Azure Reference Architecture

Notes

  • Azure Storage is used to store web portal assets, training data and models.
  • User authentication services (not shown in diagram) provided by Authgear, which can be hosted in the same cluster or as an external service.

Optional Training Pipeline

  • FormX training pipeline is based on Kubeflow. Hence the rights to create CustomResourceDefinitions (CRD) in the cluster is required.
