Telehealth Pod Autoscaling — 100K Daily Consultations

The Challenge

Telehealth startup grew 20x post-pandemic. Video consultations dropping at 10K concurrent, PHI data handling not HIPAA-compliant at scale.

✗Video drops above 10K concurrent sessions
✗PHI data flowing through non-BAA services
✗No audit trails for patient data access
✗Single-region deployment causing latency for rural patients

Our Solution

Rebuilt on GKE with Google HIPAA BAA, end-to-end encrypted WebRTC via TURN servers, auto-scaling media servers, and comprehensive audit logging.

Deployed GKE cluster under Google Cloud HIPAA BAA
Implemented TURN/STUN servers for NAT traversal with E2E encryption
Auto-scaling media server pods based on active session count
Built HIPAA-compliant audit logging for all PHI access
Multi-region deployment for sub-100ms video latency nationwide
Results & Impact

Platform serves 100K daily consultations across 40 states with zero compliance incidents.
