Edge Computing & IoT

Sensors, Latency & the Cloud

1:00

How edge computing eliminates the cloud bottleneck by processing data close to the source, and how the edge–fog–cloud continuum is chosen by latency and bandwidth requirements.

By the end, you can

Explain why sending every IoT reading to the cloud creates a bottleneck.
Describe what edge computing does and why it cuts latency to single-digit milliseconds.
Name and explain the four drivers that motivate pushing compute to the edge.
Distinguish the Edge, Fog, and Cloud tiers by latency, compute power, and storage.
Apply the placement rule to decide whether a workload belongs at the edge or in the cloud.
Refute the two myths: edge-replaces-cloud and edge-is-automatically-secure.
Summarize the hybrid model: close for speed, central for scale.
