Resilience

KVS provides a multi-level architecture that uses cross-region replication, multi-AZ disaster recovery (DR), full redundancy, slow node detection, and other technologies to ensure data durability and reliability.

KVS provides up to 99.9999999999% (12 nines) data durability and 99.99% availability, which are much higher than those of the traditional architecture.
