# Layered architecture problems
|
|
|
|
|
|
|
|
|
|
* No clear application core
|
|
|
|
|
* Business logic leaks to the presentation layer

# Intent
|
|
|
|
|
|
|
|
|
|
* Application can be driven by users, programs, automated test or batch scripts
|
|
|
|
|
* Application can be developed and tested in isolation from its eventual run-time devices and databases

# Applicability
|
|
|
|
|
|
|
|
|
|
Use Hexagonal Architecture pattern
|
|
|
|
|
|
|
|
|
|
* When the application needs to be independent of any frameworks
|
|
|
|
|
* When it is important that the application highly maintainable and fully testable

|
|
* Ports are interfaces
|
|
|
|
|
* The ports that drive the application are called primary ports
|
|
|
|
|
* The ports that are driven by the application are called secondary ports
