Building Monoliths that Could Scale (Easily) to Microservices (If They Need)
summary
Asserts that starting as a monolith using CQRS and DDD plus event-sourcing keeps design simple but makes extracting services trivial later. Shows a working conference chat demo: command handlers (aggregates) emit events to Axon Server, projections update query databases, queries return aligned views. Uses Axon Framework, Spring profiles and Docker to split the app into modules and run multiple instances; commands produce events and projections stay consistent, proving the approach works.
