Sharing over a decade of architecture experience from Baidu, Alibaba, and Tencent.
This guide presents practical MySQL optimization techniques—including SQL and index refinement, InnoDB and connection parameter tuning, cache layer integration, and architectural scaling with read‑write splitting and sharding—to dramatically increase query throughput and reduce latency.
This article explains how Kafka leverages sequential disk I/O, zero‑copy data transfer, OS page cache, and partition‑based parallelism to deliver massive throughput, detailing the underlying mechanisms, performance numbers, and a practical formula for estimating total system capacity.
This guide explains practical steps to eliminate Kafka backlog by enhancing consumer throughput, optimizing producer settings and message size, implementing flow‑control and back‑pressure, and tuning cluster resources and monitoring to ensure stable high‑performance streaming.
This article explains MySQL master‑slave replication, covering its purpose for high availability and read‑write separation, typical one‑master‑multiple‑slaves architecture, the binlog‑based synchronization mechanism, and the roles of the master’s dump thread and the slave’s I/O and SQL threads.
This guide explains how to maximize Nginx's concurrent handling capacity by configuring worker_processes, worker_connections, event settings, system limits, and I/O optimizations, providing concrete code snippets and kernel parameters for achieving tens of thousands of simultaneous connections.
This guide explains how to achieve million‑level concurrent request handling by combining Nginx, LVS, and Keepalived, detailing the architecture layers, load‑balancing design, high‑availability configuration, and practical sample configurations for each component in modern large‑scale web services.
This article explains Docker’s three fundamental OS‑level mechanisms—Namespaces, Cgroups, and UnionFS—detailing how they provide process, network, and filesystem isolation, resource management, and layered image storage for efficient container operation.
Single Sign-On (SSO) lets users authenticate once and automatically gain access to all trusted applications, eliminating repeated logins and streamlining user experience across heterogeneous systems such as e‑commerce, payment, and collaboration platforms.
This guide compiles the most frequently used Docker commands, covering version checks, image management, container lifecycle, network and volume operations, as well as cleanup techniques, providing a concise reference for developers working with cloud‑native container environments.
This guide explains how to avoid duplicate message consumption in Kafka by designing unique identifiers, implementing consumer-side idempotence with deduplication tables, leveraging Kafka’s transactional features, and establishing system-level safeguards and monitoring to ensure reliable, exactly‑once processing.
