DEFINITION OF EDGE COMPUTING
Edge computing is a distributed computing close to
the sources of data.
Edge computing infrastructure includes
Edge devices connecting external objects to collect data
Edge servers to process data in real time onsite
It forms a localized system with data collection and
processing capabilities near the data source.
By doing so, it avoids the need of large quantity data
transmission between data source and centralized
cloud, thus providing fast response.
