Cross-Cloud Data Integration Strategies for Multi-Cloud Healthcare Enterprises: Architecture, Governance, and Operational Outcomes

Abstract

In the transition to multi-cloud computing, healthcare enterprises increasingly face the challenge of dealing with data silos across heterogeneous cloud environments. Technology for cross-cloud data integration is needed for real-time clinical access to patient data, enterprise analytics, and regulatory compliance in modern healthcare computing environments. The article presents architectural patterns, integration patterns, and governance frameworks for secure and scalable exchange of data between disparate public and private cloud platforms, such as federated data architectures, event-driven integration patterns, and standards-based healthcare APIs. HIPAA compliance, data sovereignty, and identity management requirements complicate security and governance across clouds. Healthcare interoperability standards enable the semantic interoperability of clinical data exchange: FHIR and HL7 are two examples. Implementation frameworks based on the phased implementation strategies were used to address the high-priority clinical workflows and the required technical and organizational change. These implementations resulted in improved data access, care coordination, and decision-support capabilities. The results provide guidance for health care systems regarding reconciling agility, compliance, and performance requirements in distributed cloud environments. Integration strategies are seen as key enablers for contemporary healthcare delivery, advanced analytics, and value-based care endeavors.
