Strategic Goals Architectural
Principles Design and Delivery
Practices
Enable scalable business More customers/transactions Self-service for customers
Support entry into new markets Flexible operational processes New products and operational processes
Support innovation in existing markets Flexible operational processes New products and operational processes
Reduce inertia Make choices that favour rapid feedback and change, with reduced dependencies across teams.
Eliminate accidental complexity Aggressively retire and replace unnecessarily complex processes, systems, and integrations so that we can focus on the essential complexity.
Consistent interfaces and data flows Eliminate duplication of data and create clear systems of record, with consistent integration interfaces.
No silver bullets Off the shelf solutions deliver early value but create inertia and accidental complexity.
Standard REST/HTTP
Encapsulate legacy
Eliminate integration databases
Consolidate and cleanse data
Published integration model
Small independent Services
Continuous deployment
Minimal customisation of COTS/SAAS
