The Hive: Coding a Modular Monolith Ready for Microservices
summary
Shows how to refactor a legacy spaghetti monolith into a modular monolith that can later be split into microservices using the Hive pattern: combine multiple hexagonal architectures with vertical slicing to define clean module boundaries. Uses live coding to evolve a concrete Java/architecture codebase step-by-step from monolith spaghetti to a Hive-based modular monolith, then demonstrates extracting a module into a separate microservice.
