TL;DR

Comprehensive guide covering three major architecture patterns—Layered, Hexagonal, and Clean—explaining their structure, implementation approaches, and when to use each. Includes visual diagrams and code examples to illustrate each pattern's design principles.

Signal

• Layered Architecture separates concerns into Presentation, Business, and Data layers with clear dependencies, making it simple to understand and implement
• Hexagonal Architecture (Ports & Adapters) inverts dependencies by placing the application core at the center, allowing multiple adapters for different interfaces without modifying the core
• Clean Architecture organizes code in concentric circles with the Dependency Rule: dependencies always point inward, maximizing flexibility and testability

What They're NOT Telling You

The article doesn't discuss trade-offs between patterns, performance implications, or how to migrate legacy systems between architectural styles. Real-world projects often need hybrid approaches that blend multiple patterns—this gap isn't addressed.
