Introduction to Azure IoT Management
Azure provides a comprehensive suite of services designed to help you manage and scale your Internet of Things (IoT) solutions. From device connectivity and data ingestion to device management, monitoring, and business integration, Azure IoT offers robust tools for every stage of your IoT journey. This documentation provides an overview of the key Azure IoT management services and their capabilities.
Effective IoT management is crucial for ensuring the reliability, security, and efficiency of your connected devices. Azure's platform-as-a-service (PaaS) offerings abstract away much of the underlying infrastructure complexity, allowing you to focus on building innovative IoT applications.
Azure IoT Hub
Azure IoT Hub is a fully managed service that enables reliable, bidirectional communication between millions of IoT devices and an Azure solution backend. It acts as a central message hub for IoT data, providing device-to-cloud and cloud-to-device telemetry and command capabilities.
- Device Identity Registry: Securely manage device identities and authentication.
- Message Routing: Route device-to-cloud messages to various Azure services based on defined rules.
- Device Twin: Maintain state information for devices, enabling synchronization and management.
- Direct Methods: Invoke cloud-to-device commands directly on devices.
- Device Streams: Enable bi-directional streaming communication with devices.

Azure Device Provisioning Service (DPS)
Azure Device Provisioning Service (DPS) is a helper service for Azure IoT Hub that enables zero-touch, just-in-time provisioning of devices, without requiring manual intervention. It allows devices to securely connect to the right IoT Hub without needing operator access.
- Automated Provisioning: Securely and automatically provision devices at scale.
- Multiple IoT Hubs: Distribute devices across multiple IoT Hubs for load balancing and regional availability.
- Attestation Mechanisms: Supports X.509 certificates, TPM, and Symmetric keys for device authentication.
