A New Live Streaming Origin Built for Global Scale

In preparation for the FIFA World Cup 2026, a major UK-based broadcaster transitioned its live streaming origin from the deprecated AWS Elemental MediaStore to Momento, aiming to serve tens of millions of fans seamlessly. This complex migration involved not just replacing a core media storage and origin layer but also ensuring that Momento met stringent requirements for latency, reliability, and operational visibility while supporting existing infrastructure like encoders, packagers, and CDNs. To achieve this, the broadcaster and Momento conducted extensive tests, including latency benchmarks and load drills, to ensure performance parity or improvement and operational observability that aligns with current monitoring systems. The design goal was to make the transition as seamless as possible, maintaining existing HTTP semantics, transient data policies, and access control while introducing configurable object TTLs and ensuring long-term durability. With the new system in place, the broadcaster is poised to deliver a flawless viewing experience for the World Cup, reflecting a strategic move to an actively developed platform that aligns with future technological advancements.
