The Big Friendly Monolith

Explore a conference talk that challenges the prevailing microservices trend by advocating for a "Big Friendly Monolith" approach. Delve into the complexities of breaking down existing monoliths and the substantial investment required for greenfield microservices projects. Learn about alternative architectural patterns, including CQRS, event sourcing, and the Axon Framework. Discover how to leverage these concepts to create a scalable, maintainable monolith that offers many benefits of microservices without the associated complexities. Gain insights into practical implementation details such as command gateways, event handlers, and asynchronous command buses. Engage with the speaker's Q&A session, addressing concerns about chatty commands, event delivery, time delays, data erasure, and migration strategies.
