Multi-tenant portal architecture
Shared core capabilities were standardized while insurer-specific process variants remained configurable and isolated.
Success Story
Portal platform for multiple statutory health insurers
A reusable component catalog and scalable architecture enabled consistent delivery of insurer-specific portals with strict security and patient-data compliance.
The platform combines Angular frontend delivery, Java/Spring Boot domain services, an abstraction data layer, Kafka-based event integration, SAP connectivity, and interactive Form.io journeys. It was designed for multi-tenant reuse across insurers while preserving domain-specific process differences.
Health insurance portal program context
Architecture and delivery scope
Angular component catalog
Reusable UI and process components accelerated delivery and ensured consistent UX and behavior across portals.
Java/Spring Boot service architecture
Domain services and API contracts were modularized for maintainability, testability, and controlled change.
Abstraction data layer
Backend system specifics were shielded behind a stable data abstraction, reducing coupling between portal UX and source systems.
Kafka event integration
Asynchronous process chains were implemented for resilient orchestration and better scalability under operational load.
SAP integration
Core data and process integrations with SAP were implemented with validation, monitoring, and operational fallback paths.
Interactive Form.io journeys
Rule-based dynamic forms supported complex application and service workflows with traceable data quality.
Initial situation
Multiple insurers with partially shared process models
The challenge was to maximize reuse without losing insurer-specific requirements.
High integration complexity across portal, SAP, and domain services
Data consistency and operational traceability were required across synchronous and asynchronous paths.
Strict regulation for security and patient data
Architecture and implementation had to align with German public-sector guidance, GDPR, and healthcare data protection constraints.
Scalability and stability requirements
The platform needed reliable operation at peak load with controlled rollout and low regression risk.
Implementation activities
Step 1
Target architecture and reference model
A domain-oriented architecture model defined clear boundaries for frontend, services, data abstraction, eventing, and integration.
Step 2
Reusable component catalog with governance
Components were standardized, versioned, and documented with usage rules to support cross-portal scaling.
Step 3
Security-by-design and privacy-by-design
Role-based access, data minimization, encryption, auditability, and API hardening were implemented as architecture defaults.
Step 4
Patient-data compliant process controls
Retention/deletion logic, purpose limitation, traceability, and permissions governance were embedded into delivery and operations.
Step 5
Industrialized integration and operations
Kafka/SAP integration flows, error handling, monitoring, alerting, and release discipline were productionized for sustainable operations.
