Application Example 1: Authorizing Access Permissions Required for Adding an External Bucket Through the Bucket ACL

A bucket ACL can be used to grant the read and write access to a bucket. If only the read access to the bucket is granted, the authorized user can only add the bucket and list objects in the bucket, but cannot upload objects to the bucket. If the read and write access to the bucket is granted, the authorized user can upload objects to the bucket. Permissions controlled by a bucket ACL are as follows:
