In the world of microservices, effective communication is key. While CQRS and Event Sourcing are often introduced as advanced data management techniques, their real power lies in how they revolutionize messaging. By organizing event flows, these patterns simplify and streamline communication across distributed services. In this talk, Oliver will introduce CQRS and Event Sourcing from a fresh angle—focusing on how these patterns enable ordered, efficient communication in complex systems. No prior knowledge of CQRS or Event Sourcing is needed, as we’ll explore them through this unique lens, illuminating how these approaches naturally lead to clearer, more reliable service interactions.
