Mediatailor

A leading server-side ad insertion (SSAI) and channel assembly service within the AWS ecosystem, widely adopted by OTT and FAST channel operators

MediaTailor offers flexibility by allowing users to select their own preferred vendors for components such as the content delivery network, ad decision server, and origin server, integrating seamlessly with most standard CDNs, ad decision servers, and origin servers accessible over HTTP.¹ AWS Elemental MediaTailor is an Amazon Web Services channel assembly and personalized ad-insertion service that enables video providers to build linear over-the-top (OTT) channels from existing content and monetize those channels or other live streams through personalized advertising.² Rather than inserting ads during playback on individual client devices, MediaTailor performs ad insertion upstream, before video delivery, eliminating the need for complex, device-specific configurations.¹ The service is compatible with standard manifest and playlist formats such as HLS and DASH, enabling broad device and player support and making it particularly suited to the FAST (Free Ad-Supported Streaming TV) model.¹ For advertisers and content providers who require accurate measurement, MediaTailor achieves IAB-level playback metrics through playback observation APIs on the viewer device, and also provides server-side ad metrics for devices where client-side changes are not feasible.¹ Source 1: trackit.io — Content Monetization through Server Side Ad Insertion (SSAI) Source 2: newrelic.com — AWS Elemental MediaTailor
