Deconstructing Monoliths with Domain Driven Design - Rohit Kelapure, David Turanski, Rohit Sood
summary
Liberty Mutual breaks a BPM monolith into event-driven microservices using event storming to find bounded contexts, then a SNAP analysis and API‑first work to carve services (rating split into risk and premium). Implementation uses Spring Boot on Pivotal Cloud Foundry, an event bus plus an event store, an anti‑corruption layer and a saga orchestrator; Event Sourcing and CQRS power materialized views. A 10‑week Dojo produces a working, deployed microservice architecture from a 1.5M‑line legacy.
