Cloud vs Edge Computing, Explained Simply
"Cloud" and "edge" describe where computing happens — and the distance between the two has real consequences for speed and reliability.
The cloud: powerful but distant
Cloud computing runs your workload in large, remote data centres with enormous capacity. It is ideal for heavy processing, storage and anything that benefits from scale. The catch is distance: every request travels to and from that data centre, adding delay.
The edge: close but constrained
Edge computing moves processing nearer to where data is generated — a factory floor, a shop, a phone. That cuts latency and keeps working even if the wider network hiccups, which matters for things like sensors and live video. The limit is capacity: edge devices are smaller. Real systems usually combine the two, handling time-critical work at the edge and sending the rest to the cloud.
