Sharing over a decade of architecture experience from Baidu, Alibaba, and Tencent.
The article explains TPS (Transactions Per Second), shows how to calculate it with a concrete example, and outlines industry‑based concurrency tiers—from less than 100 TPS for ordinary systems up to 50,000+ TPS for billion‑level traffic platforms—helping readers understand what counts as high concurrency.
The article explains how Nginx’s two‑layer caching—browser and proxy—works, why it can reduce backend load and latency, often delivering more than tenfold performance gains for read‑heavy static content, and provides detailed configuration directives such as proxy_cache_path, proxy_cache, proxy_cache_valid, and best‑practice settings to ensure cache validity and avoid cache stampede.
This article provides a detailed walkthrough of the 15 most commonly used Redis commands—including key, hash, list, set, sorted‑set, and monitoring operations—showing syntax, return values, typical use cases, performance characteristics, and cautions for production environments.
This article provides a concise, step‑by‑step guide to the fifteen most frequently used Nginx commands, showing how to check versions, start, stop, reload, test configurations, view logs, monitor connections and ports, and troubleshoot common errors on Linux systems.
This article explains why Nginx’s “master‑slave” term refers to a high‑availability setup, details the four‑layer architecture, shows a complete configuration example, and walks through the failover process using VIP and Keepalived.
This article explains how Nginx functions as a reverse proxy, detailing its role as a unified entry point that hides backend servers, improves concurrency, and can be deployed in single‑node, load‑balanced, or multi‑layer architectures with concrete configuration examples and design considerations.
The article explains Nginx’s core load‑balancing mechanisms, detailing four primary scheduling algorithms—Round Robin, Weighted Round Robin, IP Hash, and Least Connections—along with their advantages, drawbacks, and suitable scenarios, illustrated with diagrams and example configurations.
The article explains that MySQL redo log operates at the InnoDB engine layer to ensure transaction durability and crash recovery, while binlog works at the server layer to record logical changes for replication, archiving, and point‑in‑time recovery, highlighting their distinct layers, purposes, content, and write mechanisms.
The article compares Docker containers with traditional virtual machines across four core aspects—resource consumption, isolation mechanisms, startup speed, and deployment efficiency—showing that containers use shared kernels for lower memory and CPU overhead, provide process‑level isolation, start in under a second, and enable rapid CI/CD workflows.
This article provides a detailed reference of essential Nginx commands—including startup, shutdown, reload, configuration checks, process signaling, debugging, and monitoring—explaining their effects, typical use cases, and the underlying behavior of master and worker processes.
