Multi-CDN Configuration and Dynamic Switching in AWS MediaTailor SSAI Environment – Part 1

An AWS blog explains a multi-CDN SSAI setup in MediaTailor that splits content and ad segments for delivery.

By combining ContentSegmentUrlPrefix, AdSegmentUrlPrefix, Configuration Aliases, and playerParams, each session can dynamically switch CDNs.

In server-side reporting mode, ad tracking is preserved, and reportingMode must be specified when initializing the POST session.

The approach helps OTT operators optimize for ISP conditions, improve resilience, and manage delivery costs more flexibly.
