Needless to say that the current hype around the Internet of Things IoT is huge. It seems like every day a new company announces some IoT enabled product. And with it some biased prediction of where the market is going. Instead of making yet another biased prediction, we measured what the really popular Internet of Things applications are right now.
Hardware serial number State information State information describes the current status of the device, not of the environment. It is updated, but usually not frequently.
Telemetry Data collected by the device is called telemetry. This is the eyes-and-ears data that IoT devices provide to applications. Telemetry is read-only data about the environment, usually collected through sensors.
Each source of telemetry results in a channel. Telemetry data might be preserved as a stateful variable on the device or in the cloud.
Although each device might send only a single data point every minute, when you multiply that data by a large number of devices, you quickly need to apply big data strategies and patterns. Commands Commands are actions performed by a device. Commands often have traits that constrain the choices available in your implementation.
Commands are not easily represented as state data. Commands are often not idempotent, which means each duplicate message usually results in a different outcome.
Like messaging systems, the implementation of a command function determines the delivery semantics, such as "at least once" or "exactly once". The command mechanism can include a return value, or might rely on the confirmation being made through a separate return message or by reflecting the expected change in the state data.
Commands might be of limited temporal relevance, so they should include a time-to-live TTL or other expiration value. Examples of commands include: Spin degrees to the right. Run self cleaning cycle.
Increase the rate by ten percent. Operational information Operational information is data that's most relevant to the operation of the device as opposed to the business application. This might include things such as CPU operating temperature and battery state.
This kind of data might not have long-term analytical value, but it has short-term value to help maintain the operating state, such as responding to breakages and correcting performance degradation of software after updates.
Operational information can be transmitted as telemetry or state data. Devices It's not always clear what constitutes a device. Many physical things are modular, which means it can be hard to decide whether the whole machine is the device, or each module is a discrete device.
There's no single, right answer to this question. As you design your IoT project, you'll need to think about the various levels of abstraction in your design and make decisions about how to represent the physical things and their relationships to each other. The specific requirements of your application will help you understand whether something that generates information should be treated as a device, and therefore deserves its own ID, or is simply a channel or state detail of another device.
