What is an Event? http: //www. news. com. au

Types of Events Discrete Series Independent Time based Report state change Context partitioned Report condition Actionable Analyzable https: //www. biztalk 360. com/integrate-2018 -resources/eventing-serverless-and-the-extensible-enterprise/

Event Driven vs. Event Sourcing Event Notification Broadcast state changes No expectation from consumer Decoupled logic https: //martinfowler. com/articles/201701 -event-driven. html Event Sourcing Persist state changes Auditability Replay capability
