Set up SSAI with a CDN for personalized video advertising
This section provides comprehensive guidance for integrating AWS Elemental MediaTailor server-side ad insertion (SSAI) with a content delivery network (CDN). Follow these steps to set up, configure, and optimize your SSAI CDN integration.
Server-side ad insertion (SSAI) is a technology that seamlessly inserts personalized advertisements into video streams at the server level rather than the client level. When combined with a CDN, you create a robust, scalable solution for delivering personalized advertising to global audiences with minimal latency.
In this topic, we use the term manifests to refer collectively to multivariant playlists, media playlists, and MPDs.

Benefits of CDN integration
Integrating SSAI with a CDN delivers these key benefits:
- Improved viewer experience
-
Properly configured CDNs reduce buffering, startup times, and playback errors during ad transitions. This results in higher viewer engagement and satisfaction.
- Cost reduction
-
Efficient caching strategies minimize origin requests. This reduces data transfer costs and origin server load, particularly important for high-volume ad-supported content.
- Scalability
-
Optimized CDN configurations handle traffic spikes during popular events without degrading performance, ensuring your personalized ads are delivered even during peak viewing times.
- Global reach
-
Properly configured CDNs deliver content with low latency to viewers worldwide, regardless of their location, expanding your potential audience.
- Seamless ad transitions
-
Optimized CDN configuration ensures smooth transitions between content and ads, creating a broadcast-quality viewing experience.
