This document discusses various types of architecture including enterprise, solution, integration, software, business, and domain architecture. It also outlines key architecture principles and deliverables. The principles include target architecture, roadmap, view models, patterns used in the solution, peer review, and governance. Key deliverables include documentation of these principles, various views of the system, and references. Maintaining architecture is important to enable the solution, ease implementation through patterns and alignment, and support the system post-deployment through quality attributes.

Frayed Edges - Architecture In Practice

- 2. Architecture is about categorisation, Separation of Concerns and making decisions Explicit

- 13. As an Enabler
- 14. Part of The Solution • Metaphor • Architecture + Domain Design • Ease Implementation • Architectural Patterns • Alignment • Better After-Life • Quality Attributes, SLAs
- 15. Part of The Team • Project Plans/Sprint Plans/etc • Architecture • Domain Driven Design • UX • Development Teams • Deployment and Support Teams
- 16. Part of Larger Group • Solutions are part of a larger group • Conform to the idioms and Practice of the group • Consistency across a Portfolio • Economies of scale for delivery, support, maintenance
- 17. The Quality Attributes • Security • Performance • Scalability • Resilience • Recoverability • Address CAP
- 19. Principles • Form the aims of the system • Can be Business, Functional, Technical or Deployment • any technical decision must conform to them • If any decision deviates, change the principle or note why the deviation
- 20. Target Architecture and Roadmaps ‣ Impact of Architecture - ‣ 3-5 years in advance Architecture as an enabler ‣ Roadmap aligned to ‣ Technical boundary, forms Delivery cycles part of principles and solution approach ‣ 6-12 month duration, typically ‣ Each decision is made as part of context of target architecture ‣ Target architecture is desired state, never achieved
- 21. Views Why? How? What? Where? Implementation Deployment Business View Functional View View View •Work with Business •Identify main The software (or • The physical to support their components and process) realisation of business Level interactions components will be The Solution Architecture •Services can be used to meet the •In practice Business derived from here functional • Machines, Architects work in the •not focused on requirements networks, Tech organisation implementation aspects software installations
- 22. Architectural Patterns ‣ Identify the Common patterns used in the solution ‣ Commonality can be reused Principle of Orthoganality ‣ Ease implementation
- 23. Peer Review • Technical review of solution, roadmap • other architects, not part of product • feedback to technical solution • part of governance and alignment
- 24. Governance • Part of Enterprise Architecture Role • Adhere to corporate and industry technical standards • Application Rationalisation • Ball of Mud to Clarity!
- 25. Pitfalls
- 26. Avoid • Architecture becoming a book keeping exercise - it’s not about box ticking • Ivory Tower architects - the architect is part of the team • Polishing door knobs • Architecture for Architecture’s sake • too many components, too finely granular services

- Architecture as an enabler\n- Percolator at google: \n* big change to core architecture and offering, \n* addressed a quality attribute: time to update \n* enable more features - eg previews\n- Amazon and services\n- by adopting a services based approach, allows amazon to offer it’s services to en users/customers\n\nReal world Use:\n different Frameworks\n- TOGAF\n- Zachman\n- UML\n- etc \n
- \n
- Use software frameworks to enforce architecture\n- eg MVC \n- Spring WebFlow\n- frameworks can maintain the principles \n* eg a principle could be to allow addition of new functionality without bringing the system down. In implementation, use OSGi\n
