Why do many smart devices use edge computing instead of sending all data to the cloud?

Asked on Oct 08, 2025

Answer

Edge computing is widely used in smart devices to process data locally, reducing latency and bandwidth usage while enhancing privacy and security. By performing computations at the edge, devices can make real-time decisions and minimize the amount of data sent to the cloud, which is crucial for applications requiring immediate responses, such as IoT-enabled industrial automation or smart home systems.

Example Concept: Edge computing allows smart devices to process data closer to the source, reducing the need for constant cloud communication. This approach decreases latency, conserves bandwidth, and enhances data privacy by keeping sensitive information local. It is particularly beneficial in scenarios where real-time processing is critical, such as autonomous vehicles, smart grids, and health monitoring systems, where immediate feedback and decision-making are essential.

Additional Comment:

Edge computing reduces the load on cloud infrastructure by processing data locally.
It enhances security by limiting the exposure of sensitive data to external networks.
Local processing enables faster response times, crucial for time-sensitive applications.
Reducing data transmission to the cloud can lower operational costs and improve efficiency.
