Choosing cloud hosting for an ABA therapy app is not a generic DevOps decision — it is a compliance decision. Every server, database, and log stream that touches protected health information (PHI) must sit behind a signed Business Associate Agreement (BAA), encryption at rest and in transit, and access controls your OCR audit can defend.
This 2026 comparison evaluates AWS, Google Cloud Platform (GCP), Microsoft Azure, and Hetzner against the criteria ABA software teams actually care about: BAA availability, HIPAA-eligible services, compliance tooling, realistic pricing for a multi-location clinic platform, and honest trade-offs. We wrote this from production experience — TWO44 hosts HIPAA-compliant ABA platforms for clinics across North Carolina.
How We Evaluated HIPAA Cloud Hosting Providers
We scored each provider on five criteria that matter for ABA therapy applications storing session notes, behavior data, intake forms, and billing records:
- BAA availability — Can you sign a Business Associate Agreement before storing any PHI?
- HIPAA-eligible service breadth — How many core services (compute, database, storage, logging) are explicitly covered?
- Compliance tooling — Encryption defaults, IAM/RBAC, audit logs, key management, and configuration guardrails
- ABA workload fit — Multi-location scheduling, real-time data collection, file uploads (insurance cards, assessments), and parent portal traffic patterns
- Total cost of ownership — Monthly infrastructure for a typical 3-location ABA platform at 500–2,000 active clients
Reference architecture: client → API gateway → auth service → encrypted PostgreSQL → audit log store → BAA-covered third-party integrations. TWO44 deploys this pattern on AWS for ABA therapy platforms.
HIPAA Cloud Hosting Comparison Table (2026)
| Provider | BAA Available | HIPAA-Eligible Services | Compliance Strengths | Typical Monthly Cost* | Best For |
|---|---|---|---|---|---|
| AWS | Yes — via AWS Artifact | 140+ services (EC2, RDS, S3, Lambda, ECS, CloudWatch, KMS) | Deepest HIPAA service list; mature IAM; Config rules; extensive compliance documentation; most third-party healthcare integrations | $800–$2,500 | Production ABA platforms needing full PHI stack, multi-region, and vendor ecosystem |
| Microsoft Azure | Yes — Microsoft BAA | 60+ services (App Service, Azure SQL, Blob Storage, AKS, Key Vault) | Strong if your team already uses Microsoft 365; Azure Policy for compliance baselines; good hybrid/on-prem options | $700–$2,200 | Clinics on Microsoft stack; enterprises with existing Azure AD and compliance teams |
| Google Cloud (GCP) | Yes — for GCP services | 40+ services (GCE, Cloud SQL, Cloud Storage, GKE, Cloud KMS) | Clean IAM model; strong data analytics if you need reporting pipelines; good Kubernetes support | $650–$2,000 | Data-heavy ABA platforms with analytics dashboards; teams already on GCP |
| Hetzner | No — no BAA offered | Not HIPAA-eligible for PHI storage | Excellent price/performance for compute; simple VPS and dedicated servers; EU data residency | $50–$300 | Non-PHI workloads only: marketing sites, CI/CD runners, staging environments, static assets |
*Estimated monthly cost for a 3-location ABA platform (app servers, PostgreSQL, object storage, CDN, logging, backups). Actual costs vary by traffic, storage, and architecture. Hetzner estimate is for non-PHI tier only.
AWS — Best Overall for HIPAA ABA Platforms
AWS is the default choice for HIPAA-compliant healthcare applications in 2026, and for good reason. Enable the BAA in AWS Artifact, restrict deployments to HIPAA-eligible services, and you get the broadest toolkit for ABA-specific workloads:
- Compute: ECS Fargate or EC2 for the application layer; Lambda for async jobs (authorization checks, notification dispatch)
- Database: RDS PostgreSQL with encryption at rest (AES-256), automated backups, and Multi-AZ for clinic uptime
- Storage: S3 with server-side encryption for intake documents, insurance cards, and ADOS assessment files
- Security: KMS for key management, CloudTrail for audit logging, WAF for parent portal protection
- Monitoring: CloudWatch with log retention policies aligned to HIPAA's six-year documentation requirement
Honest downsides: AWS billing is complex; misconfigured S3 buckets are the #1 HIPAA cloud violation; not every AWS service is HIPAA-eligible — you must check the list before deploying.
TWO44 deploys ABA platforms on AWS with signed BAAs, encrypted PostgreSQL, and role-based access separating RBT, BCBA, and admin roles. See our Autizum case study for a live reference architecture.
Microsoft Azure — Strong for Microsoft-First Organizations
Azure offers a comprehensive BAA and HIPAA-eligible services that cover most ABA platform requirements. If your clinic or development team already runs on Microsoft 365, Azure AD, and Teams, the identity integration alone saves weeks of configuration.
- App Service or AKS for containerized ABA applications
- Azure SQL or PostgreSQL Flexible Server for encrypted patient records
- Blob Storage for document uploads with customer-managed keys
- Azure Key Vault for secrets and encryption key management
- Azure Monitor and Log Analytics for audit trails
Honest downsides: Smaller HIPAA-eligible catalog than AWS; Azure portal complexity; some healthcare SaaS integrations default to AWS-first.
Google Cloud — Solid for Analytics-Heavy ABA Platforms
GCP signs a BAA for covered services and provides a clean, developer-friendly platform. ABA organizations building custom analytics — goal progress dashboards, payer audit reports, multi-location KPI tracking — benefit from BigQuery integration without exporting PHI to non-eligible services.
- Cloud Run or GKE for application hosting
- Cloud SQL (PostgreSQL) with encryption and automated backups
- Cloud Storage for encrypted file uploads
- Cloud KMS for key management
- Cloud Logging with retention policies for audit compliance
Honest downsides: Fewer HIPAA-eligible services than AWS; smaller healthcare vendor ecosystem; fewer ABA-specific reference architectures available publicly.
Hetzner — Cost Leader, Not for PHI
TWO44 uses Hetzner for specific infrastructure workloads — and we want to be direct about where it fits. Hetzner does not offer a Business Associate Agreement and is not suitable for storing or processing PHI. Using Hetzner for patient records, session notes, or intake forms would be a HIPAA violation regardless of how well you configure encryption.
Where Hetzner excels in a HIPAA architecture:
- Marketing websites — Public clinic pages with no PHI (blog, service descriptions, contact forms that do not collect health data)
- CI/CD runners — Build pipelines that never touch production PHI
- Staging environments — Synthetic/de-identified test data only
- Static assets and CDN origin — Non-sensitive media and documentation
A hybrid architecture — HIPAA-eligible cloud (AWS/Azure/GCP) for PHI, Hetzner for non-PHI tiers — is a legitimate cost optimization strategy that TWO44 uses in production. The PHI boundary must be architecturally enforced, not just policy-documented.
Configuration Checklist for Any HIPAA Cloud Provider
Signing a BAA does not make your ABA app compliant. These configuration steps apply regardless of provider:
- Enable encryption at rest (AES-256) on every database and storage bucket containing PHI
- Enforce TLS 1.2+ for all data in transit; no HTTP endpoints
- Implement least-privilege IAM — RBTs, BCBAs, intake staff, and billing each get scoped roles
- Enable audit logging (CloudTrail, Azure Monitor, Cloud Logging) with tamper-resistant retention
- Block public access on all storage; use VPC/private networking for database connections
- Enable MFA for all admin and developer accounts
- Automate backup encryption and test restore procedures quarterly
- Document your architecture in a HIPAA risk assessment — OCR asks for this

Our Recommendation for ABA Therapy Apps
For production ABA platforms storing PHI: choose AWS. The BAA coverage, service breadth, healthcare integration ecosystem, and TWO44's production experience across North Carolina clinics make it the lowest-risk choice for multi-location ABA applications.
Choose Azure if your organization is already standardized on Microsoft 365 and Azure AD — the identity integration reduces operational friction.
Choose GCP if your platform is analytics-heavy and your engineering team has GCP expertise.
Use Hetzner only for non-PHI tiers — marketing sites, CI/CD, staging with synthetic data. Never store session notes, behavior data, or intake forms on Hetzner.

Frequently Asked Questions
HIPAA cloud hosting is cloud infrastructure configured to store and process protected health information (PHI) under a signed Business Associate Agreement. It requires HIPAA-eligible services, encryption at rest and in transit, access controls, and audit logging — not just any cloud server.
Yes. AWS offers a BAA through AWS Artifact covering 140+ HIPAA-eligible services including EC2, RDS, S3, and Lambda. You must enable the BAA, restrict deployments to eligible services, and configure encryption, IAM, and audit logging correctly.
No. Hetzner does not offer a Business Associate Agreement and is not suitable for storing or processing PHI. It can be used for non-PHI workloads like marketing sites, CI/CD runners, and staging environments with synthetic data in a hybrid architecture.
AWS is the recommended choice for production ABA platforms storing PHI due to the broadest HIPAA-eligible service catalog, healthcare integration ecosystem, and proven production deployments. Azure suits Microsoft-first organizations; GCP works for analytics-heavy platforms.
No. The BAA is necessary but not sufficient. You remain responsible for application-level security, role-based access controls, staff training, encryption configuration, and maintaining HIPAA policies and risk assessments.
