High-Level Design

When a player updates the score, the following tasks are executed:

1. The client establishes a WebSocket connection to the load balancer for instantaneous communication

2. The load balancer redirects the client's request to the nearest data center

3. The server modifies the score in the sorted set data structure within Redis

4. The serverless function updates the entries in the relational database by utilizing the write-behind cache pattern
