Choosing a Cloud Storage Bucket Location Type

Matching location type to application needs means choosing the smallest failure scope that still meets uptime goals and the closest placement that still meets speed goals. An application that must keep running through a regional outage needs cross-region redundancy, while an application that only needs to survive a zonal outage can use regional protection.

• Choose zonal when the workload needs the highest storage performance in one zone and can tolerate reduced availability during a zonal outage.
• Choose regional when the workload runs in one region, needs protection against a zonal failure with automatic failover, and benefits from low latency to nearby compute.
• Choose dual-regional when the workload runs in two regions, needs protection against a regional failure, and needs fast replication between the pair with Turbo replication.
• Choose multi-regional when the workload needs protection against a regional failure and wide geographic availability beyond a single pair of regions.
