Edge devices are no longer just a supporting layer in IT architecture—they are becoming the frontline of computation. While cloud computing dominated the last decade, the next wave of innovation is clearly shifting toward distributed intelligence at the edge.
The reason is simple: data is being generated faster than centralized systems can efficiently handle it.
According to enterprise cloud providers like Amazon Web Services, edge computing enables processing “close to the devices that generate data,” improving real-time responsiveness and reducing the costs of transmitting large volumes of data to the cloud.
