The first article in this edge computing series described a high-level edge computing architecture that identified the key layers of the edge including the device layer, application layer, network layer, and the cloud edge layer. In this article, we dive deeper into the application and device layers, and describe the tools you need to implement these layers.
As mentioned in the first article, the cloud edge is the source for workloads for the different edge layers, provides the management layer across the different edge layers, and hosts the applications that need to handle the processing that is just not possible at the other edge nodes due to limitations at these nodes.
The device layer consists of small devices running on the edge. The application layer runs on the local edge and has greater compute power than the device layer. Let’s dive into the details of each of these two layers and the respective components in the layers.
