Using Object Storage from the Control Portal

Updated by Richard Seroter on Jan 7, 2015


CenturyLink Cloud now has a robust, geo-distributed Object Storage service capable of storing any type of digital content. Perfect for data backups, media distribution, and file transfers. The CenturyLink Cloud Object Storage is Amazon S3-compatible and accessible from the CenturyLink Cloud Control Portal or via API. This KB article explains how to interact with Object Storage from the CenturyLink Cloud Control Portal.

    • Enter an email address for the user. Note that this value must be unique across the platform and can't be reused. The account cannot be deleted and the email address cannot be changed. We recommend using a distribution email address, rather than the email address of a single person. If needed, we will use this email address to reach out to the technical contacts who manage the bucket. Create User

    • The drop-down list shows all Users in this account, and two built-in Groups: All Users and Authenticated Users.
    • When you add All Users to a bucket -- and give it read permissions -- you are giving public Internet access to the bucket.
    • If you add the Authenticated Users group to the bucket, then any Object Storage user can access the bucket.
  4. For any existing user, you can modify their permissions by adding or removing check marks associated with each permission. Note that the bucket owner always has full control.

    • To delete the user from the grantee list, click the red x to the right of the record.
    • Changes made to a bucket are instantly committed. For instance, if you add All Users with read permissions, then the buckets (and contained objects) are immediately available to anyone.
    • Likewise, if you use a 3rd party tool to manage Object Storage, changes to the grantee list are instantly visible in the Control Portal.
