IoT edge
In Chapter 1, Introduction to the IoT – The Big Picture, we briefly talked about the IoT edge and why we need an IoT edge cloud. In this chapter, we will dive deeper into the IoT edge cloud in terms of IoT edge location, hardware, and software.
IoT edge – location
The location where edge devices will be located is very important. The closer an edge device is to IoT endpoint devices or the source of the data, the more benefits you will get, such as very low latency and responsiveness.
The connectivity options used in an IoT solution play a critical role in choosing an edge location, as explained in Chapter 2, The "I" in IoT - IoT Connectivity. The communication range of the connectivity option used is what determines the location of the edge device – for example, some of the connectivity options we discussed in Chapter 2, The "I" in IoT - IoT Connectivity have a very limited range. In this case, the edge has to be very close...
