In an exploration of challenges faced by betting app developers, the text outlines solutions for three major real-time data issues: limitless live update recipients, data synchronization, and upstream gameplay events. To tackle the first issue, it recommends using a pub/sub architecture, which decouples event producers and consumers, allowing apps to scale efficiently without redesigning system architecture. For data synchronization, the text suggests using Serial JSON Patches and CRDTs to maintain data integrity while minimizing bandwidth usage, ensuring updates are reliable and ordered. Finally, it addresses upstream gameplay events by employing message queues and serverless architecture to manage spikes in activity, ensuring messages are processed in order and preventing failures. Ably's infrastructure, based on its Four Pillars of Dependability, offers robust solutions for these challenges, providing scalability, reliability, and integrity in real-time data handling.
