Platform Events are a Salesforce-nativefeature that enable apps to communicate inside and outside of Salesforce using an event-driven messaging architecture. An event producer creates an event and adds it onto the event bus, which operates as a queue with a strict chronological order. An eventconsumer subscribes to an event and gets notified when the event is put onto the event bus.

According to3, Platform Events can be used to defineand manage custom notifications within the Salesforce platform and in external apps. They can also be used to integrate Salesforce with external systems and devices in near real-time.

Therefore, a Solution Architect should suggest utilizing Platform Eventsbased on the devices' state change. This way, UC can connect the data from the smart devices to Salesforce in a scalable and reliable manner, without having to poll or query for changes constantly. UC can also use Platform Events to trigger workflows or actions based on the device status, such as creating a case, sending an email, or ordering a replacement part.
