Understanding Orchestration and Choreography

Orchestration involves a central component that takes responsibility for the entire workflow, ensuring that the right services are called based on prerequisites. In orchestration, commands are used to instruct services, and events are used to publish that an event has occurred. On the other hand, choreography does not have a central orchestrator. Services in a choreography style react to events and work in a more decentralized manner, with each service playing off and reacting to each other. Choreography relies more on events and is typically seen in systems with looser coupling, while orchestration is used in more tightly coupled systems.
