IoT devices produce many types of information, including telemetry, metadata, state, and commands and responses. Telemetry data from devices can be used in short operational timeframes or for longer-term analytics and model building. (For more on this diversity, read the overview of Internet of Things.)Many devices support local monitoring in the form of a buzzer or an alarm panel on-premises. This type of monitoring is valuable, but has limited scope for in-depth or long-term analysis. This article instead discusses remote monitoring, which involves gathering and analyzing monitoring information from a remote location using cloud resources.
