Summary
An introductory guide to five proven software architectural patterns — Layered (n-tier), Event-Driven, Microservices, CQRS, and others — explaining the role each layer or component plays and when to apply them. The article frames architecture as a blueprint that aligns team understanding with customer requirements.
介紹五種常見軟體架構模式：分層架構、事件驅動、微服務、CQRS 等，說明每種模式的結構與適用場景，幫助開發者在設計時選擇合適的組織方式。
Key Points
- Layered (n-tier): Components in horizontal layers, each depending only on the layer below — separates concerns cleanly but can cause performance overhead from traversing layers
- Event-Driven: Components communicate via events/messages rather than direct calls — enables loose coupling and async processing at the cost of debugging complexity
- Microservices: Each service owns its domain and is independently deployable — scales individual services but introduces distributed-systems complexity
- Architectural patterns are different from design patterns — they have broader scope and govern the whole system, not individual classes or functions
- Each pattern has tested trade-offs; choosing one means accepting its constraints, not just its benefits
Insights
Architectural choices are one of the hardest decisions to reverse in a project. This article doesn’t cover that the patterns aren’t mutually exclusive — large systems often layer them (e.g., microservices internally using layered architecture per service). The framing of “blueprint” is apt: you pick a pattern at the start, and it shapes what’s easy and hard for years.

Raw Excerpt
An architectural pattern is a general, reusable solution to a commonly occurring problem in software architecture within a given context. Architectural patterns are similar to software design patterns but have a broader scope.
