Building high-concurrency clinical platforms requires zero-trust network boundaries, KMS envelope encryption, dedicated database read replicas, and rapid automated failovers.
Database clusters and clinical compute nodes reside exclusively on isolated private subnets with no direct public internet gateways. Ingress traffic is strictly mediated through Web Application Firewalls (WAF) and reverse application proxies.
Patient Identifiable Information (PII) is encrypted with distinct data encryption keys (DEKs) wrapped by master customer keys (CMKs) rotated automatically on an annual schedule.
Deployments run across Kubernetes (EKS/AKS) or AWS ECS with automated pod autoscaling based on CPU, memory, and concurrent clinical WebSocket connections.
