Live Events & Streaming Scale
Surviving traffic spikes for global broadcasts with resilient edge and observability
The Challenge
Spiky traffic during live events overwhelming origin APIs
Inconsistent cache behavior across regions
Limited real-time visibility into viewer experience and CDN health
Post-mortems that could not pinpoint whether issues were edge, origin, or player
Our Solution
Tuned multi-layer caching with cache-key discipline and stale-while-revalidate patterns
Implemented autoscaling policies based on custom metrics, not CPU alone
Built dashboards correlating CDN, API latency, and error budgets
Ran load tests that mimicked regional fan-out and encore traffic
Documented runbooks for brownouts, failovers, and graceful degradation
Measurable Impact
Proven
Rehearsal events validated headroom before flagship broadcasts
Better
Mean time to identify root cause dropped with unified telemetry
Steadier
Rebuffering and start-time metrics stayed within targets during spikes
More predictable
Rightsized origins and smarter TTLs reduced over-provisioning
