  **Transparent Cloud Tiering**
  Transparent cloud tiering is a licensed function that enables volume data to be copied and 
  transferred to cloud storage. The system supports creating connections to cloud service 
  providers to store copies of volume data in private or public cloud storage. 
  
  With transparent cloud tiering, administrators can move older data to cloud storage to free up 
  capacity on the system. Point-in-time snapshots of data can be created on the system and 
  then copied and stored on the cloud storage. An external cloud service provider manages the 
  cloud storage, which reduces storage costs for the system. Before data can be copied to 
  cloud storage, a connection to the cloud service provider must be created from the system. 
  
  A cloud account is an object on the system that represents a connection to a cloud service 
  provider by using a particular set of credentials. These credentials differ depending on the 
  type of cloud service provider that is being specified. Most cloud service providers require the 
  host name of the cloud service provider and an associated password, and some cloud 
  service providers also require certificates to authenticate users of the cloud storage. 
  
  Public clouds use certificates that are signed by well-known certificate authorities. Private 
  cloud service providers can use self-signed certificate or a certificate that is signed by a 
  trusted certificate authority. These credentials are defined on the cloud service provider and 
  passed to the system through the administrators of the cloud service provider. A cloud 
  account defines whether the system can successfully communicate and authenticate with the 
  cloud service provider by using the account credentials.
