# Layered architecture problems
37+
38+
* No clear application core

* Business logic leaks to the presentation layer

# Intent
48+
49+
* Application can be driven by users, programs, automated test or batch scripts
50+
* Application can be developed and tested in isolation from its eventual run-time devices and databases
51+
52+

53+
54+
# Applicability
55+
56+
Use Hexagonal Architecture pattern
57+
58+
* When the application needs to be independent of any frameworks
59+
* When it is important that the application highly maintainable and fully testable
60+
61+
---
62+
63+
# Concepts
64+
65+
* Ports are interfaces
66+
* The ports that drive the application are called primary ports
67+
* The ports that are driven by the application are called secondary ports
68+
69+
---
70+
71+
# Concepts
72+
73+
* Adapters are interface implementations
74+
* Typically different adapters for testing and production are provided
