Vitayou – Case Study
Vitayou is a Turkey-based healthcare company building a digital healthcare platform designed to deliver healthcare experiences securely and at scale. As a company new to AWS, Vitayou engaged Onkatec to establish a secure and automated cloud foundation for its platform from the outset.
Customer Challenge
As a greenfield build, every decision set a precedent. Networking, identity, encryption, and delivery tooling all had to be production-grade from day one, with no existing AWS footprint to build on.
The healthcare domain added a second layer of requirements. Data privacy, availability, and auditability are commercially and regulatorily critical, so the platform needed encryption at rest and in transit, least-privilege access, and environment isolation from the start.
Finally, the platform spans multiple independently deployed services — backend, frontend, Directus, and the API — each of which needed a fast, automated, and repeatable release path across development and production.
Partner Solution
Onkatec delivered a complete cloud-native platform defined in Terraform and operated across a three-account AWS Organizations structure in eu-central-1. Amazon EKS runs the platform on Kubernetes 1.35, with separate production and development clusters using private endpoints and Graviton worker nodes — On-Demand in production and Spot in development for cost optimization.
Delivery is automated through Jenkins, with environment-specific pipelines and branch separation between development and production. A private HTTPS Application Load Balancer handles GitHub webhook triggers, so a push or merge to a target branch automatically starts the build and deployment for the right environment. Each job is mapped to its branch, AWS account, ECR registry, and EKS cluster.
The data layer uses Amazon RDS for both PostgreSQL and MariaDB — PostgreSQL for Directus and other services, MariaDB for the backend — with encryption and automated daily snapshots. Amazon ElastiCache for Valkey provides managed caching with encryption at rest and in transit. AWS Secrets Manager centralizes application environment variables and sensitive data, automatically synchronizing them into the EKS environment so no long-lived static credentials are needed.
Security and governance run through IAM Identity Center for SSO, AWS KMS for managed encryption keys, and IRSA for pod-level permissions. Separate management, production, and development VPCs span three Availability Zones, connected by VPC peering, with AWS Client VPN providing secure administrative access. Cost is governed through AWS Budgets, Cost Explorer anomaly detection, and Spot capacity in development.
Results and Benefits
Vitayou now runs a production-grade platform on AWS: two EKS clusters, four encrypted RDS instances, multiple ElastiCache Valkey groups, and seven container repositories, all live in production. The Jenkins pipelines have removed manual deployment steps, with each service building and deploying to its correct environment automatically.
Performance tuning on the PHP-FPM backend and Directus service — including increased worker capacity and rebalanced CPU limits — significantly reduced the high, variable response times observed in the development environment and confirmed stable production performance.
Security is enterprise-grade from day one: IAM Identity Center SSO, KMS-managed keys, Secrets Manager, encryption at rest and in transit, and three-account isolation with Client VPN access. The entire environment is reproducible through Terraform, with budgets and anomaly detection keeping cost under control.
