Design patterns for sports apps and live event platforms

In this article, the author discusses three common challenges faced by game and live event developers while building real-time applications. These include handling a theoretically limitless number of bettors receiving live updates (Problem 1), ensuring data synchronization across devices (Problem 2), and managing upstream game play events (Problem 3). The author provides solutions to these problems using patterns such as Pub/Sub, serial JSON patches, CRDTs, and message queues. These patterns help in scaling downstream data to devices, maintaining data integrity, and ensuring fault tolerance in the system.
