This article explains the evolution from basic SaaS monoliths to cloud‑native microservices, detailing IAAS/PAAS/SaaS models, the concept of bounded contexts in domain‑driven design, and how architectural patterns such as clean, hexagonal, and onion layers help achieve modular, scalable systems.
This article explores how microservice architecture, guided by Domain‑Driven Design principles such as bounded contexts, aggregates, and context mapping, defines service boundaries, improves autonomy, and influences communication patterns, including event‑driven integration, synchronous APIs, and BFF strategies, while addressing consistency, scalability, and deployment challenges.
During the Chinese New Year, the author reflects on the declining state of Chinese football and draws parallels to large‑scale digital transformation projects, exploring how component‑based, cloud‑native architecture and domain‑driven design can address the complexities of enterprise business systems, improve modularity, and enable rapid, resilient evolution.
This article outlines a comprehensive e‑commerce system architecture that combines a large middle platform with a small front‑end, leveraging domain‑driven design, service‑oriented layers, cloud‑native deployment, and robust monitoring to achieve high scalability, flexibility, and reliability for complex transaction scenarios.
This article explains how microservice architectures differ from traditional service‑oriented designs, outlines key characteristics such as bounded contexts and autonomy, and shows how Domain‑Driven Design, context mapping, and event‑storming can be used to identify, model, and communicate clear service boundaries for resilient, scalable systems.
The article explains how the lack of Command‑Query Responsibility Segregation (CQRS) leads to unnecessary complexity, outlines the benefits of read‑write separation, presents a simple e‑commerce example, and summarizes Vladimir Khorikov’s three CQRS types and when to apply them.
