Helix Stream

Multi-region streaming platform with adaptive bitrate and a sub-200ms control plane.

Helix Stream

Overview

A global low-latency video streaming service serving millions of concurrent viewers across five regions.

Challenge

The legacy CDN setup introduced 4-6 second latency and frequent stalls during live events with concurrent viewership spikes.

Solution

We re-architected the control plane on Kubernetes with regional edge nodes, custom ABR logic, and a React-based player optimized for mobile networks.

Outcomes

Sub-200ms glass-to-glass latency
60% reduction in rebuffer ratio
Scaled to 4M concurrent viewers without incident
