Optimize performance for CDN and MediaTailor integrations
Maximize the performance of your AWS Elemental MediaTailor ad insertion implementation by optimizing your content delivery network (CDN) configuration. These settings ensure efficient content delivery and optimal viewer experience.
For detailed caching and routing optimization guidance specific to SSAI implementations, see CDN performance optimization. The consolidated optimization guide provides comprehensive caching settings, request routing configuration, and performance benchmarks that apply to all MediaTailor CDN integrations.
Common performance challenges
SSAI implementations with CDNs can face several performance challenges:
- Manifest manipulation overhead
-
MediaTailor performs real-time manifest manipulation, which can introduce latency if not optimized properly. The following can introduce latency:
-
Processing time for ad decision server (ADS) requests
-
Time required to modify manifests with ad segment references
-
Additional processing for personalization
-
- Cache efficiency issues
-
Personalized manifests can reduce CDN cache efficiency because:
-
Each viewer may receive a unique manifest
-
Session parameters can fragment the cache
-
Dynamic content requires careful cache configuration
-
- Origin load spikes
-
Improper caching can lead to origin load spikes during:
-
High-traffic events
-
Cache refreshes
-
CDN configuration changes
-
- Ad-related playback issues
-
Ad insertion can cause playback disruptions such as:
-
Buffering during ad transitions
-
Quality differences between content and ads
-
Playback failures when ads cannot be retrieved
-
