Event-driven architectures are a versatile approach to designing and integrating complex software systems. Event-driven architecture is not a new concept, but as more organizations evolve and are open to move more features to the cloud, this approach to system design has become appropriate in more situations and is worth a fresh look. In this session we'll talk about orchestrating enterprise workflows in the cloud using Event-driven approaches, how to build new services to participate, and design patterns for integrating existing/legacy applications. We'll also hit a few topics including: • Eventually consistent data and how to keep your data warehouse team happy • Command-Query Response Segregation • The Mediator design pattern • Event Sourcing
