A petrochemical facility must issue emission alerts within 15 minutes of a threshold exceedance. Two architectures are evaluated: a cloud-only design (readings sent to the cloud every minute, cloud checks thresholds, alert issued via cloud notification; total latency 2 to 5 minutes) and an edge-assisted design (edge server checks thresholds locally on every reading, alert issued directly; total latency 10 to 30 seconds). Both meet the 15-minute requirement under normal conditions. Why was the edge-assisted design chosen?

Question

Accepted Answer

The edge design continues checking thresholds and issuing alerts even during an internet outage, while the cloud-only design would fail to detect exceedances during connectivity loss, creating a compliance gap

Answer

The edge design uses more accurate threshold values because they are configured locally

Answer

The edge design produces alerts faster, and speed is the only factor that matters in regulatory compliance

Answer

The edge design costs less to operate because it transmits less data to the cloud
