Overview
A prestigious hospital and university in the Bay Area relied heavily on extensive on-premise infrastructure to support several hundred researchers and healthcare professionals. As demand for scalability, reliability, and data security increased, the organization recognized the need to modernize its legacy systems.
The objective was clear: migrate all applications to the cloud while strengthening security, enabling high availability, automating operations, and ensuring strict adherence to HIPAA regulations all while reducing both capital and operational expenditures.
Rysun partnered with the client to execute a secure, compliant, and scalable migration to Google Cloud Platform (GCP), transforming the health registry platform into a modern, cloud-native environment.

Industry
Healthcare & Academic Research Institution

Challenge
Modernize legacy on-premise infrastructure while ensuring HIPAA compliance, security, scalability, and zero service disruption.

Solution
Secure, HIPAA-aligned migration to Google Cloud using GKE, Cloud SQL, advanced networking, and GitOps-driven automation.
Challenge
The migration presented a range of complex challenges across business, process, and technology dimensions. From managing rising infrastructure costs and stringent data protection requirements to ensuring zero-disruption transitions and modernizing legacy systems, each area demanded careful planning and execution. Addressing these challenges was critical to building a secure, scalable, and future-ready healthcare environment.
Business Challenges
- High infrastructure costs driven by legacy systems
- Requirement for strong HIPAA-aligned data protection controls
- Need to reduce CapEx and OpEx without compromising performance
Process Challenges
- Migrating mission-critical healthcare applications without downtime
- Establishing secure workflows across regions
- Ensuring seamless access for hundreds of researchers and clinicians
Technology Challenges
- Outdated infrastructure lacking automation and elasticity
- Limited scalability to support growing research and healthcare demands
- Re-architecting systems to meet cloud-native and compliance standards
Rysun’s Solution
Rysun designed and implemented a fully managed, secure, and scalable architecture on Google Cloud Platform. The solution combines robust data protection, containerized workloads, and advanced networking controls with automated, GitOps-driven operations. Rigorous testing ensured the platform met performance, reliability, and compliance requirements before deployment.
Secure Data Infrastructure with Cloud SQL
- Private IP-only configuration with no public exposure
- Encrypted connections to safeguard protected health information (PHI)
- Managed database services reducing operational overhead
Containerized Workloads on Google Kubernetes Engine (GKE)
- Private GKE clusters with restricted control plane access
- Firewall-controlled workload access
- Auto-scaling capabilities to handle fluctuating usage
Advanced Networking & Security Controls
- Custom VPC design ensuring strict internal isolation
- Granular firewall rules for traffic control
- HTTPS Load Balancer with enforced SSL policies
- Cloud Armor for DDoS protection
- Cloud NAT for secure outbound connectivity
GitOps-Driven Automation
- Flux CD implemented for GitOps-based deployments
- Continuous alignment between cluster state and Git configuration
- Automated, consistent, and auditable infrastructure management
Testing & Validation
The final solution underwent rigorous:
- Functional testing
- Performance benchmarking
- Auto-scaling validation
- High availability (HA) testing
This ensured the platform met both operational and regulatory requirements before go-live.
