Latency If the result must change an actuator, safety state, customer flow, or local user experience in tens of milliseconds, cloud-only processing is fragile. The edge can remove network distance from the decision path. Bandwidth Raw sensor, video, and machine data can overwhelm network links and storage budgets. Edge processing can summarize, filter, compress, or trigger selective upload so the cloud receives useful events instead of unbounded exhaust.
