OReilly SACON2018 - Events on the outside, on the inside, and at the core

Events are very much on the edge of traditional applications, which use them as an application integration mechanism. The classic example is an ecommerce system. When a customer places an order, the order management application publishes an event, which triggers the fulfillment application to action. But today, microservices and DDD—which is a great foundation for microservices—are at the core of the application. Events play an essential role in modern applications. Chris Richardson explains why events are a key application integration mechanism and how they are used by applications to communicate with the outside world. You’ll learn how the microservices inside an application use events to maintain data consistency and discover how to go one step further and make events an integral part of your domain logic.
