An IoT device is usually associated with some sensor or a device whose purpose is to measure or monitor the physical world. It does so asynchronously with respect to the rest of the IoT technology stack. That is, a sensor is always attempting to broadcast data, whether or not a cloud or fog node is listening. This is important, because the value of a corporation is in the data. Even if most of the data produced is redundant, there is always the opportunity that a significant event can occur. This is the data stream.
The IoT stream from a sensor to a cloud is assumed to be:
- Constant and never-ending
- Asynchronous
- Unstructured, or structured
- As close to real-time as possible
