Before you can use Hologres, you must use your Alibaba Cloud account to purchase a Hologres instance. This topic describes how to purchase the three types of Hologres instances and the billing methods of the three types of Hologres instances. You can purchase a Hologres instance based on your business requirements and budget.
Prerequisites
An Alibaba Cloud account is created.
Real-name verification is complete.
Access control
By default, the Alibaba Cloud account that is used to purchase an instance is a superuser of the instance. A superuser of an instance has all permissions on the instance.
A RAM user must be authorized by the Alibaba Cloud account before the RAM user can be used to purchase instances. For more information, see Grant permissions on Hologres to RAM users. A RAM user can follow the same procedure as an Alibaba Cloud account to purchase an instance.
