THE CHALLENGE

A major entertainment client needed a live streaming platform for a one-time concert event in Japan. The timeline was aggressive: 14 days from initial brief to production delivery. No existing infrastructure. No room for failure.

Requirements:
  • Single 25-minute live broadcast
  • 250,000 concurrent viewers expected
  • Mobile and desktop support
  • Zero tolerance for downtime during the event
THE SOLUTION

We deployed a fully redundant, cloud-native streaming architecture across two AWS regions: Tokyo (ap-northeast-1) and Seoul (ap-northeast-2). Failover was automatic. The entire stack was Infrastructure as Code from day one.

Core Stack
CloudFront Global CDN with custom origin failover configuration
S3 Origin storage for HLS segments with cross-region replication
Lambda Real-time video processing and manifest generation
DynamoDB Viewer session management and analytics ingestion
End-to-end delivery
  • Video ingest and transcoding pipeline
  • Adaptive bitrate streaming (HLS)
  • Global content delivery with edge caching
  • Real-time viewer analytics dashboard
AWS COORDINATION

CloudFront default limits would not support the expected traffic spike. We engaged directly with AWS to:

  1. 1. Request and receive limit increases for concurrent connections
  2. 2. Negotiate event-based pricing for the traffic burst
  3. 3. Pre-warm edge locations in the APAC region

This coordination reduced projected CDN costs by 40% while ensuring capacity headroom.

RESULTS

The stream ran without incident. No buffering complaints. No regional outages. The client's audience watched a flawless 25-minute broadcast.
