Before we start exploring different capabilities to support a real-life scenario, we will briefly explain the scenario we will use throughout this chapter.
IoT, Inc. is a fictitious start-up company that is planning to build solutions in the Internet of Things domain. The first solution they will build is a registration hub, in which IoT devices can be registered. These devices can be diverse, ranging from home automation devices to devices that control traffic lights and street lights. The main use case for this solution is offering the capability for devices to register themselves against a hub.
The hub will be built with DocumentDB as its core component and a web API to expose this functionality. Before devices can register themselves, they need to be whitelisted in order to prevent malicious devices from registering.
In the following screenshot, we see the high-level design of the registration requirement:
