What is Edge Computing and how it differs from Cloud computing?
In: Technology
Cloud computing is using computers in the cloud to calculate things, so you send all your input data to the cloud, it calculates things, and you get the results back.
Edge computing is calculating a large portion of the necessary things already before uploading to the cloud, so that the amount of data (and thus both time and cost for data transfer) is minimized.
A popular example is video recognition. Without edge computing, you would stream the full video feed of a camera to the cloud, where it would be processed to identify things. With edge computing, the device with the camera would process what it sees, e.g. whether there is movement at all, and then crop the picture down to the relevant part, and then only transfer the really interesting parts to the cloud for further analysis.
