Let’s explore an example of what could happen if we combine what we just studied. Context: We need to build a program that manages IoT devices. We begin by creating two microservices: As a visual reference, the final system could look as follows (we cover the DeviceLocation microservice later):  Figure 19.8: Three microservices communicating using the Publish-Subscribe pattern  Here are the user interactions and the published events: {    “id”: “some id”,    “name”: “Device 1”,    “other”: “properties go here…”} In parallel, the Networking microservice must know when a device is created, so it subscribed to the DeviceTwinCreated event. When a new…
