Serverless is an event-based architecture, and what better scenarios than the IoT ones are event-driven? Thousands of devices that send telemetry to our solution and that we have to manage. In this session, we will see a simple approach to an IoT scenario that uses Durable Entities to handle the logic associated with our devices. A practical example to understand the Durable Entities technology's strengths and weaknesses that can be helpful in many scenarios where managing events is essential.
