Microsoft Azure IoT Edge is a cloud service that allows users to run cloud intelligence directly on their devices. This means that data processing and analysis can occur locally, reducing latency and bandwidth usage. It enables devices to act on data in real-time, making them smarter and more efficient. With Azure IoT Edge, developers can deploy and manage applications and services on edge devices easily. It supports various programming languages and integrates with other Microsoft Azure services, providing flexibility and scalability for businesses looking to enhance their Internet of Things (IoT) solutions.
