IoT architecture

Before getting into Azure and its features and services regarding IoT, it is important to understand the various components that are needed to create end-to-end IoT solutions.

Consider that IoT devices across the globe are sending millions of messages every second to a centralized database. Why is this data being collected? Well, the answer is to extract rich information about events, anomalies, and outliers that are to do with whatever those devices are monitoring.

Let's understand this in more detail.

IoT architecture can be divided into distinct phases, as follows:

1. Connectivity: This phase involves a connection being made between a device and the IoT service.
2. Identity: After connecting to the IoT service, the first thing that happens is the identification of the device and ensuring that it is allowed to send device telemetry to the IoT service. This is done using an authentication process.
3. Capture: During this phase, the device...
