This article explores the fundamentals of software architecture, discussing entropy, the dual value of behavior and structure, core design principles such as SOLID, DRY, layering, orthogonality, component coupling, boundary definition, communication patterns, and modeling tools, while also offering practical guidance for building maintainable systems.
This article details Qunar's end‑to‑end digital quality measurement system, describing how over 100 indicators were defined, filtered, and organized into a hierarchical model, how the platform ingests and visualizes data, and how continuous governance and PDCA cycles improve system stability and reduce complexity.
This article explains Domain-Driven Design as a methodological approach for handling software complexity by aligning business, system, and organizational structures through modeling, detailing its core concepts, goals, key methods, and real‑world case studies from large‑scale systems.
Domain‑Driven Design is a methodological approach that refactors large, complex systems by aligning business language with architecture through metaphors, layering, refinement and abstraction, organizing code into high‑cohesion, low‑coupling bounded contexts, and applying strategic and tactical modeling—illustrated by Tencent Video case studies and contrasting lightweight versus rigorous practice styles.
This article introduces the fundamentals of enterprise architecture, defining its scope, reference models, and maturity stages, and explains how architects manage complexity, control costs, ensure SLA compliance, and apply iterative, partitioning, and simplification techniques to modernize enterprise IT systems.
This article explains why architecture design, especially Domain‑Driven Design, is essential for controlling the complexity, cost, and scalability of microservice systems, detailing common misconceptions, sources of complexity, and concrete steps to define clear domain and service boundaries.
This article explains that an engineer's primary responsibility is to solve business problems, explores the challenges across a product's lifecycle, outlines software complexity dimensions, and demonstrates how Domain‑Driven Design, strategic and tactical patterns, and modern architectural styles like Hexagonal and CQRS can effectively manage that complexity.
