory overhead, enabling stable million‑message per second rates.
This guide explains ten practical Nginx optimizations—including event‑driven handling, worker process tuning, gzip compression, static and dynamic caching, DNS resolver settings, TCP_NODELAY, logging adjustments, request rate limiting, and HTTP/2 activation—to dramatically improve server throughput and latency.
This article explains Nginx's event‑driven architecture, asynchronous non‑blocking I/O, and master‑worker multi‑process model, showing how these techniques eliminate waiting, maximize resource utilization, and enable the server to handle massive concurrent connections efficiently.
This article explains Nginx’s lightweight, high‑concurrency design, detailing its master‑worker process model, asynchronous event‑driven reactor pattern, and key advantages such as stability, hot‑reloading, and efficient I/O handling for modern web applications.
This article explains Nginx's high‑performance architecture, detailing the roles of the Master and Worker processes, their responsibilities, and the step‑by‑step workflow from receiving a client request to generating and sending the HTTP response.
This article explains the fundamentals of distributed transactions, illustrates why they are essential for multi‑service operations such as e‑commerce order processing, and compares four major solutions—two‑phase commit, three‑phase commit, TCC, and message‑queue based eventual consistency—detailing their workflows, advantages, and drawbacks.
