Selection Checklist

✅ Regulatory Constraints

HIPAA Eligibility: Verify tool supports BAA (AWS, Azure, GCP services), on-premise option if required
Certifications: Prefer tools with healthcare certifications (e.g., Epic-certified integration engines)
Data Residency: Ensure compliance with state-specific laws (e.g., data must stay in U.S.)

✅ Managed vs. Self-Hosted

Managed Services: Favor for rapid deployment, reduced ops burden (SageMaker, Snowflake)
Self-Hosted: Consider for data sovereignty, cost optimization, customization (HAPI FHIR, Kafka)
Hybrid: Managed control plane + self-hosted data plane (e.g., Databricks on customer VPC)

✅ Observability & Cost

Monitoring: Built-in observability (logs, metrics, traces) or integration with SIEM/APM
Cost Controls: Usage-based pricing (set budgets, alerts), reserved capacity for predictability
Vendor Lock-In: Prefer open standards (FHIR, DICOM, Kafka) to enable migration

Conclusion

Tool selection balances project needs, compliance requirements, team skills, and vendor lock-in risk. Favor managed services for speed, open-source for flexibility, and healthcare-specific tools for domain fit.
