What is edge computing with example

Edge computing is a distributed computing paradigm that brings data processing closer to the source of the data, reducing latency and improving real-time processing capabilities. This approach is particularly useful in IoT (Internet of Things) applications, where devices generate vast amounts of data that need to be processed quickly and efficiently. By moving data processing to the edge, organizations can reduce the amount of data that needs to be transmitted to the cloud or a central data center, resulting in significant cost savings and improved performance.

1. The Rise of Edge Computing

The growth of IoT devices has led to an explosion of data being generated at the source of the data, rather than in a centralized data center. This has created a need for more efficient and effective data processing capabilities that can handle the volume, velocity, and variety of this data. Edge computing addresses this need by bringing data processing closer to the source of the data, reducing the latency and improving the real-time processing capabilities of IoT applications.
