Data Hub Architecture Overview

The NFDI4Immuno Data Hub has many components and routes of interaction. Still the data hub follows a three-layer architecture to separate concerns:

1. Client Layer: User-facing components. Handles all user interactions and presents data through various interfaces.
2. Portal Infrastructure: Core services and APIs. Provides the core functionality including API gateway, services, and databases.
3. Storage Layer: Data persistence and management. Manages persistent data storage including object storage and reference databases.

The full architecture diagram is available on Miro.

The architecture supports three primary user journeys:

• Submission Journey: Data validation and storage
• Search Journey: Data discovery and filtering
• Retrieval Journey: Data access and delivery
