When the order microservice sends a message to multiple fulfillment microservices to coordinate the packing and shipping of an order is an example of one-to-many asynchronous communication in an e-commerce application. 

In this scenario, the order microservice sends a message to multiple fulfillment microservices to coordinate the process of packing and shipping an order to a customer. 

Each fulfillment microservice receives the message, processes it, and sends a confirmation message back to the order microservice. This process involves one-to-many asynchronous communication.
