Resilience

OBS offers a five-level reliability architecture. It ensures data durability and availability by leveraging cross-region replication, disaster recovery across AZs, device and data redundancy in an AZ, and detection of slow disks and bad sectors.

OBS delivers up to 99.9999999999% (12 nines) of data durability, and up to 99.995% of data availability, far higher than a conventional architecture would offer.
