- Data is processed using Azure Data Factory, to be placed on Azure Data Lake.
- Data from Azure Data Factory is placed into the Azure Data Lake Storage for training.
- Data scientists train a model using Azure Machine Learning. The model is containerized and put into an Azure Container Registry.
- The model is deployed to a Kubernetes cluster on Azure Stack Hub.
- The on-premises web application can be used to score data that's provided by the end user, to score against the model that's deployed in the Kubernetes cluster.
- End users provide data that's scored against the model.
- Insights and anomalies from scoring are placed into a queue.
- A function app gets triggered once scoring information is placed in the queue.
- A function sends compliant data and anomalies to Azure Storage.
- Globally relevant and compliant insights are available for consumption in Power BI and a global app.
- Feedback loop: The model retraining can be triggered by a schedule. Data scientists work on the optimization. The improved model is deployed and containerized as an update to the container registry.
Key technologies used to implement this architecture:
- Azure Machine Learning: Build, deploy, and manage predictive analytics solutions.
- Azure Data Factory: Ingest data into Azure Data Factory.
- Azure Data Lake Storage: Load data into Azure Data Lake Storage Gen2 with Azure Data Factory.
- Container Registry: Store and manage container images across all types of Azure deployments.
- Azure Kubernetes Service (AKS): Simplify the deployment, management, and operations of Kubernetes.
- Azure Storage: Durable, highly available, and massively scalable cloud storage.
- Azure Stack Hub: Build and run innovative hybrid applications across cloud boundaries.
- Azure Functions: Event-driven serverless compute unit for on-demand tasks running without the needs of maintaining the computing server.
- Azure App Service: Path that captures end-user feedback data to enable model optimization.
With the Azure AI tools, edge, and cloud platform, edge intelligence is possible. The next generation of AI-enabled hybrid applications can run where your data lives. With Azure Stack Hub, bring a trained AI model to the edge, integrate it with your applications for low-latency intelligence, and continuously feedback into a refined AI model for improved accuracy, with no tool or process changes for local applications. This solution idea shows a connected Stack Hub scenario, where edge applications are connected to Azure. For the disconnected-edge version of this scenario, see the article AI at the edge - disconnected.
Potential use cases
There's a wide range of Edge AI applications that monitor and provide information in near real-time. Areas where Edge AI can help include:
- Security camera detection processes.
- Image and video analysis (the media and entertainment industry).
- Transportation and traffic (the automotive and mobility industry).
- Energy (smart grids).
