Engineering a high-concurrency, HIPAA-gated video engine capable of sustaining 50,000+ simultaneous consultations with zero jitter and 99.99% global availability.
Trusted by Leading Fortune 500 Innovators
Global healthcare provider requiring a decentralized video infrastructure for multi-specialty consultations.
SRE Architect + WebRTC Specialist + DevSecOps Lead embedded within the Clinical Product division.
Transitioning from a centralized legacy server to a distributed mesh to handle 10x traffic surges.
Globally distributed SFUs (Selective Forwarding Units), K8s autoscaling, and end-to-end HIPAA encryption.
The client’s legacy telehealth platform relied on a monolithic P2P signaling server that crashed during peak hours (8 AM - 10 AM EST). With a 2M+ patient base, even a 1% failure rate resulted in thousands of missed clinical appointments and severe provider frustration.
The risk was clinical and compliance-related: session drops occurred during critical post-op reviews, and the lack of a standardized recording policy created HIPAA audit vulnerabilities. The enterprise required a transition to a 'Resilient Mesh' that could scale horizontally across time zones.
Crashed at 5,000 concurrent users due to signaling server bottlenecks.
Sustains 50,000+ simultaneous sessions with regional load-balancing.
No consistent log of who accessed signaling data or when.
Immutable logs and end-to-end encryption with rotating room keys.
Switching from Wi-Fi to 5G often resulted in a dropped consultation.
ICE-restart logic and packet-loss concealment ensure session persistence.
Real-time network quality sensing downgrades video resolution without dropping the audio-diagnostic stream.
Performance metrics are extracted without ever exposing Patient Health Information (PHI) to the analytics layer.
New features are deployed to 1% of traffic initially, ensuring a platform crash never affects the entire patient base.
Pre-built OAuth2 integration for rapid medical staff and patient authentication.
Production-ready dashboards for monitoring packet loss, jitter, and MOS scores.
Predictive scaling logic based on historical peak appointment times.
Right-sizing regional SFU clusters to reduce monthly AWS bandwidth costs by 22%.
Horizontal scaling enabled the platform to handle global surges during morning peak hours without performance degradation.
Regional edge-routing reduced packet delay, ensuring a broadcast-quality experience for specialists.
Resilient ICE-restart logic eliminated drops during mobile network handovers (4G to Wi-Fi).
Client Testimonial
Coretus didn't just fix our video calls—they engineered a global life-saving infrastructure. We moved from constant crashes to a high-concurrency mesh that handles 50,000 concurrent sessions with the exact level of HIPAA traceability required for board-level risk sign-off.
