Cross Datacenter Replication And Failover For Disaster Recovery

via “multi-datacenter deployment with geo-replication”

Unique: Integrates multi-datacenter deployment into the application deployment model (deployment.xml) with automatic document replication and query routing policies managed by the Cluster Controller. Replication is asynchronous to minimize write latency while maintaining eventual consistency.

vs others: More integrated than external replication tools because multi-datacenter logic is built into Vespa's core deployment and cluster management, enabling automatic failover and consistent query routing without additional infrastructure.
