Google Cloud Reference Architecture
(Link to download original Figjam file)
Notes
- Google Cloud 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.
