Device configuration
In this section, we will cover the device configuration use case as an introduction to the edge device hub archetype pattern. You will learn the role and purpose of the infrastructure, platforms, and applications (collectively referred to as architectural elements going forward and shown in Figure 3.4) that support device operation at the edge. We will briefly discuss the benefits and drawbacks of placement decisions.
Rationale
The device configuration use case is meant to supplant legacy IoT architectures that connect fixed-function devices and embedded systems directly to a host in the cloud. Having a single platform for all devices puts the burden of device registration, protocol support, data collection, and analytics on one platform in one location. However, this approach required all data to be sent to the cloud if it wasn’t discarded, resulted in delayed analysis (thus delayed reaction times due to latency), and incurred data transfer and storage...
