Consider storing your data in a multi-regional or dual-regional bucket location if high availability is a top requirement.
This ensures that your data is stored in at least two geographically separated regions, providing continued availability even in the rare event of a region-wide outage, including ones caused by natural disasters.
All data, regardless of storage class, is stored geo-redundantly in these types of locations, which allows you to use storage lifecycle management without giving up high availability.
