Bounded Contexts and Domain-Driven Design concept
DDD strategic design: subdomain taxonomy (core/generic/supporting), bounded context definition, subdomains vs bounded contexts, physical/ownership boundaries, sizing heuristic (start wide), subdomain type evolution (all 6 transitions), growth management; Evans' originating treatment: Continuous Integration within context, false cognates vs duplicate concepts, context sizing trade-offs
Evolutionary Architecture concept
Three pillars; evolvability by style; strangler fig; six Rs; guidelines; antipatterns; DDD brownfield modernisation strategy; "form follows failure"; bad layering (horizontal coupling); component-based decomposition; decision loop speed and thrashing; service extinction; Farley: testability+deployability as operational drivers, TDD as architectural feedback, architectural descriptions as "tourist maps"
Team Topologies Model concept
Four team types (stream-aligned, platform, enabling, complicated-subsystem); three interaction modes with constraints/matrix; Dunbar-based team sizing; team API; one-owner-per-component rule; promise theory / SemVer; organisational sensing; discovery-to-establish pattern; topology evolution triggers; TVP; fractal platforms; Spotify model; DevOps anti-patterns
