The Australian Open is one of the world's premier annual sporting events, attracting a record-breaking 1.11 million fans to Melbourne Park in 2024 and reaching over 558 million unique global viewers, a 57% increase from the previous year. The event faces significant challenges in delivering a seamless digital experience to its global audience, particularly with regards to realtime data delivery and monetizing the digital audience at scale. Achieving this requires meticulous planning, ensuring redundancy across multiple regions, and having fallback protocols in place to support websocket streaming on older devices. Tennis Australia has partnered with Ably, a global realtime experiences platform, to meet these challenges, enabling them to focus on delivering engaging content and enhancing the fan experience. The partnership has allowed Tennis Australia to avoid building complex realtime infrastructure, instead trusting Ably to manage scalability and growth, while also driving innovation in areas such as generative AI-powered tennis leagues.
