14. Advanced Developers Conference 14 | Software Architecture represents the set of significant decisions.
15. Advanced Developers Conference 15 |
16. Architecture Vision Advanced Developers Conference 16 | What? How?
17. Architecture Vision Advanced Developers Conference 17 | What? System context Constraints Quality goals (prioritized) Risks
18. Architecture Vision Advanced Developers Conference 18 | How? Big picture Concepts, patterns, principles Base technologies Hypotheses
19. Big design up front is dumb. Doing no design up front is even dumber. DAVE THOMAS Advanced Developers Conference 19 |
20. Advanced Developers Conference 20 | Accidental Technical Business
21. Danger Zone Advanced Developers Conference 21 | Microservices Platform, Language & Frameworks Conference Driven Design
22. Components & Interfaces • Exports interfaces • Imports interfaces of other components • Implementation is exchangeable (Principle of secrecy & information hiding) • Suitable as unit of reuse • Can contain other components (Composition) Advanced Developers Conference 22 | In addition to interfaces, the component is the essential unit of design, implementation and therefore planning
23. Software Blood Groups • 0: available everywhere, carefully tested & contains eternal truths of computer science • A: application or domain related • T: technology-oriented, independent of application • R: representation changes Advanced Developers Conference 23 | Avoid AT-Software!
24. Organizational complexity • Modularity • Macro Architecture • Anti-Viscosity • Roles Advanced Developers Conference 24 |

26. Wrap-up • Domain Driven Design • Technology is not an end in itself • Appropriateness: Boring is the new cool • Components & blood groups • Empirical Advanced Developers Conference 26 |
27. It seems that perfection is attained not when there is nothing more to add, but when there is nothing more to remove. ANTOINE DE SAINT-EXUPÉRY Advanced Developers Conference 27 |
