A realtime betting solution has to deal with an unpredictable and rapidly changing number of end-users. Large connection spikes are common - especially during events such as the Super Bowl, the World Cup, or a Formula 1 Grand Prix, which attract millions of simultaneous bettors. These users need to receive updates (new odds, latest scores) and must be able to place bets in realtime (often, when it comes to live sports, even a second can make a huge difference).

Ably offers a simple, dependable, scalable, and secure way to distribute messages from Kafka to web, mobile, and IoT clients anywhere in the world.
