HIPAA Compliance Cloud Migration: Secure Architecture Without Slowing Care Delivery

Design around PHI data flow first

Map where PHI is created, transformed, stored, and transmitted. Data flow visibility should guide architecture decisions.

Implement control layers that auditors can verify

Controls must be testable and documented, including access restrictions, logging, encryption posture, and incident response process.

• Encryption in transit and at rest
• Role-based access with periodic recertification
• Immutable audit logging for sensitive transactions
• Backups with tested restoration procedures

Sequence migration in patient-safe phases

Avoid full cutovers for critical systems. Move services in low-risk increments and validate each phase.

Use rollback planning and parallel monitoring to reduce operational risk.

Treat BAA and vendor governance as core architecture

Business Associate Agreements and third-party risk controls are part of HIPAA readiness.

Your cloud security posture is only as strong as your integrated vendors.
