Choreography

Using events to talk between services (also bounded contexts). Services interact independently. Event-driven approach.

Example of services that can help with choreography are Amazon SQS, Amazon SNS or Amazon EventBridge.

Orchestration

Flow of state that is normally controlled by the orchestrator. Think of flow chart or state machines. Might consider using orchestration within a bounded context. Normally follows request/response.

Example would be AWS Step Functions.
