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.
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.
