Azure Certified Device
Azure Certified Device certification validates that a device can connect with Azure IoT Hub and securely provision through the Device Provisioning Service (DPS). This certification reflects a device's functionality and interoperability, which are a necessary baseline for more advanced certifications.
IoT Plug and Play
IoT Plug and Play certification, an incremental certification beyond the baseline Azure Certified Device certification, validates Digital Twin Definition Language version 2 (DTDL) and interaction based on your device model. It enables a seamless device-to-cloud integration experience and enables hardware partners to build devices that can seamlessly integrate without the need to write custom code.
Edge Managed certification, an incremental certification beyond the baseline Azure Certified Device certification, focuses on device management standards for Azure connected devices. Today, this certification program focuses on Edge runtime compatibility for module deployment and management though will continue to grow in the future with additional customer manageability needs.
