Once DTDL models are defined and deployed to the service instance, developers instantiate distinct "Digital Twins" from those templates. By configuring the defined in your DTDL files, individual nodes hook together to create an interactive topology mapping real-world workflows. Ingestion Pipelines
Digital twins remain static without data ingestion loops. Live metrics from field components route into , which broadcasts telemetry down to processing engines like Azure Functions . The function uses the Azure SDK to apply property patches or update runtime values dynamically across corresponding nodes in your twin graph.
