About The Customer
The customer is a rapidly growing healthcare technology provider focused on delivering secure, patient-centric digital solutions. Their platform handles sensitive medical data, supports real-time clinical workflows, and must comply with strict regulatory requirements such as HIPAA. As they prepared to scale their operations, they needed a robust, secure, and compliant cloud foundation on Google Cloud Platform (GCP) to support future growth and innovation.
Ananta Cloud delivered a fully automated, secure, and compliant GCP Landing Zone tailored for healthcare workloads. The solution established a scalable multi-environment foundation with strong identity controls, network segmentation, and policy-driven governance. Using Terraform and CI/CD automation, Ananta Cloud ensured consistent deployments, rapid onboarding, and continuous compliance across the customer’s cloud ecosystem.
Key Challenge
-
The customer needed a HIPAA-aligned cloud foundation capable of securely handling sensitive patient data while meeting strict compliance requirements.
-
Existing infrastructure lacked standardization, governance, and visibility, making it difficult to scale securely across environments.
-
There was no centralized identity and access model, leading to inconsistent permissions and increased security risk.
-
Network design was scattered, without proper segmentation, VPC structure, or data exfiltration protection for healthcare workloads.
-
The customer required automation-first provisioning, but had no Infrastructure-as-Code or CI/CD processes to ensure repeatable, consistent deployments.
-
Limited tooling around monitoring and security scanning created gaps in observability, threat detection, and misconfiguration management.
Our Solution
To address the client's challenges, Ananta Cloud recommended migrating from the on-premises Oracle database to AWS Postgres RDS, leveraging a combination of AWS managed services for cost optimization, performance enhancement, and operational efficiency. The following services were utilized during the migration and post-migration process:
By combining IAM guardrails, VPC Service Controls, encryption policies, and audit logging, AnantaCloud delivered a Landing Zone that supports HIPAA-aligned security and future regulatory requirements.
AnantaCloud enabled:
Cloud Logging for all resources
Cloud Monitoring dashboards and alerts
Security Command Center for threat detection
This improved visibility, incident response, and ongoing compliance.
All Terraform code was deployed through CI/CD pipelines featuring:
automated plan/apply
policy checks
approval workflows
drift detection
This provided quick, reliable, and auditable cloud changes.
A multi-VPC design was created with:
private subnets
centralized ingress/egress controls
restricted inter-environment communication
VPC Service Controls for data exfiltration protection
This provided a highly secure network perimeter for healthcare workloads.
AnantaCloud defined a clear IAM strategy including:
role-based access control (RBAC)
least-privilege roles for teams
Cloud Identity integration for SSO
This reduced excessive permissions and created a clean, secure access model.
Organization Policies were applied at the org and folder levels to enforce guardrails such as:
restricting external IP assignments
enforcing CMEK for data storage
blocking project-level policy overrides
This ensured the environment remained consistent, compliant, and centrally governed.
AnantaCloud built standardized Terraform modules covering projects, networks, IAM, logging, monitoring, and security services. This ensured repeatable, version-controlled deployments across dev, test, and prod environments while eliminating manual errors.
