When you aggregate messages, you combine a number of response messages from the invocation of one or more services into a single message. When you broadcast messages you send notification to the service and do not expect a response.

Before you begin

The most common way to aggregate messages is to use Fan Out and Fan In primitives in combination. Another way to aggregate messages is to perform a chained aggregation using Service Invoke. You broadcast messages using the Fan Out primitive.
