Hexagonal Architecture in Monoliths and Microservices
summary
Hexagonal architecture isolates business logic from UI, DB and external services so unit tests cover most logic while integration tests exercise adapters and component tests exercise a whole monolith or microservice in isolation. Demo uses Java/Spring, HTTP gateways, message consumers (Kafka/Rabbit/RPC), and shows Testcontainers for realistic DB-backed component tests, fakes/mocks for other services, and cross-team contract testing for gateway implementations to catch mapping and protocol bugs.
