How do you design clustering systems with cross-region data synchronization?

Cross-region clustering uses data replication, eventual consistency models, and region-aware aggregation strategies.

Global systems collect data from multiple regions, which introduces latency and consistency challenges. Clustering systems either centralize data in a global region or compute local clusters per region and merge them later. Synchronization is handled using replicated storage systems and asynchronous updates. Conflict resolution strategies ensure consistency across regions.
