Orchestrated communication

This process is similar to the asynchronous communication process that we discussed earlier. Orchestrated communication still uses message stores to transmit data; however, the Microservice sending the data would insert different messages in different queues in order to complete the action. For example, an Order Microservice would insert the message in the queue consumed by the Inventory Microservice and another message in the queue consumed by the Shipment Microservice:

The orchestration may be carried out by a separate component, which is known as Saga, which we will read more about in Chapter 8, Microservices Architectural Patterns.
