Summary

There are millions of small devices connected to the internet, referred to collectively as the IoT. In this chapter, you learned about IoT and the components of IoT architecture. IoT is all about processing unstructured telemetry data from sensors and machines in high volumes and at speed. To handle such data, you need to have a scalable system, and you learned about IoT in the cloud with examples from AWS IoT services.

Devices are one of the central points when it comes to building IoT solutions. You learned about two major types of device software, including an MCU and an MPU, and methods to ingest these devices' data. You learned about the various techniques for controlling IoT devices, including device authentication, a device registry, and device management at scale, as well as the AWS IoT Device Management service. Security is the most pressing job, and it applies to IoT devices as well; you learned about various mechanisms for managing and securing IoT devices...
