[Cloud Storage (Benifits)]
What does Continental-scale and SLA-backed replication refer to?

A

A single bucket offers nine regions across three continents, providing a Recovery Time Objective (RTO) of zero. In case of an outage, data can be accessed in an alternate region without a failover and failback process. Turbo replication offers a 15 minute Recovery Point Objective (RPO) SLA.
