The hardest part of microservices: your data

Conference

In this talk, we'll explore these problems and see how Domain Driven Design helps grapple with the domain complexity. We'll see how DDD concepts like Entities and Aggregates help reason about boundaries based on use cases and how transactions are affected. Once we can identify our transactional boundaries we can more carefully adjust our needs from the CAP theorem to scale out and achieve truly autonomous systems with strictly ordered eventual consistency. We'll see how technologies like Apache Kafka, Apache Camel and Debezium.io can help build the backbone for these types of systems. We'll even explore the details of a working example that brings all of this together.
