Ports and Adapters (Hexagonal Architecture), Explained with Two Real Codebases
Explains how ports, adapters, and a registry keep business logic independent from vendors, making payment, email, and frontend API changes cheaper and easier to migrate.

Dependency Inversion vs. Dependency Injection
The article distinguishes dependency inversion as a principle that favors abstractions over concrete implementations, and dependency injection as a pattern that supplies those dependencies at runtime.
