Can you explain the concept of choreography in microservice interaction?

Choreography is an approach to organizing the interaction of microservices, where each service independently reacts to events published by other services, without a central coordinating component.

Instead of having a single orchestrator that manages the sequence of calls, services exchange messages (events) and decide themselves when and how to respond to them. This increases flexibility and reduces coupling between services.

Example: an order service publishes an "Order Created" event, the payment service listens to this event and initiates the payment process, the notification service sends an email to the customer, etc.

This approach is well-suited for systems with asynchronous interaction and event-driven architecture.
