2021 12-03 TOGAF for Developers
- 1. TOGAF (The Open Group Architecture Framework) for Developers Ryan M. Harrison Chief Software Architect December 3, 2021
- 2. What is Architecture? 2 The fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution. ISO/IEC 42010:2007 The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time.
- 3. 3 Architects maintain design principles https://we.letgo.com/blog/event-oriented-architecture-anti-patterns ...and the Dev said: I don’t need no stinking (know-nothing) Architect!
- 4. 4 Architects define System boundaries Level 1 Level 2 Level 3 Level 0 Enterprise Architect System Architect Software Architect Scope Detail
- 5. 5 System boundaries > Enterprise Architect
- 6. 6 System boundaries > Enterprise Architect
- 7. 7 System boundaries > Enterprise Architect Program A Program C Program B
- 8. 8 System boundaries > Enterprise Architect Program A Program C Program B System Boundaries
- 9. 9 System boundaries > System Architect System Boundaries Component A.1 Component B.2
- 10. 10 System boundaries > System Architect System Boundaries Requirements ⇒ Tech Selection Requirements ⇒ Design Decisions - Cluster config (e.g. replication) - Data serialization - Message schema - Channel structure Component A.1 Component B.2 Durable Message Queue

What isTOGAF? ● TOG: The Open Group ● AF: Architecture Framework ○ Structure ○ Method/Process (inc. governance) ○ Set of tools (e.g. specific techniques) ○ Building blocks 12 Relationship between TOGAF, COBT, ITL and PMBOK https://medium.com/@arindey/enterprise-architecture-frameworks-togaf-itil-cobit-pmbok-88a3e4dca82c
- 13. What is Enterprise Architecture? ● Enterprise: Collection of organizations with common goals ● Architecture: Structure of components; their inter-relationships; principles and guidelines for evolution 13
