How We Handled Real-Time Traffic Spikes During the World Cup With a Lightweight Mini App
During the last football World Cup, a lightweight live-score mini app was developed to manage real-time traffic spikes. The app faced significant challenges, particularly during goal events, which caused massive surges in traffic. Optimizations in architecture and data handling were implemented to maintain performance and reduce latency.
- ▪The app aimed for ultra-fast score updates and minimal server costs.
- ▪Traffic spikes occurred primarily after goals, leading to a need for efficient data handling.
- ▪Redis became the backbone of the system, managing real-time data during peak events.
