Before you use Hologres, you must purchase a Hologres instance. This topic describes how to purchase a Hologres instance by using an Alibaba Cloud account.


  • An Alibaba Cloud account is created.
  • Real-name verification is completed.

Background information

By default, the system sets the Alibaba Cloud account used to purchase an instance as a superuser of the instance. The superuser has all permissions on the instance.

You can purchase a Hologres instance as a RAM user only after the required permissions are granted to the RAM user by using your Alibaba Cloud account. For more information, see Grant Hologres-related RAM permissions to a RAM user. The procedure of purchasing a Hologres instance for a RAM user is the same as that for an Alibaba Cloud account.
