Message Oriented Microservices

In the previous chapters of this book, you saw microservices interacting with each other and human actors (end users) interacting with the edge microservice using a client device (a browser). Because microservices are “micro” in nature, multiple microservices must often communicate with each other to meet useful business functionalities. These inter-microservices communications can be within a business domain or across business domains. This chapter introduces message-oriented microservices, whereby microservices can communicate over messaging backbones.
