Healthcare cloud selection is governed less by raw compute price than by how a provider handles protected health information. The platforms that win in this category sign a Business Associate Agreement (BAA) by default, publish a wide catalogue of HIPAA-eligible services, hold HITRUST and FedRAMP attestations over the infrastructure they control, and offer purpose-built healthcare services for clinical data. This ranking compares the six providers most often shortlisted by US health systems, payers and digital-health companies, scored on BAA scope, healthcare-specific services, audit and access controls, and the shared-responsibility burden they place on the customer rather than on headline list price.
The first filter is the Business Associate Agreement. A provider must sign a BAA before any protected health information touches its services, and the practical differentiator is how many services are HIPAA-eligible under that BAA. AWS publishes the largest list at 166-plus services; Azure covers its BAA by default in the Microsoft Product Terms; Google Cloud and Oracle Cloud also sign BAAs. The risk for new teams is that placing PHI in a non-eligible service silently breaks compliance, so the eligible-service list, not the BAA alone, should drive architecture.
The second filter is healthcare-specific services and certifications. Azure Health Data Services and Microsoft Cloud for Healthcare, the AWS HealthLake and Comprehend Medical family, and the Google Cloud Healthcare API each accelerate FHIR, HL7v2 and DICOM handling far beyond generic storage and compute. HITRUST and FedRAMP attestations matter, but only cover the infrastructure the provider controls; IAM configuration, encryption, logging and incident response remain customer responsibilities and are in scope during a HITRUST audit. Buyers should map these shared-responsibility boundaries before signing.
The third filter is fit to the existing estate. Health systems standardised on Microsoft and Epic gravitate to Azure; data-and-analytics-led digital-health firms often prefer Google Cloud and BigQuery; Oracle Health customers find OCI natural.
