When to use which architectural style
Clean Architecture, the hexagonal architecture, and FCIS share a great deal of similarities that engineers may find hard to choose for their applications. The layers of these three architectural styles can be approximately mapped as follows:
| Clean Architecture | Hexagonal Architecture | FCIS |

| Use Case | Core / Domain / Port | Core |
| Interface Adapters | Adapters | Shell |
| Frameworks and Drivers | Adapters | Shell |
