• You will see how DDD and CQRS can help define service boundaries
• You will be triggered to rethink how services should communicate in a microservices architecture

Domain Driven Design (DDD) and Command Query Responsibility Segregation (CQRS) are known to provide us with means to tackle complexity within an application. However, they also provide us with patterns and guidelines to manage the complexity of large scale, distributed environments

In this talk, we will take a DDD/CQRS approach on implementing Microservices, focusing on the messaging between them. We will discuss different approaches to ensure decoupling of services on the API level, but also ensuring flexibility to change the system's behavior at runtime simply by switching services on and off.
