When thinking about an Event, consider 2 cases.

1. When computer programs talk to each other.
2. When a person is executing a business process.

Imagine a new order is placed in an online store. The order details are published as an event, triggering other programs to execute processes like inventory updates, payment processing, and shipping.

When an event is published, it's made available to any program that wants to get it, ensuring all necessary components are informed and can act accordingly. This enables a flexible system where each program can be managed and operated separately from all the others.

An event is also a fact that occurred in a process or within a business context.

e.g. A customer's payment is received—this is an event that represents a factual update to the business process, such as updating the customer's account balance or triggering order fulfillment.

Efficiency: Events drive real-time processing, ensuring systems react immediately to changes.

Scalability: By decoupling programs, event-driven systems can scale separately, meaning computer resources can be allocated to each capability per their own workloads.

Understanding events as both messages and business facts is key to leveraging Event-Driven Architecture for responsive, scalable, flexible, and efficient systems.

When we collaborate about the events that happen, we also build higher-quality software that genuinely meets the needs of it's users.
