Heterogeneous System Landscape

Challenge: Hospitals often operate numerous specialized systems with proprietary, non-standardized interfaces.

Solutions:

• Develop Custom Nodes for proprietary interfaces
• API wrapping for legacy systems without modern APIs
• Middleware approach with N8N as the central integration layer
• Use of HL7/FHIR adapters for medical standard interfaces

Availability and Reliability

Challenge: High availability must be ensured for critical workflows.

Solutions:

• Clustering setup with multiple N8N instances
• Load balancing for even load distribution
• Automatic failover in case of component failure
• Monitoring and alerting for proactive problem detection
• Disaster Recovery Plan with regular backups
