Multi-Cloud Strategy for a National Health Insurer
We re-platformed a national health insurer onto a resilient AWS and GCP multi-cloud architecture, cutting infrastructure cost by up to 45% while reaching 99.9% uptime and full HIPAA compliance.
Results at a glance
The situation
A national health insurance provider ran patient records, claims processing, and digital care delivery for patients, providers, hospitals, and internal teams across multiple regions. Its single-provider infrastructure buckled under peak patient traffic, causing frequent performance degradation and downtime. Expensive hardware maintenance and continuous upgrades drove up operational cost, while vendor lock-in, weak disaster recovery, and fragmented systems made HIPAA compliance difficult to sustain.
Eliminate performance bottlenecks and downtime risk without deepening dependence on any single cloud vendor. Deliver an architecture that scales elastically with demand, hardens disaster recovery, and enforces HIPAA-grade security and auditability across every layer.
How we delivered
Design a dual-cloud reference architecture
We mapped every workload to paired services on AWS and GCP, so each tier could serve traffic from either provider and fail over automatically when one degraded, removing the single point of failure.
Build an auto-scaling data and storage layer
Patient and claims data moved to Amazon RDS with Google Cloud SQL, while medical records were stored on Amazon S3 and Google Cloud Storage with automated backup, recovery, and durable object retention.
Distribute traffic and content globally
Amazon API Gateway and Google Cloud Load Balancing spread requests across services and regions, and Amazon CloudFront with Google Cloud CDN cached content near users to absorb peak load.
Unify identity and access control
We federated authentication through Amazon Cognito and Google Cloud Identity, delivering single sign-on and role-based access control consistently across both clouds for patients, providers, and staff.
Enforce HIPAA-grade security and monitoring
End-to-end encryption in transit and at rest, RBAC, and continuous monitoring and auditing were applied across the estate to keep the platform compliant and every access event traceable.
The technical solution
A block-level view of the system we designed and delivered — data and control flowing across each stage.
What the users see
A wireframe of the experience we shipped — laid out for the people who use it every day.
A cloud foundation built to scale and stay secure
From edge to data tier, we design layered, observable architectures with security and compliance engineered in — deployable to AWS, Azure, or GCP as single-cloud, multi-cloud, or hybrid.
Security and compliance, engineered in
From identity and encryption to detection and audit-ready evidence, we build to HIPAA, SOC 2, and PCI-DSS so you can clear procurement and prove it.
Outcomes delivered
- Consolidating hardware onto elastic cloud services reduced infrastructure cost by 35 to 45 percent and lifted operational efficiency by 40 percent.
- Load balancing and caching across AWS and GCP improved system performance by 30 to 40 percent and eliminated the peak-traffic bottlenecks that had caused downtime.
- The multi-cloud design tripled capacity headroom and sustained 99.9% uptime through automated failover and disaster recovery.
- End-to-end encryption, RBAC, and continuous auditing brought the platform into full HIPAA compliance across every region.
- With vendor lock-in removed and scale proven, the insurer is now positioned to expand its digital healthcare services with confidence.
