A. Introduction

The Internet of Things (IoT) is a network of physical devices that connect to and exchange data with other devices and services over the Internet or other network. There are currently over ten billion connected devices in the world and more are added every year. Anything that can be embedded with the necessary sensors and software can be connected over the internet.

Azure IoT Hub is a managed service hosted in the cloud that acts as a central message hub for communication between an IoT application and its attached devices. You can connect millions of devices and their backend solutions reliably and securely. Almost any device can be connected to an IoT hub.

Several messaging patterns are supported, including device-to-cloud telemetry, uploading files from devices, and request-reply methods to control your devices from the cloud. IoT Hub also supports monitoring to help you track device creation, device connections, and device failures.

IoT Hub scales to millions of simultaneously connected devices and millions of events per second to support your IoT workloads. For more information about scaling your IoT Hub, see IoT Hub scaling. To learn more about the tiers of service offered by IoT Hub, check out the pricing page.

You can integrate IoT Hub with other Azure services to build complete, end-to-end solutions. For example, use:

IoT Central applications use multiple IoT hubs as part of their scalable and resilient infrastructure.

Each Azure subscription has default quota limits in place to prevent service abuse. These limits could impact the scope of your IoT solution. The current limit on a per-subscription basis is 50 IoT hubs per subscription. You can request quota increases by contacting support. For more information, see IoT Hub quotas and throttling. For more information on quota limits, see one of the following articles:
