Discovering the Ideal Definition of Edge Computing
Edge computing is a distributed IT architecture that processes and stores data as close to its source as possible, such as on local servers, IoT devices, or edge nodes, rather than routing all raw data to a centralized cloud. By keeping computation near the point of data generation, it minimises long-distance network travel, dramatically reducing latency, bandwidth consumption, and operational bottlenecks.
Upon searching for edge computing definition on different platforms, you will come across multiple entries. The most common definition of edge computing paints it as a distributed computing approach that involve shifting computing resources as close as possible to the source of data generation. It involves carrying out data processing tasks on or near the devices on the edge, thereby reducing network costs and latency requirements.
The “edge” in edge computing refers to any network endpoint near the data source, including routers, switches, local servers, IoT sensors, and integrated access devices. The defining requirement is physical or network proximity to the device generating data, rather than reliance on a distant central data center.
