Set default bucket storage class

To change a bucket's default storage class you make a PUT request that is scoped to a bucket, and you use the storageClass query string parameter along with a <StorageClass> element in the request body.

Note that changing a bucket's default storage class does not affect the storage class of objects that already exist in the bucket. For more information, see the Per-Object Storage Classes page.
