Which IoT subsystem consumes data, integrates with business processes, and places the data in storage?

The correct answer is stream processors, as they play a critical role in consuming data generated by IoT devices, integrating this data with various business processes, and ultimately directing it to the appropriate storage solutions. Stream processors allow for real-time data processing and analysis, enabling businesses to derive actionable insights from incoming data streams.

Stream processors work by taking continuous input from data sources, processing it using specified logic or algorithms, and then outputting the results either back to a cloud service or to a storage solution. This capability is essential for applications that require immediate responses or actions based on the incoming data, such as alerting systems or real-time dashboard updates.

In contrast, IoT devices are primarily responsible for collecting and transmitting data rather than processing it. The cloud gateway service acts as an intermediary for data transmission but does not engage in data integration or large-scale processing. The user interface is focused on presenting the data to end users, rather than handling the backend processing tasks. Thus, stream processors uniquely fulfill the role of consuming, integrating, and storing data within an IoT architecture.
