How Do a Bucket's Storage Class and Storage Resource Package Types Relate?

A bucket's storage class is not directly related to resource package types. Resource package types are related to the storage class of objects in the bucket.

Table 1 lists the storage resource packages provided by OBS.

Table 1 Description of resource packages

Resource Package

Function

Constraints

Standard storage (single-AZ)

Covers Standard storage for data stored in a single-AZ bucket.

The packages can only be used in the region specified during the purchase.

Assume that you purchased a Standard storage (single-AZ) package in the CN North-Beijing4 region. This package can only cover the Standard storage for data stored in a single-AZ bucket in the CN North-Beijing4 region.

Standard storage (multi-AZ)

Covers Standard storage for data stored in a multi-AZ bucket.

The packages can only be used in the region specified during the purchase.

Outbound Internet traffic

Covers network traffic generated for transferring data of the Standard storage class from OBS to local devices over the Internet.

The packages can only be used in the region specified during the purchase. This type of package can be used for both single-AZ and multi-AZ buckets.

The traffic generated for downloading the restored Infrequent Access or Archive or Deep Archive objects cannot be covered by outbound Internet traffic packages. Such traffic can only be billed on a pay-per-use basis.

Pull traffic

Covers network traffic generated for pulling data by CDN from OBS (served as the origin server).

The packages can only be used for OBS 3.0 buckets in the region specified during the package purchase. This type of package can be used for both single-AZ and multi-AZ buckets.

Pull traffic packages can only be used when you:

  • Bind an acceleration domain name through OBS Console.
  • Add an acceleration domain name through the CDN console, where the origin server is set to an OBS bucket domain name.

Pull traffic packages do not cover the traffic generated when a third-party CDN pulls data from Huawei Cloud OBS.

Pay special attention to the following points:

  • Ensure that the storage resource package you purchased matches the storage class of the objects in the bucket. Otherwise, the resource package may fail to cover your usage, and you will be billed on a pay-per-use basis.
  • Currently, no Infrequent Access resource packages are available, so Infrequent Access objects in a bucket are billed on a pay-per-use basis.
