A method comprising: receiving a sensor data stream from a first physical sensor over a first network connection type at a data ingestion agent of an edge platform system; from the data ingestion agent, delivering the ingested stream data to a data bus of the edge platform system; enriching the ingested stream data in real time through a data enrichment component of the edge platform system by performing an enrichment action on the ingested stream data, wherein the enrichment action comprises one or more of decoding the ingested stream data, decorating the ingested stream data with metadata, and normalizing the ingested stream data; making the enriched ingested data available on the data bus; processing the enriched ingested stream data at an analytics engine of the edge platform system that is subscribing to data from the data bus, wherein the processing comprises applying to the enriched ingested stream data in real time a first function specified by selected analytic expressions of an expression language and generating in real time a stream of data comprising intelligence information, wherein the first function comprises at least one of a transform, pattern detection, dynamic calibration, signal processing, math expression, data compaction, data analytic, data aggregation, rule expression, sending alert, and service invocation; publishing the intelligence information on the data bus, wherein the publishing comprises storing the intelligence information on the edge platform system in a rolling time-series database indexed by time for use by applications executable on the edge platform system; and determining based on the intelligence information whether to take selected action in a local network on a hardware device being monitored by the first physical sensor and whether to transmit at least a portion of the intelligence information to a wide-area network for processing, wherein the selected action comprises sending an alert to an operator on making a proactive action on a hardware device being monitored by the first physical sensor. receiving a sensor data stream from a first physical sensor over a first network connection type at a data ingestion agent of an edge platform system; from the data ingestion agent, delivering the ingested stream data to a data bus of the edge platform system; enriching the ingested stream data in real time through a data enrichment component of the edge platform system by performing an enrichment action on the ingested stream data, wherein the enrichment action comprises one or more of decoding the ingested stream data, decorating the ingested stream data with metadata, and normalizing the ingested stream data; making the enriched ingested data available on the data bus; processing the enriched ingested stream data at an analytics engine of the edge platform system that is subscribing to data from the data bus, wherein the processing comprises applying to the enriched ingested stream data in real time a first function specified by selected analytic expressions of an expression language and generating in real time a stream of data comprising intelligence information, wherein the first function comprises at least one of a transform, pattern detection, dynamic calibration, signal processing, math expression, data compaction, data analytic, data aggregation, rule expression, sending alert, and service invocation; publishing the intelligence information on the data bus, wherein the publishing comprises storing the intelligence information on the edge platform system in a rolling time-series database indexed by time for use by applications executable on the edge platform system; and determining based on the intelligence information whether to take selected action in a local network on a hardware device being monitored by the first physical sensor and whether to transmit at least a portion of the intelligence information to a wide-area network for processing, wherein the selected action comprises sending an alert to an operator on making a proactive action on a hardware device being monitored by the first physical sensor.
