What is legacy IoT architecture?
In this section, we will cover legacy IoT architectures: their purpose, promise, and fundamental drawbacks. You will learn why IoT has provided value to business executives, where it was heading as a natural technological progression before being superseded by edge computing, and reasons why it may not have been adopted as widely as initially anticipated.
A bit of history
Large commercial IoT networks became a viable solution for business with the convergence of cheap, low-power embedded processors and inexpensive, ubiquitous cellular data transmission. At that point, it became less expensive to transmit data from sensors than to have humans visit the sensors and record the data manually. However, the data was still tabulated and stored in central locations – a data center (DC) or, eventually, the cloud.
That approach and those needs formed the basis for initial IoT architectures, which connected devices over transmission networks directly...
