Storage classes
A storage class is a named storage tier available within a region. Each one represents a different way of storing object data, so you can match data to the durability, performance, and cost profile it needs. Common examples are a standard tier, a reduced-redundancy tier, and an archival tier.
Storage classes are defined by platform administrators, not by workspace users. They are region-scoped, so the set of tiers you can choose from can differ from one region to the next.
What a storage class describes
Section titled “What a storage class describes”Each storage class has a name, such as STANDARD, REDUCED_REDUNDANCY, or
ARCHIVE, an optional description, and the characteristics of its tier, for
example how durably and economically object data is stored. Those
characteristics are what set one tier apart from another. The underlying storage
configuration is managed on the cluster by administrators; the service exposes
the tier itself so you can choose between them, not the low-level storage layout.
Region scope and the default class
Section titled “Region scope and the default class”Because a storage class belongs to a region, the available tiers depend on the region. A region can mark a storage class as its default. A bucket may reference its own default storage class, and when it does not, the region’s default stands in.
