5. What Drives Live Event Scale?
• Peak Concurrent Viewers
• Join Rate
• Geographic/Regional Concentration
Audience Characteristics
Video Characteristics
• Encoded Bit Rate
• Number of formats & profiles
• Segment Duration
6. How does internet Video work?
1 - Camera/Source generates Video
1 2
2 - Encoder & Packager create
Segmented Video and Manifests for
HLS/DASH

3 - Player is initiated via a client
requesting a link to the video
(master manifest)
5 - Player requests video segments in sequence
4 - Player requests playlist(s)/manifest(s)

6 - Steps 4 & 5 repeat until video ends.

8. Being Redundantly Redundant
• Diverse signal acquisition paths (satellite, terrestrial, multiple networks/links)
• Redundant Encoders with time/epoch locking (primary/secondary stream)
• Encoders writing to redundant origins (packagers/storage) in multiple regions
• DNS-based or API-based traffic management and stream selection by region
• Health checks and failover between primary/secondary in region or across regions

12. Video Delivery Optimization
• Ingest optimization via S3TA, Media-Connect, Direct Connect or other methods
• Redundancy and regional localization as appropriate
• Encoding/Packaging configuration
First-mile
13. Video Delivery Optimization in CloudFront
Middle-mile
• Connection keep-alive in cache fill path all the way to origin
• Chunked-transfer encoding
• Hierarchical/Regional caching and Connection Collapsing
• AWS Backbone provides low-latency, high throughput, low-congestion network
• Range Request consolidation & background fetching
• Negative Caching to protect origin
14. Video Delivery Optimization in CloudFront
Last-mile
• Connection keep-alives
• Protocol Optimization (BBR, MTU, HTTP-2, QUIC/HTTP-3)
• Lots of capacity (>120Tbps of network connectivity)
• Direct Peering with many networks
• Embedded POPs deeper within major consumer ISP networks
• Perimeter Protection @ Edge with WAF & Shield
31. Take Away
• Multiple CDN is always a good strategy
• Choose right services to serve business
• Reliable storage to persist logs for monitoring
• Enhancement by whole picture understanding
